Would variable bit-depth for OPUS (à la LossyWAV) be technically possible? 2018-05-07 21:31:45 I feel like I'm possibly asking a stupid question, since I don't know if this method for reducing bitrate is technically only applicable to lossless codecs.I've been playing around with LossyFLAC / LossyWav and the results are impressive. I can get my original FLAC files down to less than half their original bitrate while maintaining perceptual transparency. This is achieved by intelligently reducing bit depth and shaping the resulting noise so that is inaudible, while keeping all the detail intact. https://wiki.hydrogenaud.io/index.php?title=LossyWAVIf I'm not mistaken, OPUS does not currently affect the bit depth of samples, and uses other means to efficiently encode audio.My question is this. Can OPUS, in principle, implement this kind of method (perhaps as an extra setting) to further reduce the bitrate while maintaining a certain quality level? That would be an amazing addition IMO but I'm just unclear as to whether it can be done - whether it is at odds which how OPUS actually works at a basic level.By the way, you can try out LossyWAV by searching "LossyFLAC GUI". Nifty program.
