[flac-dev] Exact FLAC subset constraints

I'm misleading about FLAC subset constraints... Please help me understand exact FLAC subset limitation. From https://www.xiph.org/flac/documentation_tools_flac.html#flac_options_blocksize: Subset streams must use one of 192/576/1152/2304/4608/256/512/1024/2048/4096 (and 8192/16384 if the sample

I mean that the first statement [Subset streams must use one of 192/576/1152/2304/4608/256/512/1024/2048/4096 (and 8192/16384 if the sample rate is 48kHz).] published on https://www.xiph.org/flac/documentation_tools_flac.html#flac_options_blocksize page IS NOT EQUAL to second statement [The

[flac-dev] Why Rice order in --best switch is limited to 6?

2014-01-07 Thread Барт Гопник
The --best switch currently synonymous with -8 that synonymous with --compression-level-8 that synonymous with -l 12 -b 4096 -m -e -r 6. Why value of -r switch in --best is limited to 6? The maximum Rice order is 8 (not 6) for the stream to be Subset compatible. -r 8 (-l 12 -b 4096 -m -e -r 8)

Finally, does this mean that: 1. Now any block size from interval [16, 4607] is subset, e.g. 588? 2. Now any block size from interval [16, 16384] is subset, (only) if sample rate 48 kHz? And the third is the most interesting question: 3. Now not only constant (fixed) block size stream can be

check the resulting file for subset blocksizes, sample rates, bits per sample, LPC filter order and rice partition order. That's all parameters that I need to check? FLAC tools have a lots of warnings about non-subset files during encoding, but unfortunately don't have easy way to check/test

My portable audio player starts to stutter mildly when files have LPC blocks with a order larger than 12, but I'm not sure it will play files with very large blocksizes or unusual samplerates at all. Can you name model of your portable audio player please?
