FLAC: same features as WavPack
Hi, I have read this on a forum: 'FLAC supports 24-bit audio fine. My understanding is that the FLAC format also handles 32-bit ints, but the reference encoder does not implement it, and FLAC has no support for float data. WavPack handles all integer bitdepths up to 32-bit and also 32-bit floats. Both codecs handle all sampling rates.' I was wondering if there are plans to support

[opus-tools] [PATCH] Add channel-mapping argument to force channel mapping
This patch adds a new option "channel-mapping" to opusenc which sets the channel mapping family used by the multistream encoder. Please let me know whether adding this option is worthwhile and whether the help string is okay. I tried to keep it short but accurate. The error message for an unimplemented channel mapping is "Error cannot create encoder: request not implemented".

Try using WavPack, http://www.wavpack.com/ This can losslessly compress 32-bit floating point WAVE-EX files, and faithfully preserves every chunk (which FLAC does not do). It is also free.

FLAC 24 bit test results
Thanks to those who sent in results for the 24 bit FLAC test I created. Results were received for Windows, Linux, and Intel Mac. All results showed the identical poor compression ratio with the given test file. This indicates that the issue is likely not related to a certain platform/compiler. I also tested FLAC with various other options like integer only and turning off ASM optimizations (to

Is FLAC hardware independent?
Dear list, > Which "output file" are you referring to?? Also, your question is incompletely specified, because you do not qualify whether the input is the same when you expect the output to be the same. My question is the following: For any encoding option (e.g. -5, default), does the flac encoder produce the same byte-for-byte output regardless of the CPU? Regards, Fernando

Is FLAC hardware independent?
> PS: Here is the answer of David Bryant, the developer of WavPack: "The WavPack codec is hardware independent; the standard "C" encoder will produce the same byte-for-byte output regardless of the CPU it is running on (assuming a properly working C compiler, of course)." The same is true of flac, as long as you're using the same version of the encoder, right? The same

Re: FLAC: same features as WavPack
Hello FLAC list. As far as I know 24 bit FLAC support is broken. It often doesn't compress the audio at all, but instead stores the chunks as verbatim type (although the FLAC format supports 24 bit). Perhaps this is fixed? If so, do let me know. I agree that perhaps 32 bit float/pcm isn't entirely necessary when it comes to storing different qualities. But when wanting to preserve

Is FLAC hardware independent?
Dear list, We are investigating about some state-of-the-art lossless audio codecs and their performance in terms of? rate and compression ratio. Therefore, it is very important to us to know whether a codec is hardware independent, i.e. if it produces the same output file regardless of the hardware. Could you please tell me whether FLAC is hardware independent? Thank you very much in advance.

Support for ultra-high sample rates?
Isn't the FLAC encoder 'tuned' for the compression of audio data at common sample rates anyway? Does it make sense to use FLAC to compress arbitrary analog data at very high sample rates as opposed to other general purpose compression algorithms?

Looking for users of --keep-foreign-metadata
Hi all, Currently I'm looking for users of the --keep-foreign-metadata feature of FLAC. There has been some improvement of this feature in FLAC 1.4.0. Since 2007 there has been a warning in FLAC that --keep-foreign-metadata is a new feature. I think removal of this warning is long overdue, but there are still some issues surrounding it. So, if there are users of this feature on the mailing

--keep-foreign-metadata question
Not sure if this belongs here or in flac-dev. I am subscribed to both, so flop it over if fits better over there. Looking at the Changelog for FLAC 1.2.1 (17-Sep-2007), it says: "With the new --keep-foreign-metadata in flac, non-audio RIFF and AIFF chunks can be stored in FLAC files and recreated when decoding." Where can I find more detail on what is a
