Min and max cutoff frequency
Dear list, Could you please tell me the values of the minimum and maximum cutoff frequencies for each coding version of the 44.1 kHz sampled data? For instance, are the values fmin=100 Hz and fmax=12 kHz valid? Thank you very much in advance. Kind regards, ? Fernando A.

FLAC suddenly compresses more - why?
...n ratio is highly dependent on the encoded wav file. If you are processing CDs, the compression ratio?for rock and pop music?is tipically 45 % to 70 %. For other kinds of music such as jazz, the compression ratio may be from 25 % to 40 %. What kind of music have encoded so far? Regards, Fernando A.

Questions: FLAC performance, compression ratio and extra documentation
...I find more documentation about FLAC format and design? Are there any more documents than those in the FLAC web page? It' d be extremely useful not only for me, but also for many people investigating about this interesting open-source format. Thanks in advance. Best regards, Dr. Fernando A.

Using line spectral pairs for LPC quantization
...fficients, you could design a good non-linear compander in order to minimize the error due to LPC coefficients quantization. By doing this, the input signal would be better estimated and the output residue (which occupies more than 90 % of the output bitrate) would be smaller. Regards, Fernando A.

Is FLAC hardware independent?
Dear list, > Which "output file" are you referring to?? Also, your question is incompletely specified, because you do not qualify whether the input is the same when you expect the output to be the same. My question is the following: For any encoding option (e.g. -5, default), does the flac encoder produce the same byte-for-byte output regardless of the CPU? Regards, Fernando
