Modplug Plugin for XMMS v2.0 / libmodplug v0.8.5 Based on the ModPlug sound engine by Olivier Lapicque <email@example.com> XMMS plugin by Kenton Varda <firstname.lastname@example.org> Maintainer is now Konstanty Bialkowski <email@example.com> Olivier Lapicque, author of Modplug, which is arguably the best quality MOD-playing software available, has placed his sound rendering code in the public domain. This library and plugin is based on that code. For more information on libmodplug, the library for decoding mod-like music formats, see libmodplug/README. Contents -------- 1. Requirements 2. Features 3. Options 4. Troubleshooting --------------- 1. Requirements --------------- - POSIX OS (Linux or other unix*) - XMMS 1.0.0 or higher (only for modplug-xmms plugin). * This library is only guaranteed to work on Linux. I have received conflicting reports on whether or not it will work on Solaris x86. One person reported that the plugin compiled fine with the "-fpermissive" compiler flag, which I have added. Others had far more trouble. Note that a recent change to the library should allow it to work on PPC and other big-endian systems. * Under linux there is also modplugplay contributed, which allows command line playing of mod files under Linux. ----------- 2. Features ----------- - Plays 22 different mod formats, including: MOD, S3M, XM, IT, 669, AMF (both of them), AMS, DBM, DMF, DSM, FAR, MDL, MED, MTM, OKT, PTM, STM, ULT, UMX, MT2, PSM - Plays zip, rar, gzip, and bzip2 compressed mods. The following extensions are recognized: zip: MDZ, S3Z, XMZ, ITZ rar: MDR, S3R, XMR, ITR gzip: MDGZ, S3GZ, XMGZ, ITGZ You can also load plain old ZIP, RAR, and GZ files. If ModPlug finds a mod in them, it will play it. Note: To play these formats, you need to have the associated decompression utilities (unzip, gunzip, unrar) installed. Note(2): The format of the mod is NOT determined from the extension on compressed mods. For example, if you zipped a UMX mod and gave it the extension MDZ, it would work fine. - plays timidity's GUS patch files (*.pat): a multi sample pat file with n samples can be played with a Frere Jacques canon with n voices. - plays all types of MIDI files (*.mid): uses the timidity .pat files for samples (when available) recognizes environment variables: MMPAT_PATH_TO_CFG set to the directory where the file "timidity.cfg" and the subdirectory "instruments" can be found, default: "/usr/local/share/timidity". MMMID_SPEED for experimenting with the mod speed (1 thru 9) MMMID_VERBOSE for feedback on the conversion process MMMID_DEBUG for sake of completeness, only useful for maintainers - plays textfiles written in the ABC music notation (*.abc): uses the timidity .pat files for samples (when available) recognizes environment variables: MMPAT_PATH_TO_CFG set to the directory where the file "timidity.cfg" and the subdirectory "instruments" can be found, default: "/usr/local/share/timidity". MMABC_NO_RANDOM_PICK when not set and the abc file contains multiple songs (X:n) the first song to be played will be picked at random another click on the play button advances to the next song in the file (or the first when the last song has been played), when set it can be 0 (zero) or not numeric to let it play all songs in the file, a positive number n to let it play the n-th song in the file, a negative number -n to let it play the n-th song in the file and advancing to the next song when the play button is clicked. MMABC_DUMPTRACKS when set it gives diagnostic information on stdout, values can be: all - every event is printed nonotes - only the control events (looping, breaks etc.) are printed any other value prints the control events and every note event immediately succeeding the control events. - Slightly better sound quality than Mikmod. Vastly superior quality over Winamp. - All XMMS calls are supported exept for the band gains on the equalizer. The preamp is supported, but MOD music is not anywhere near as cheap to equalize as MP3. Thus, equalization does is not supported in this version. However, a variable bass boost option is available in the configuration dialog (see below). - Tons of playback options (see below). ---------- 3. Options ---------- All of the following items are configurable from the plugin configuration dialog box. Sampling rate: Higher is better. Note that the sound is rendered at a higher sampling rate and converted down to increase quality. Bits