Changes in version 1.3.14 Beta: Bug fixes for: * Interface: * Excessive delay occurred when typing into labels in long projects. * Last digit of TimeText controls could not be manipulated in some formats. * (Windows, OS X) Play and Record shortcuts did not work after clicking in Device Toolbar. * (OS X, Linux) Crash occurred if Toolbars were reset during playback or recording. * Imports and Exports: * MP2 files were not importable without FFmpeg library or an import rule. * Files that could only be imported using FFmpeg imported as noise with no error message if FFmpeg was not available. * Files containing PCM audio but an incorrect extension (such as MP3) caused a freeze. * Effects and Analysis: * An empty command could be added to a Chain which then displayed a Nyquist error message when run. * Plot Spectrum didn't preserve signal level if multiple tracks were analyzed. * Other bug fixes: * Audacity has been provisionally fixed so that it can no longer create block files longer than the sample format or project format allows, and can no longer delete these, which led to data loss. Any overlong blocks found are preserved but "orphaned", so will appear as silence. * Orphan block files were wrongly reported if cutting or copying to the clipboard then reopening the project in the same session. * Fixed some crashes and incorrect movement of audio when dragging tracks. * (Windows) Data loss is now prevented when encountering a corrupted .aup file created in ANSI builds. * (Linux) Restore building if USE_PORTMIXER is not defined. Changes and Improvements: * Normalize: Faster processing and improved interface. Left-right balance in unsplit stereo tracks is now preserved by default, with a checkbox option provided to process stereo channels independently. * Spectrograms now allow window sizes up to 32768 and frequencies up to half the sample rate (the maximum possible). * Mix and Render now preserves clip length by not rendering white space between time zero and first audio, and preserves audio before time zero. To retain silence before the audio starts, generate silence after render. * Grouped some Edit Menu items into "Remove Audio" and "Clip Boundaries". * CleanSpeech Mode removed from Interface Preferences (it still runs if it was enabled in a previous Audacity but can only be turned off there). * (OS X) Added support for AudioUnit MusicEffects (but no MIDI support). * (Linux) Set the per-user files directory per the program name set in configure. * (Linux) Changed the default location of the Audacity temporary directory to be in /var/tmp not /tmp, so preserving the directory between reboots. ------------------------------------------------------------------------------- 3.

Compilation instructions First you must download wxWidgets. Audacity 1.3.14 requires wxWidgets 2.8.12 from: http://www.wxWidgets.org/ If you install the RPM, make sure you install the devel RPM as well, otherwise you won't be able to compile Audacity from source. To compile on Linux, Mac OS X and other Unix systems, execute these commands: ./configure make make install # as root To see compile-time options you can set, you can type "./configure --help". If you want to do any development, you might want to generate a configure cache and header dependencies: ./configure -C make dep To compile on Windows using MSVC++, please follow the instructions found in compile.txt in the "win" subdirectory. To compile using Xcode on Mac OS X, see the instructions in mac/compile.txt. For more information on compilation, please visit: http://audacityteam.org/wiki/index.php?title=Developer_Guide#Platform_Specific_Guides or e-mail us at: email@example.com -------------------------------------------------------------------------------- 6. Previous Changes going back to version 1.1.0 Changes in version 1.3.13 Beta: Bug fixes for: * Interface: * Cutting or copying from a track at a given sample rate into a track at another rate resulted in speed-changed audio. * Generating inside a clip could modify the clip length or create spurious clips. * Recorded stereo tracks were only half the height of imported or generated stereo tracks. Imported stereo files had a "1" appended to the track name. * Edit > Region Save did not save the cursor position. * (Windows) Projects crashed when clicking rapidly inside the interface or when applying repeated effects towards the end of audio tracks. * (Windows) Some Unicode characters could not be typed into labels, or caused a freeze using some input methods. * (OS X) Crash when quitting an empty project window, or when closing the main project window while a progress dialog was on screen. * Numerous other interface fixes including Dependencies dialog, Keyboard Preferences and spurious lines drawn on waveform. * Imports and Exports: * Support added for later versions of the optional FFmpeg library up to current FFmpeg HEAD. This should significantly improve FFmpeg support on Linux. FFmpeg downloads for Windows and Mac updated to v0.6. This fixes mono AAC files importing as stereo, though current 0.5 versions of FFmpeg will still