Is FLAC sample a signed or unsigned integer. 2019-12-04 18:55:39 A basic question I'm afraid! Wikipedia https://en.wikipedia.org/wiki/FLAC says QuoteFLAC supports only integer samples, not floating-point (signed/unsigned?). It can handle any PCM bit resolution from 4 to 32 bits per sample, any sampling rate from 1 Hz to 65,535 Hz in 1 Hz increments or from 10 Hz to 655,350 Hz in 10 Hz increments, and any number of channels from 1 to 8.It doesn't say whether these integers are signed or unsigned though, and I can't find the information anywhere else. Is there a choice, if not which is it?
