Independent encoder implementation available: ffmpeg.Hardware support ( iPod, AirPort Express).Open source (encoding and decoding via FFmpeg and CUETools, decoding only via a standalone decoder).These are the most popular lossless codecs, in alphabetical order:ĪLAC is a codec developed by Apple and used across their hardware and software platforms. So, lower is better.Ĭ Error handling means that a codec can detect a corruption (flipped bit) in a file and warn the user about it, but it will still decode the rest of the file.ĭ The official Monkey's Audio decoder does not support decoding through errors, but this may be achieved with FFmpeg or Winamp, though likely not, when the "Insane" preset is used.į Unofficial (but properly working) open source decoder is available as part of ffmpeg Note: for latest comparison of lossless compression, scroll down to the Links section of this page.Ī Speed and Compression are based on each encoder's default settings and taken from the last CDDA results of this comparison.ī The Compression ratio is compressed size/uncompressed size * 100. 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.
En fin, this is not a matter worth getting too worked up about. Someone wanting portable support would use FLAC or ALAC, and so on. Another user, looking for the very highest compression available, would go with OptimFROG. Some people take into consideration only compression performance when choosing a codec, but as the following table and article shows, there are several other features worth taking into consideration when making a choice.įor example, users wanting good multiplatform compatibility and robustness (e.g., people sharing live recordings) would favour WavPack or FLAC. Given the enormous number of lossless audio compressor choices available, it is a very difficult task to choose the one most suited for each person's needs.
