...;I have some improvements reflected in the attached file vorbis120.patch: 1) Major bug remapping channels. The values in wav_permute_matrix (oggenc\audio.c line 380) must be (instead the commented ones): {0,2,1,3,4}, // {0,1,2,3,4} {0,2,1,4,5,3} // {0,2,1,5,3,4} 2) New feature. Support for WAVE_FORMAT_EXTENSIBLE wav headers with only: if (format.format == WAVE_FORMAT_EXTENSIBLE && len > 25) format.format = READ_U16_LE(buf+24); 3) New feature. Support wav files 32 bits int. 4) New parameter --ignorelength. To support wav files > 4 GB or STDIN with datalength ignored." "...

Hello, I created a patch for oggenc that gives it minimal support for WAV files with the WAVE_FORMAT_EXTENSIBLE format. What's the right way to submit this? http://www.microsoft.com/whdc/device/audio/multichaud.mspx Joe Holt

...several possibilities on page 27. DTS-HD seems to specify 7 different possible 7.1 layouts (http://www.scribd.com/doc/17630423/21/Channel-Layout). I think my preference for the Apple/Core Audio layouts is known but obviously any standard would be better than none. Do I understand correctly that WAVE_FORMAT_EXTENSIBLE simply defines a standard channel order and FLAC would specify compatible channel masks? http://msdn.microsoft.com/en-us/library/windows/hardware/gg463006.aspx hasn't been updated since 2007 so I may have been looking at an old document.

The flac encoder does give a warning during the encoding process: WARNING: legacy WAVE file has format type 1 but bits-per-sample=24 Looking at the specs for WAV files, it appears that for 24-bit files should have their format code set to WAVE_FORMAT_EXTENSIBLE, but these files are still set to WAVE_FORMAT_PCM. Could this be the source of the problem? If not, do you have any other ideas? I can provide example files if wanted. Thanks, Justin

Hi Guys, I've just faced a wrong warning trying to encode a 24 bits WAV file if(wFormatTag == 1) { if(bps != 8 && bps != 16) { if(bps == 24 || bps == 32) { /* let these slide with a warning since they're unambiguous */ flac__utils_printf(stderr, 1, "%s: WARNING: legacy WAVE file has

Hi, I am using vorbis-tools 1.4.0 on Fedora 14 to convert Ogg Vorbis files to MS WAV format. It seems that ogg123 is encoding the wrong AudioFormat value. For Uncompressed PCM, the AudioFormat should be 1 but for some reason, it is being encoded in the WAV file as -1. This used to work on some prior version of either Fedora or vorbis-tools. I thought I'd ask in the email list in case

Hello, and thank you for approaching us.

I will probably use WAVE_FORMAT_EXTENSIBLE instead: "WAVEFORMATEXTENSIBLE allows you to avoid having to register a new format tag with Microsoft." Preroll is supported by ASF. But I'm unsure if pre-skip and end trimming can be supported. I guess one could live without it.

...quently. It isn't clear > what the issue is there? WARNING: legacy WAVE file has format type 1 but bits-per-sample=24? Some of my programs' wav files get that warning, too. I just looked into that, and apparently Microsoft's latest spec urges the use of an alternate header format (WAVE_FORMAT_EXTENSIBLE) for bit depths other than 8 and 16. I'm not sure why, as I know of no program that has trouble with these 24-bit files, and no program besides FLAC that warns about them. Other wave file documentation I've seen -- for example, http://www.sonicspot.com/guide/ -- doesn't include that re...

Hi, >That's what I wanted to say a month ago. Mr. Blum, I'm really sorry for misunderstanding you. My mistake. I choose an ACM codec because it's the only option that works on every Windows Platform, and since the DirectShow has a generic wrapper that allows it to use ACM codecs, it appeared a good idea. I didn't note that the file format was going to be a problem. But I think

Hi all, I recently managed to install "multimedia German dictionary", which I get with the local newspaper , under wine and it works OK. The problem it is when I try to use the most important feature for me - the pronunciation. When I try to listen to any word , no sound is played and wine outputs the following to the console: wodOpen unimplemented format: WAVE_FORMAT_ADPCM I rewieved

...he Waves into to be able to encode them to 7.1 FLAC, or does the reference encoder just not currently support 7.1? I have also tried using the utility called Wavewizard to output the file as plain Wave PCM, but then it gives an error along the lines that there are more then 2 channels and it is not WAVE_FORMAT_EXTENSIBLE, so it cannot assign channels on its own. Most confusing part of all is that someone sent me a 7.1 FLAC sample from a BR movie. For some reason the reference CLI is unable to decode the file even for experimentation. I get the error "Inosensu Kkaku kidtai-sample-track2.ogg: ERROR: stream is t...
