Probably not. I know that Josh at some point added a second residual coding method (rice2) to support 24-bit, but that only broke backward compatibility for 24-bit files back then. > * This is nuts. 24 bits has a dynamic range of ~140dB which is roughly > the difference between a quiet whisper in a quiet room, to the sound > of a jet engine at 10 meters. Surely that is enough? 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 boundary of thermal noise. Second, most 32-bit material is 32-bit float, and that is something the FLAC format can't handle. I really wonder why anyone would have 32-bit integer material anyway. _______________________________________________ flac-dev mailing list flac-dev@xiph.org http://lists.xiph.org/mailman/listinfo/flac-dev
