Hi all, I just noticed this: https://sourceforge.net/p/flac/feature-requests/91/ a request for support of 32 bit audio data. The request has been around since 2008. Had two inial impressions: * Would adding this break brackwards compatibility too badly? Obviously decoding of 32 bit

FLAC doesn't support floating point PCM, ADPCM, DSD,... Also it doesn't support more than 8 channels. So I don't understand the statement that > Flac should support available formats. ___ flac-dev mailing list flac-dev@xiph.org

At least on some Japanese online music stores 32bit WAV files are already commonly sold, example http://ototoy.jp/_/default/p/50962 On this website they're always 32bit floats or 24bit ints, though, no idea how realistic float support is. My personal opinion is that having compression for this

Martin, Yes, this is nuts. First, 24-bit is already overkill, as there is no hardware (ADC or DAC) that can handle more than 120dB of dynamic range anyway. There probably never will be hardware that can handle the full 24 bits, because at this point that hardware is already pushing the
