Questions tagged [flac]

Questions about the FLAC audio format. FLAC is an acronym for Free Lossless Audio Codec. The codec uses a compression scheme that was designed specifically for audio, resulting in a fast, good compression ratio with no loss of quality.

FLAC stands for Free Lossless Audio Codec, an audio format similar to MP3, but lossless, meaning that audio is compressed in FLAC without any loss in quality. This is similar to how Zip works, except with FLAC you will get much better compression because it is designed specifically for audio, and you can play back compressed FLAC files in your favorite player (or your car or home stereo, see supported devices) just like you would an MP3 file.

FLAC stands out as the fastest and most widely supported lossless audio codec, and the only one that at once is non-proprietary, is unencumbered by patents, has an open-source reference implementation, has a well documented format and API, and has several other independent implementations.

See About FLAC for more, or Using FLAC for how to play FLAC files, rip CDs to FLAC, etc.

NOTE: The above was taken directly from the project's website.

Is there any crossbrowser solution for playing flac? (or is it possible in theory to make one)

Not interested in silverlight. Flash/javascript/html5 solutions are acceptable. If you do not know such solutions, could you please say is it possible to make such that or not?
