Revision as of 03:46, 16 April 2005

Given the enormous amount of lossless audio compressor choices available, it is a very difficult task to choose the one most suited for each person's needs.

Several people only take into consideration compression performance when choosing a codec. But as the following table and post shows, there are several other features worth taking into consideration when making that choice.

For example, users wanting good multiplatform compatibility and robustness (E.G, people sharing live recordings) would favour WavPack or FLAC. Another user, looking for the very highest compression available, would go with OptimFROG. Someone wanting portable support would use FLAC or ALAC, and so on.

En fin, this is not a matter worth getting too worked up about. If you later find out the codec you chose isn't the best for your needs, you can just transcompress to another format, without risk of losing quality.

* Encoding speed, Decoding speed and Compression ratio are based on each encoder's default settings.

** Flexibility refers to the amount of encoding choices offered to the users (Fast/low compression, Slow/high compression and everything inbetween)


These are the most popular lossless codecs, in alphabetical order:

==ALAC - Apple Lossless Audio Codec== http://www.apple.com/itunes/import.html

ALAC is a codec developed by Apple for usage in iPod and AirPort Express.

ALAC PROS

  • Very fast decoding
  • Open source (decoding only)
  • Hardware support (iPod, AirPort Express)
  • Streaming support
  • Tagging support (QT tags)
  • Excellent hardware-software-lossy format integration with iTunes/iPod.

ALAC CONS

  • Closed source (encoding)
  • Few software support (iTunes)
  • Doesn't support multichannel audio and high resolutions
  • Compression efficiency not on par with other lossless codecs
  • No hybrid/lossy mode

ALAC Other features

  • Fits in the MP4 container
  • Can be used with the AirPort Express gadget

==FLAC - Free Lossless Audio Codec== http://flac.sourceforge.net/

FLAC is a lossless codec developed by Josh Coalson. It's part of the Xiph multimedia portfolio, along with Ogg Vorbis and Theora.

FLAC PROS

FLAC CONS

  • Relatively slow encoding
  • No hybrid/lossy mode
  • Doesn't support RIFF chunks

FLAC Other features

  • Supports embedded CUE sheets (with limitations)
