Hi, I've tried to find info about unofficial 32bit float support in FLAC, and found several conversations. Most of them were talking about a 24bit limit, but from the manual I guess that this limitation is gone, as it supports up to 32bit integer. So my question is, what would be the best way, or what is a common way to FLAC-encode floating point audio? The first idea is obvious, we have

does there exist anywhere a useful source version of an ACM for vorbis audio? I've seen the binary one somewhere in Japan, and there's an abandoned project at SourceForge, but I'm having a helluva time building it. I know all the caveats about CBR vs. VBR, ACM/AVI problems etc. but I need it anyway. Thanks in advance - ___ Dan Miller (++,) Founder, CTO, On2.com --- >8 ----

...relation would detect matching frames, only at a smaller level. Imagine if you convert a violin sound into a pitch period somewhere in its middle, and the residual from that the subtraction of that pitch period in repeated frames. I think the residual would be rather quiet. > "Didier Dambrin" <didid at skynet.be> wrote: > ... >> I like FLAC on the paper because of its metadata preservation, in that >> riff >> tag, which is critical for my needs. > > Try using WavPack, http://www.wavpack.com/ > > This can losslessly compress 32-bit floating &...

All, Monty has made some improvements to the vorbis reference implementation, and we're ready to do a new release. Please sanity check the release candidate at http://people.xiph.org/~giles/2007/libvorbis-1.2.0rc2.tar.bz2 And let us know if there are any problems. The plan is to make an official release on Wednesday. Changes since the 1.1.2 release: * new ov_fopen() convenience

...marketed as a distinct file type. Perhaps we can somehow make this scenario unlikely, and encourage people to use the proper tools, I dunno. Now we're into the psychology of marketing rather than the capabilities of various API's. - dbm -----Original Message----- From: Dambrin Didier [mailto:gol@image-line.com] Sent: Mon 11/11/2002 10:34 AM To: vorbis-dev@xiph.org Cc: Subject: Re: [vorbis-dev] ACM codec I think it's true for every new audio format.

I'm doing testing on this at the moment. But to start with: >>Because music represents an analog signal, As I wrote, it would only apply to specific genres, not analog recordings. Electronic music quite often doesn't leave a computer these days. And it mainly consists of drums, synths & vocals/effects. Drums are often samples sequenced at sample (not sub-sample) accuracy,
