What this is

This is a fork of sacd-ripper/sacd-ripper. For original release documents, please refer to https://github.com/sacd-ripper/sacd-ripper . This fork focuses only on improvement of sacd_extract, so most of the irrelevant codes have been removed.

This fork adds the following additional features to the original sacd_extract.

1. Padding-less DSF generation (-z): Some players do not handle zero padding in DSF correctly resulting in a pop noise at a track transition. With this option, instead of zero padding, the data fragment that doesn't perfectly fit in the 4096 Bytes/channel block size at the tail of a track is carried forward to the head of the next track so no zero padding is needed. This is a loss-less process. This option cannot be combined with the -t option because continuous processing of the entire album is needed for this option to work.
2. Concurrent ISO+DSF/DSDIFF processing (-w): With this option, both ISO (-I) and DSF (-s) or DSDIFF (-p) can be generated concurrently. This is much more efficient than generating ISO and DSF/DSDIFF sequentially because ISO generation is a very light process in terms of CPU usage while DST decompression (mandatory for DSF, optional for DSDIFF) is not. The run time of this process is expected to be the slower of ISO and DSF/DSDIFF generation.
3. Output directory options (-o and -y): These allow users to specify the output directory. For the concurent processing mode, -o is for ISO and -y is for DSF/DSDIFF. The directories specified by these options must exist. Output directories default to the current directory.
4. Enabled max compiler optimization in CMakeList.txt for gcc. This provides about 3x speed boost to DST decoding (mandatory for DSF generation) for Linux and MacOS.
5. More ID3v2 frames are added. TSRC (ISRC), TPUB (Publisher), TCOP (Copyright message), TCOM (Composer), and TPE2 frames have been added. TPE2 is used as album artist which is a common practice. Also, the fix for ID3 size coding issue contributed by David Bryant has been merged.
6. Mingw-w64 support: This allows compilation of a Windows binary without Visual Studio.
7. A little more aggressive multithreading: Raw read and DST decoding, which used to happen sequentially, are performed in parallel.
8. Stereo and multi-channel extraction in one shot: No longer need to run sacd_extract twice to extract stereo and multi-channel tracks. In other words, the -2 and -m options can be used simultaneously for DSF/DSDIFF generation.

Development of this software is primarily done on Linux. Functionality on Windows has been checked. Windows binary needs to be compiled with Mingw-w64. Visual Studio is no longer supported.

Usage

The following options are available for the sacd_extract commandline tool: :

-2, --2ch-tracks                : Export two channel tracks (default)
-m, --mch-tracks                : Export multi-channel tracks
-e, --output-dsdiff-em          : output as Philips DSDIFF (Edit Master) file
-p, --output-dsdiff             : output as Philips DSDIFF file
-s, --output-dsf                : output as Sony DSF file
-z, --dsf-nopad                 : Do not zero pad DSF (cannot be used with -t)
-t, --select-track              : only output selected track(s) (ex. -t 1,5,13)
-I, --output-iso                : output as RAW ISO
-w, --concurrent                : Concurrent ISO+DSF/DSDIFF processing mode
-c, --convert-dst               : convert DST to DSD
-C, --export-cue                : Export a CUE Sheet
-i, --input[=FILE]              : set source and determine if "iso" image,
                                  device or server (ex. -i 192.168.1.10:2002)
-o, --output-dir[=DIR]          : Output directory (ISO output dir for concurrent processing mode)
-y, --output-dir-conc[=DIR]     : DSF/DSDIFF Output directory for concurrent processing mode
-P, --print                     : display disc and track information

Usage examples

Extract all stereo tracks in uncompressed DSDIFF from an ISO to /home/user/blah/<album_name>:

$ sacd_extract -2 -p -c -i"Foo_Bar_RIP.ISO" -o /home/user/blah

Extract all stereo tracks in padding-less DSF files from an ISO to /home/user/blah/<album_name>:

$ sacd_extract -2 -s -z -i"Foo_Bar_RIP.ISO" -o /home/user/blah

Extract an ISO from a server to /home/user/blah/<album_name>.iso:

$ sacd_extract -I -i192.168.1.10:2002 -o /home/user/blah

Concurrently extract an ISO file to /home/user/blah/<album_name>.iso and all stereo tracks in DSF to /tmp/blah/<album_name> from a server.:

$ sacd_extract -I -s -w -z -i192.168.1.10:2002 -o /home/user/blah -y /tmp/blah

Concurrently extract an ISO file to /home/user/blah/<album_name>.iso and all stereo and multi-channel tracks in DSF to /tmp/blah/<album_name> from a server.:

$ sacd_extract -I -s -w -z -2 -m -i192.168.1.10:2002 -o /home/user/blah -y /tmp/blah