work. * Both FFmpeg and LAME should now be properly detected even when other versions of those libraries exist on the system. * New warning (on by default) for importing uncompressed audio files. Better error messages when read-directly uncompressed files are missing. * Imported ID3v2 metadata tags were removed when exporting without the Metadata Editor appearing (for example, when using an export command in Chains). Note: As a result of this fix, ID3v1 tags must now be written by exporting using (external program) and an installed LAME. * U-Law/A-Law files with WAV headers now use the standard 18 byte fmt chunk, so should now be recognised by most telephony applications. * Variable bit rate MP3s exported using "MP3 Files" were larger than necessary because using the bit reservoir was disabled. * (OS X) Files imported from iTunes could create invalid characters in the .aup project file, causing an error when re-opening the project. Note: An error "reference to invalid character number" will still occur if re-opening a project created in previous Betas that contains such characters. To fix the issue, open a back-up copy of the .aup file in a text editor, turn off word wrap, then in the line indicated in the error message, remove the string of characters that starts with &# and ends with a semi-colon (;). * Other bug fixes: * Nyquist effects: fixes for crashes, incorrect slider behaviour and better support for backslashes, double quotes and Unicode characters. * (Windows and OS X) Processing of VST effects was substantially slower than in previous versions of Audacity. * (OS X 10.5 PPC) A first-time installation of Audacity Beta would hang on launch if VST effects were detected. * (Linux) Recordings made with the pulse device crashed or stalled when using overdub and/or software playthrough. * (Linux) Play-at-Speed crashed at 0.08 speed or lower if Audacity was configured with libsamplerate. Changes and Improvements: * Control Toolbar renamed to Transport Toolbar. * Device Toolbar (on by default) now contains all input and output device choices, including host and recording channels. Input/output choices are no longer in Mixer Toolbar on Windows XP or some older operating systems. New Transport > Rescan Audio Devices menu item to refresh the device list. * New "Sync-Lock Tracks" feature (turned on in the Tracks menu) to allow groups of audio and/or label tracks to retain synchronisation when the track length changes. * Equalization: New "Manage Curves" dialog for importing and exporting curves. * Noise Removal: New "Sensitivity" slider to adjust the noise threshold, and new option to isolate noise. * New "Extended Import" Preferences for specifying different importers to open specific file extensions. * Improved Automatic Crash Recovery with all project changes autosaved. * MIDI tracks can be vertically zoomed, time shifted and display bar lines. Note: the channel selection buttons are not available in 1.3.13. * (Windows and Linux) The window Close button and other system close or shutdown commands now quit on closing the last window. File > Close now always clears to a new, empty project. * (OS X) Simpler installer with top-level "Audacity" folder. Changes in version 1.3.12 Beta: Bug fixes for: * Imports and Exports: * AAC files could not be exported at 48000 Hz * When importing multiple native file formats using FFmpeg, all files after the first reverted to using the native importer * FFmpeg custom export window too large on 800 x 600 resolution monitors * Projects froze if files imported via On-Demand were no longer available * (Linux) WAV/AIFF exports were corrupted if overwriting an aliased file which had been imported using the command line * Labels: * Cutting or deleting a region in the waveform and label track did not move the labels in advance of the cut * Incorrect behavior snapping to labels and boundaries when Snep To was enabled * Labels can now be reversed if included with the audio selection * Other bug fixes: * When using non-English languages, Generate effects truncated the selected region * Mice with high-precision scroll-wheels could cause a crash * Changing recording preferences using the Transport menu did not update the menu in other open projects * (Windows 7) Clicking in a file open or save dialog caused files or folders to disappear from the list, and file filtering was broken Changes and improvements: * A hover tooltip is now provided if the Mixer Toolbar input selector cannot control the system slider for the selected input. * More intuitive behavior when moving and resizing labels by dragging * Support added for importing lists of files (LOF) containing relative paths * Export Multiple: new option to use a numerical prefix before existing label or track names; "Success" dialog now resizable * New Equalization preset "Inverse RIAA", with new button to invert other curves * Timer Record now remembers last scheduled duration * Meter Toolbar can now be made much narrower, and so more suitable for vertical orientation * New Preferences choice for "System" language which is used on first run