Hi folks, I'm trying to get a handle on the many lossless audio formats from the perspective of a software developer. I love the FLAC format because it is open source and it performs very well. But there is also the MLP (Meridian Lossless Packing), AAC (Apple Lossless), and probably some Microsoft format(s) that compete in the same feature set....

Oops, I was a bit sloppy in my organization, and also sloppy on a few facts. I did not intend to imply that A-52 was lossless - I was merely using it as an example of an open specification format that cannot be implemented and sold without being licensed. I'm glad that we are finally getting lossless formats accepted in large public standards. The liba52 library may not be legal. I seem to recall some legal...

First off, I'm not an expert in this field, but I thought I could probably answer a few of your questions. If anyone else wants to give a more complete explanation, please do.

I know this probably transcends the scope of the current aims of Ogg video, but one thing I'd consider extremely useful is a lossless video compressor. There are a few of them out there (e.g. PICVideo's lossless wavelet codec) but I've found no free ones so far. The primary use would be for storage of video clips that would be too cumbersome to store as raw frames but still require some processing (e.g. storing clips to...

Hello, I noticed that kbps jumps quite high in -q 10 mode and is nearing lossless compressors. Would it be a difficult task to make OGG a lossless compressor at -q 10? I don't know much about lossy/lossless compression internal logic, so excuse me if my question is out of place. But this would be a really nice feature that would make OGG an "all in one" tool. Ch...

Hi, has the subject of creating a lossless video codec been considered? I know Dirac is available, but it is a hybrid; saving a file and having to set a compression setting is not very intuitive for a novice. I suggest a lossless codec for the distant future, an idea of the codec's name is: FLAV. Free Lossless Agile Video. The go...

Any way to setup a lossless stream from MPD? I know MPD can encode FLAC, but I don't know if Icecast can handle it. Any other lossless options? -------------- next part -------------- An HTML attachment was scrubbed... URL: http://lists.xiph.org/pipermail/icecast/attachments/20150422/72a1c4d4/attachment.htm

Hi All, It is possible to make Opus/CELT a lossless coder if I allow a sufficiently high bit rate? We considered using FLAC, but FLAC's latency is well beyond the acceptable range.

...tly. In it he says that Vorbis uses MCDTs <sp> and that these are theoretically reversable. And now, I learn that theoretically we can use bitrate peeling to make smaller files from larger ones, and that leads to my question. Could I theoretically compress my CDs to Vorbis at a rate that is lossless, and then be able to peel those files to 128k/s or lower for a portable device? This would alow me to have archive quality music at home, and lower quality on the go, without recompressing, or storing two versions of each song, one protable and one archive quality. Jason PS - Thanks for Vorbis, i...

Monkey's Audio lossless compressor (currently win32 only, free but not open-source except decoder) author is thinking to implement a kind of audiophile-quality lossy compression which would filter "noise bits" that are hard to encode lossless but which are (or should be) inaudible and thus improve lossless compr...

Windowing may seem like a good idea, but remember that your decoder will have to recreate every step that your encoder uses so that it can be undone.

...had some work in VQ on speex i.e. modifying split VQ to GMM based parametric VQ and I thought If I train the GMM based VQ codebooks with audio signal and then do audio coding with speex, I probably get a better(smaller) residual signal even with speex. But I couldnt get that. I was trying to get a lossless bitstream by MUXing the speex-bitstream and the entropy encoded error signal from speex. I still have 2 months time but I need to do some useful and fundamentally strong work(even if its a small improvement). I can work day and night, But want to come up with some results. Results could be anyt...

Is FLAC a variable bit rate format when streamed? If so, how can it be truly lossless? -- Dennis Brunnenmeyer Director of Engineering CEDAR RIDGE SYSTEMS 15019 Rattlesnake Road Grass Valley, CA 95945-8710 Office: 1 (530) 477-9015 Mobile: 1 (530) 320-9025 eMail: dennisb /at/ chronometrics /dot/ com http://www.chronometrics.com/crs/index.html <http://www.chronometrics.com/crs/i...

the audio was also 192,000khz sample rate, forgot to mention that, adn here are the audio files, the original, the flac, and the decoded from flac. the archive is 7zip, Idk where to upload it so I'll just send it to depositfiles. http://depositfiles.com/files/90anghniw -------------- next part -------------- An HTML attachment was scrubbed...

Hello, What is nowadays lossless compression's limit (tested on a large library of music samples, because of course, it depends on the music we do the tests on) ? I often see 53% - 62% of original WAV file's size. ( https://xiph.org/flac/comparison.html ) Are there algorithms that can losslessly compress to, say 40% of o...
