Err, I would expect quantization/reconstruction/... to always create noisy bits, even if on the LSB and very seldom. Otherwise it is virtually lossless. Otherwise the noise is on the 4th LSB and it means the output is effectively scaled. Are you sure it's not just a convenience to output the more practical, aligned 24bits? Like something in the bitstream actually indicating "shift left 4 bits", and the audio is *actually* 20 bits? You probably know better than me, but I can't make sense of that. -- Christophe _______________________________________________ libav-devel mailing list [email protected] https://lists.libav.org/mailman/listinfo/libav-devel
