...mb(=Rice?) encoding: http://en.wikipedia.org/wiki/Golomb_coding#Simple_algorithm What is unclear to me is how many audio samples encoded with a fixed parameter (denoted 'M' in the wiki, which i presume is equivalent to the 'Rice parameter' invohed here): http://flac.sourceforge.net/documentation_format_overview.html But things are a bit more complicated because the wiki says: "audio codecs [...] use a Rice code after the linear prediction step". But it does not tell us about how many points/samples get interpolated, and what criteria are used. So i guess that in the end, for every frame, 2 poi...

Hi, Is there some documentation available about the algorithms FLAC uses? I'm talking about some high-level descriptions of the algorithms, which I can read without having to understand the source code. thanks in advance -------------- next part -------------- An HTML attachment was scrubbed...

I'm misleading about FLAC subset constraints... Please help me understand exact FLAC subset limitation.

Hello FLAC-dev, Do you know if there is some good educational documentation showing FLAC's internal design in a few steps, like this doc for monkeysaudio : http://www.monkeysaudio.com/theory.html If not, what is the principle of the algorithm in a few big steps (example : 1. Conversion to mid/side instead of L/R channels 2. Predictor 3. Entropy coding) ? Best regards. --------------

is it on a per subframe basis, and if so, is each frame padded if it’s not a multiple of 512 bits? or do I have to decode all the data, and run it over the decoded file at once?

...that conform to the standard"... If that's the case then the highest -l value one can 'portably' use would be 12? FWIW, I've tried 16 & 12 and noticed no difference in exhaustive's execution time. Another "nit" I noticed, from http://flac.sourceforge.net/documentation_format_overview.html in the inter-channel-decorrelation section -- it mentions -m vs. -M, where -m always uses mid+side channel whether it is bigger or not, while -M adaptively uses mid+side or stereo depending on which is better. Why would flac levels 7 and 8 use -m (always when -M allows adaptive encoding base...