instead of asking user to choose language * Warning now provided if WAV/AIFF exports are not successfully completed * (Linux) Improved icon set in compliance with freedesktop.org Icon Theme Specification 0.6 Changes in version 1.3.11 Beta: Bug fixes for: * Imports and Exports: * Bug when exporting partial selections caused too much audio to be exported is fixed. * Fix corrupt files exported through FFmpeg when metadata included, (metadata is now exported correctly in M4A files) * Prevent saving a new Audacity Project over an existing one as this could corrupt both projects. * Improved help for files that cannot be imported because the relevant optional library is missing. * Effects: * Allow effects which change the length of the audio they work on to also be applied to selected label tracks, thus keeping them synchronized. * Fixed inability in Nyquist plug-ins to add labels to an existing label track * (Mac) Equalization window was corrupted after Preview * (Linux 64-bit) Fixed crash Generating Click Track * Audio Devices: * Fixed bug causing recording to stop short when the recording sample rate is not supported by the sound device and libsamplerate is used for resampling. * Fix crash when opening Preferences on a machine where there are no available audio devices. * Fixes for bugs using Timer Record and Sound Activated Recording * User Interface: * Sizes of some dialogs adjusted to ensure they fit on the screen. * Fix for supposedly "hidden" items appearing on screen with large monitors. * Various keyboard shortcut and translation fixes. * Other bug fixes: * Several timing-dependent crashes and minor incorrect behaviors have been fixed * Windows installer now installs correctly over previous versions of Audacity Changes and improvements: * (Windows) Better icon file with higher resolution and transparency * New SoundFinder plug-in to label regions of audio between silences, so allowing silences between tracks to be excluded when exporting multiple Changes in version 1.3.10 Beta: Bug fixes for: * Imports and Exports: * Freeze importing audio files when Default View Mode set to Pitch (EAC) * Simultaneous On-Demand imports sorted incorrectly * WAV or AIFF files imported as noise if Preferences set to copy in the data at 24-bit quality * WMA exports corrupted if they contained metadata * Metadata Editor appeared before the Export window when exporting to any format * Effects: * Crash or hang using Equalization on longer tracks * Reverse did not reverse clip boundaries * Nyquist: * Excessive memory consumption led to slow processing or crashes * Values appearing in Nyquist effects text boxes were not always the default or previously entered values * Errors running Nyquist effects in European locales where comma used as decimal separator * VST effects remained in Effect menu even when re-scanned and no longer available * Truncate Silence produced incorrect results if silences spanned a block boundary * Other bug fixes: * Spurious "not writable/disk full" errors when saving projects * Playing, rendering or exporting multiple tracks led to desynchronised playback or loss of audio data * Crash opening Preferences when no recording and/or playback devices enabled or connected * Preferences window: OK button did not respond to ENTER when a tab selected in left-hand panel * Mixer Board solo button handling * (Windows) After a period launching correctly, Audacity sometimes did not come up on top at launch * (Mac OS X) Correctly installed Help folder could not be found * (Mac OS X and Linux) Output slider could affect VU playback meter which then did not reflect actual waveform volume level * (Linux) Undoing or redoing a label edit could cause a crash Changes and improvements: * Linked audio and label tracks disabled until a future Beta version so they can be bug fixed * Input volume slider will be disabled if it doesn't have proper control of system slider; use the system slider instead * Proper support for copying/pasting label-with-audio including label text; new Edit > Paste Text to New Label menu item to paste system clipboard * Contrast Tool now modeless, more intuitive handling of multiple project windows, various other minor improvements Changes in version 1.3.9 Beta: Bug fixes for: * Crash, slow launch or excessive CPU/memory use arising from automatic VST support: * VST instrument plug-ins should now be correctly ignored * VST effects now scanned only at start of first session that detects them, then cached; effects are now not loaded or opened until needed * New "Effects" tab in Preferences to enable/disable VST effects and enable VST rescan on next launch * Default View Mode now works * Chains now always apply their stored parameters rather than those last used in Effect menu * Non-MP3 files imported via drag or Recent Files caused crash if filter in file open window set to MP3 * AAC exports (using the optional FFmpeg library) were silenced * Generating audio always fitted the project in the window; fit now done only if generating in new track * View menu items/shortcuts incorrectly disabled when playing or