I was wondering if anyone has successfully compressed losslessy, 24 bit, 96 kHz stereo audio. I have a project in mind utilizing 24/96, but was unsure as to whether there were any lossless codecs which efficiently compressed these files, or even supported 24/96 at all.

Thanks!

I know that FLAC, LPAC, WavPack, RKAU, and Monkey's Audio all support 24/96 lossless compression. You can find a comparison and links here:

Since I tested this I have read that the new OptimFROG also supports 24-bit data.

Thanks Bryant,

I feel like an idiot. I was under the impression (don't know how) that MAC couldn't handle either 24 bit or 96 kHz. When I tested FLAC, output wasn't matching input which lead me to this forum. Just tested MAC, and it works brilliantly. Given MAC is my preferred lossless codec anyways, I have found the solution to my problem.

Could you please report this in detail, as the FLAC developer also reads this forum. Other people may use FLAC to compress 24/96 and perhaps are not aware of possible bugs.

FLAC is not a generic WAVE file compressor; it doesn't store anything but the audio data. If you have other subchunks in there like 'list', 'cue ' or whatever then the decoded WAVE file will be different even though the audio is exactly the same.

Chances are good that you only care about the audio data anyway, in which case it's not a problem; the other subchunks are just wasting space.

Do they also support more than 2 audio channels?
(MA, FLAC, etc.)

FLAC yes, MA no. I think FLAC and Shorten are the only lossless codecs that support more that 2 channels.