per sample: 8-bit or 16-bit sound. Note that all computations are done at 32-bit and converted down to the sampling rate you specify. Channels: mono/stereo. Note that all computations are done in stereo. If you choose mono, the channels will be mixed. Resampling: Method used to convert samples to different sampling rates. "Nearest" is the fastest setting (but sounds terrible), while "8-tap fir" is the best-quality setting. Noise Reduction: Reduces noise. :) Fast Playlist Info: When this option is on, names of songs in your playlist will load considerably faster, but song lengths will not be shown and only MOD, S3M, XM, and IT formats will have their names shown. Don't worry, though, because all the data which is skipped will still be loaded when you actually play the song. This should probably always be on. Reverb: A nice reverb effect. The depth and delay of the reverb can be tuned to your liking using the sliders. Bass boost: Variable bass boost effect. The "range" slider controls the frequency range of the bass boost. If you increase this value, higher frequencies will be boosted, but the overall volume increase will be less. (you can compensate by using the volume slider:) Surround: Dolby Pro-Logic surround effect. Depth and delay can be fine tuned. Preamp: A global volume boost. Note that setting the preamp too high will cause clipping (nasty clicks and pops). Looping: Some mods have loops built-in. Normally, these loops are ignored because otherwise the same mod would play forever. However, you can choose to respect the loops, or even set a number of times to follow a loop. ------------------ 4. Troubleshooting ------------------ Problem: None of the config options seem to have any affect on the sound quality. Possible cause: You did not disable MikMod, so mods are being played by it rather than by ModPlug. Solution: Disable MikMod in the XMMS input plugins configuration dialog. Alternative cause: You are not playing a mod-like file. ModPlug only plays mod-like file formats, and has no affect on mp3's or other non-mod formats. (Note: Yes, I have actually had people e-mail me with this problem.) Solution: Download some mods. You can start at <http://www.traxinspace.org>. Problem: Some of my files load up, but show garbled info in the playlist and/or don't play correctly. Possible cause: The mod is in a different format than its file format suggests. Modplug-XMMS uses a combination of file extension and contents to figure out what format a mod is in, and can be thrown off if a mod is incorrectly labeled. Solution: Turning off "fast info" in the configuration may fix the problem. This will cause Modplug-XMMS to detect all basic mod types by content, but archive types will still be detected by extension. If this doesn't solve the problem, then you probably have files which are actually compressed archives but are not labeled as such. For example, you may have a file "aws_anew.xm" which is actually a ZIP archive. You will have to either unzip these files or rename them to have an extension associated with their type. In the case of a ZIP, you can use any of the extensions "ZIP, MDZ, S3Z, XMZ, ITZ". (Note that these five types are all treated exactly the same -- the actual format of the mod is detected by contents.) Problem: Everything appears to be working, but no sound is being generated. MP3's play just fine. Possible cause: Modplug has a relatively low default volume, and you may just not be hearing it. (Note: Yes, more that one person has e-mailed me with this problem.) Solution: Turn up your volume. You may wish to do this via the "preamp" setting in the ModPlug configuration. This way, you won't have to turn down your volume again when you play an MP3. Problem: You have a mod which is rendered incorrectly by ModPlug-XMMS. Possible cause: This could be our fault. :) Solution: First, test the mod using the Windows version of ModPlug, if you can. If it sounds wrong there, then send the mod and a bug report to Olivier Lapicque <firstname.lastname@example.org>. If the mod plays correctly in Windows, however, then the bug is my fault. In that case, e-mail me (Konstanty) <email@example.com>. (previously Kenton Varda at <firstname.lastname@example.org>). Problem: I have a problem which is not listed here, or an idea for a cool feature. Solution: E-mail me (Konstanty) at <email@example.com>. I would be happy to hear any suggestions or problems you have.