recording * DTMF generator defaulted to zero duration on open * Unwanted interactions between linked audio and label tracks * Noise Removal shifted clips if the selection region included white space * (Windows XP) Failure to launch on some machines due to "incorrect configuration" issue * (Windows) Crash importing a stereo file while a screen reader such as JAWS is running * (Mac OS X): * Audio Units effects applied to all tracks in project even if not selected * QuickTime importer now handles files greater than 16-bit or 64000 Hz * Various other interface bugs Improvements: * Compressor: new option to compress based on peaks, improved attack and decay time support * Mixer Board: improved design, more responsive meters and now interacts fully with Track Panel in main window Changes in version 1.3.8 Beta: New Features: * Effects and Analysis: * VST Effects now display GUI by default * Faster Equalization and Noise Removal;

Collapse/Expand Tracks In Audacity 1.3, every track has an upward-pointing triangle at the bottom of the label area on the left side of the track. 2. Multiple clips per track In Audacity 1.2, there is one audio 'clip' per track. There is no easy way to time-shift part of a track without moving the rest. In Audacity 1.3, you can split a single track into multiple clips. You can move these clips around between different tracks, making it easy to construct complex compositions out of hundreds of smaller audio samples. 3. Selection Bar In Audacity 1.2, the current selection is contained in a status bar at the bottom of the window. In Audacity 1.3, this is replaced by a fully functional Selection Bar, which displays and controls the current selection (your choice of Start and End, or Start and Length), and the current audio position. The selection bar is fully editable - just click in any field and type to change the current selection precisely. In addition, many formatting options allow you to view times in different units, such as samples, CD frames, or NTSC video frames. 4. Improved Label Tracks Label Tracks are Audacity's way for you to create markings 3 and annotations within your project. In Audacity 1.3, Label Tracks are much improved, with support for overlapping labels, and support for modifying both the left and right edge of the label region just by clicking and dragging. 5. QuickTime and Audio Units on Mac OS X On Mac OS X, Audacity can now import and audio file supported by Apple's QuickTime technology. This includes .MOV and .MP4 (AAC) files. Unfortunately encrypted audio files (such as those from the iTunes Music Store) cannot be imported directly into Audacity - Apple does not allow this to be done easily because it would be too easy to circumvent the encryption this way. Also on Mac OS X, Audacity now supports Audio Unit plug-ins. Audacity searches for Audio Units in the usual location, in the system or user's Library folder. 6. Other features Better performance with large projects Project integrity check on open Transcription toolbar Upload Batch Cut lines CleanSpeech Changes in 1.2.4: * The File menu now includes a list of recent files. * The "Generate Silence" effect now prompts for a length. * Audacity is now built with Vorbis 1.1, which features better encoding quality and file compression. * Dragging sound files into the Audacity window now works on Mac OS X and Linux, as well as Windows. (Before, it worked only on Windows.) * The "View History" window can now discard old undo levels to save disk space on Windows. (This previously worked only on Linux and Mac.) * "Preferences" command is now in Edit menu. * "Plot Spectrum" command is now in Analyze menu. * Opening a project file saved by a later version of Audacity displays an intelligent error message. Also, trying to import a project file (instead of open it) displays an intelligent error message. * Audacity now compiles in Visual C++ .NET 2003. * Other minor bug fixes. * New or updated translations: Arabic (ar), Czech (cs), Finnish (fi), Hungarian (hu), Japanese (ja), Norwegian (nb), Slovenian (sl), Simplified Chinese (zh_CN), Traditional Chinese (zh_TW). Changes in 1.2.3: * Fixed a bug that caused recording to stop or display incorrectly after about 50 minutes on some Windows systems. (This was partly fixed in Audacity 1.2.2, but still didn't work on some systems.) * The Change Pitch and Change Tempo effects have been upgraded to use a new version of the SoundTouch library by Olli Parviainen, with better speed and higher quality. * libsndfile has been upgraded to version 1.0.11. * Fixed a bug that caused the program to run slowly when using the Envelope tool. * Shift-clicking on a mute or solo button now un-mutes (or un-solos) all other tracks. * Nyquist plug-ins can now accept strings as input. Also, a "Debug" button has been added to Nyquist effect dialogs, which allows you to see all of the output produced by Nyquist, for aid in debugging. * When the audio file referenced ("aliased") by an Audacity project is missing, Audacity will now always play silence. Before, Audacity would sometimes repeat the most recent audio