X Lossless Decoder 20070728

X Lossless Decoder(XLD) is a tool for Mac OS X that is able to decode/convert/play various lossless audio files. The supported audio files can be split into some tracks with cue sheet when decoding. It works on Mac OS X 10.3 and later.
XLD is Universal Binary, so it runs natively on both Intel Macs and PPC Macs.
XLD supports the following formats:
• (Ogg) FLAC (.flac/.ogg)
• Monkeys Audio (.ape)
• Wavpack (.wv)
• TTA (.tta)
• Apple Lossless (.m4a) [10.4 only]
• AIFF, WAV, etc
Other formats supported by Libsndfile are also decodable. XLD uses not decoder frontend but library to decode, so no intermediate files are generated. All of the supported formats can be directly split with the cue sheet. XLD also supports so-called embedded or internal cue sheet.
Currently you can choose output format from WAVE,AIFF and Raw PCM. In addition, you can choose Ogg Vorbis (aoTuV), MPEG-4 AAC (QuickTime/CoreAudio), MP3 (LAME), Apple Lossless and FLAC in the GUI version.
Frontend and backend of XLD are prefectry separated, so the frontend is able to access the various decoder with the same interface. If we provide plug-in interface in the future, you can easily develop the plug-in of the new format.
If this interests you, please see XLDDecoder.h in the source files.
Enhancements:
- Updated FLAC to version 1.2.0
- It will be slightly faster on Intel Macs due to enabling MMX/SSE codes.
- Partially rewritten Monkeys Audio/TTA decoder with SSE optimization
- Notes: TTA version 3.4.1 has been released, but it has no improvement on decoder and lost 32bit float decoding capability. So XLD still uses version 3.3.
- Fixed overwriting problem when both input and output file have the same name (GUI)