that was played previously. * VU Meters will now always reset when audio I/O has stopped. * Fixed a major Mac-only bug that was causing Audacity to crash at seemingly random times, but especially during audio playback and recording. * New or updated translations: Italian (it), Hungarian (hu), Ukrainian (uk), Spanish (es). Polish (pl), Simplified Chinese (zh), Norsk-Bokmal (nb), French (fr). Changes in 1.2.2: * VU Meters added for both playback and recording. Click on the recording meter to monitor the input without recording. * Export Multiple - new feature that lets you export multiple files at once, either by track, or split based on labels. * Attempt to automatically correct latency in full-duplex recordings. (This does not work perfectly, and is not yet supported on all systems. It will improve in future versions.) * Fixed a serious bug that could cause data loss when you save and then reload and re-edit an Audacity project containing repeated or duplicate data. * MP3 tags dialog will only pop up the first time you export as MP3; after that it will not pop up again as long as you have filled in at least one tag. * You can now add a label at the current playback position - in the Project menu, with a shortcut of Ctrl+M. * Clicking on a label now selects all of the tracks, making it easier to use the label track to recall selections. * Windows: Fixed a crash in the Time Track "Set Rate" command. * Fixed a bug that caused problems with recordings over 45 minutes on some Windows systems. * Mac OS X: Improved support for the Griffin iMic by fixing a bug that was causing it to always record in mono instead of stereo. * Added support for Software Playthrough (listen to what you're recording while recording it, or while monitoring using a VU meter) - this makes it possible, for example, to record using one audio device while listening to it play through a separate device. * Unix/Linux: Fixed freeze caused by captured mouse when audio device hangs. (Audacity may not respond, but it will no longer freeze all of X.) * Fixed a cosmetic bug that caused improper waveform display if you tried to open an Audacity project saved on a different platform (e.g., copying a project from a Mac to a PC). * Fixed bug that could cause instability when pasting, splitting, or duplicating a label track. * You can now change the font of a label track by choosing "Font..." from the label track's pop-up menu. * Basic printing support has been added. Currently it scales the entire project to fit exactly on one page. Try printing in landscape orientation for best results. * Mac OS X and Windows: Audacity ships with a newer version (1.0.1) of the Ogg Vorbis encoder. Vorbis compression will now have higher quality and smaller file sizes. * Fix a bug that occasionally caused crashes when applying effects to split tracks. * Zoom In / Zoom Out now properly disable when they're not available. * Fixed disk memory leak in Preview * Other minor bug fixes and performance improvements. Changes in 1.2.1: * The following translations have been added or updated: Finnish, French, Hungarian, Italian, Japanese, Norwegian, Polish, Russian. * Fix a bug that could cause data to be lost when pasting audio from one project into another, after the first project has been saved and closed. * Fix a possible crash when opening or resizing the Equalization window, especially when using large system fonts. * Don't allow percentages less than -100% in Change Pitch/Speed/Tempo effects (fixes a possible crash). * Fix a crash when the temporary directory is not available on startup. * Correctly load ID3 tags saved in Audacity project files. * On Linux and OS X, store lockfiles in the temp directory instead of the user's home directory. This fixes problems in lab environments where users have restricted or network-mounted home directories. * Fix a bug that prevented Nyquist effects from running when certain regional settings were activated. * Fix a bug in the Quick Mix command that could cause old temporary files to not be deleted. * Linux: Fix endianness problems in playback on PowerPC. * Linux: Fix compilation problem in Nyquist on MIPS. * Linux: Include a more recent PortAudio v19 snapshot (fixes compilation problems when building with the --with-portaudio=v19 option). * Two new Nyquist plug-ins: "Cross Fade In" and "Cross Fade Out." * Other minor bug-fixes. Changes in 1.2.0: * New cross-fade effects. * Fix problem where samples were drawn in the wrong position when zoomed all the way in. This caused the drawing tool to move a different sample than the one under the cursor. * Don't use id3v2.4 tags, which are not yet supported by most players. (This was fixed in 1.2.0-pre2, but appeared again by accident in 1.2.0-pre3.) * Correctly display translated messages in the status bar. * When the cursor is on-screen, the Zoom In button now zooms to the area around the cursor. * Mac OS X: Fixed audio problems on the Apple PowerMac G5. * Linux/ALSA: Work around a bug in ALSA's OSS emulation that caused Audacity's playback cursor to move too quickly. * Microsoft Windows: The Audacity source code should now compile out of the box on Windows. * Many new/updated translations. Changes in 1.2.0-pre4: * Fixed problems that could occur when importing certain non-seekable PCM audio files, such as GSM610. * Fixed bug that was causing the samples to shift off-screen horizontally when zoomed in very far and the track had a time-shift offset. * Fixed bugs in the new resampler that added noise to resampled audio on some systems. If you experienced noise when exporting to a WAV, MP3 or OGG file you may have been bitten by this bug. * Fixed bug that led to occasional crashes when using the time-shift tool in conjunction with high zoom factors. * Dithering is now only applied on export when it is really necessary (e.g. when converting float samples to 16-bit). * Files that only contain mono tracks are now automatically exported to stereo files when they contain tracks which are panned to the left or the right. * The Delete key can now be used to delete the current selection, in addition to the Backspace key. * Fixed bug where Audacity didn't ask whether to save changes if you close the project or exit while recording. * Mac OS X: Supports Playthrough (listen to what you're recording while recording it) if your hardware device supports it. * Mac OS X: Audacity is now a package (you can right-click on Audacity.app and select 'Show Package Contents'). Launch time has improved significantly. * MS Windows: Fixed problem that caused Windows XP to use the short name of a file ("TESTFI~1.AUP"), which led to problems when the file was later opened again using the long file name. * MS Windows: Fixed bug that caused file exports to fail if the destination directory was the root folder of a Windows drive. * MS Windows: Audacity's application information which is written to the Windows registry now always contains the full path to the executable. * MS Windows: Fixed problems in trying to set the Windows registry as non-admin user, for file-type associations. * Make sure the "Save" command is enabled after changing gain and pan sliders. * Updated translations. Added translator credits to the "About" window in localized versions. Changes in 1.2.0-pre3: * Fixed bug where Export is grayed out when nothing is selected. * Fixed crash caused by opening Audacity on a computer with a high-end sound card with no mixer support. * Fixed crash in Import Raw. * Fixed New Stereo Track. * Cosmetic fixes for Mac OS X. * Support for the VST Enabler on Windows added. * Fixed crash if you close Audacity while the Preferences dialog is open. * Fixed duplicate-character bug in Mac OS X Label Tracks. * The recording level control on Linux now adjusts the IGAIN, rather than the playthrough level of the recording source. * Fixed bug that caused corruption to 16-bit stereo recordings. * Fixed bug that caused data loss if you deleted all tracks in a saved project and then open a new file into the same window. * Added support for alternate audio button order (in Interface preferences) * Added preliminary support for wxX11 * Added fully transparent Windows XP icon * Fixed crash if you try to record (or play) and no audio devices exist, or if the audio device doesn't support the mode you selected. * Audacity no longer sets the process priority to high while recording on Windows. Users can still do this manually using the Task Manager. * Fixed bug that caused last ~100 ms of the selection to get cut off on Windows. * Fixed FFT Filter and Equalization effects dialogs. * Fixed bugs in Unix build system (DESTDIR in locale directory, choosing libsamplerate instead of libresample) * Support for LADSPA plug-ins on Windows added, and three open source LADSPA plug-ins ported to Windows (GVerb reverb, SC4 compressor, and Hard Limiter) Changes in 1.2.0-pre2: * Online help completed. The full manual is nearly complete and will be posted to the web site for online browsing shortly. * Audacity will no longer let you do unsafe editing operations while playing or recording. This eliminates many potential crashes. * Fixed ability to cancel Quit button. * New resampling library, with no restrictions on the maximum or minimum rate of resampling. * Audacity now supports LADSPA plug-ins on all platforms, and supports VST plug-ins through an optional LADSPA plug-in called the "VST Enabler", which you can download separately. Because of licensing issues, Audacity cannot be distributed with VST support built-in. * Mac OS X keyboard shortcut problems have been fixed. * Mac OS X audio muting problems have been fixed. * Mac OS X playback/recording cursor sync problems have been fixed. * Silence now displays a straight line again, instead of nothing. * Added a vertical ruler to the Waveform dB display. * Fixed crash in Change Pitch. * You can now Paste if nothing is selected. * Canceling an Import operation doesn't cause an extra error dialog to appear. * Audacity now handles filenames with international characters correctly. * Now outputs ID3v2.3 tags (instead of ID3v2.4), to be compatible with more MP3 players. * Minor improvements to build system on Unix systems.
