Quote from: rari_teh on November 27, 2021, 05:02:57 AMYou thoroughly misunderstood what I said. The American dub has a higher bitrate, but is mastered in mono. The Japanese dub has a lower bitrate, but is mastered in stereo. Both the bitrate and the number of channels affect the quality of the audio, the more the better. Which out of the two dubs has better quality audio is debatable – one is binaural, but has lower fidelity; the other has higher fidelity, but the sound is flattened to one single channel. To inject the low-fidelity stereo Japanese audio into the American video that's expecting a single high-fidelity mono soundtrack, one would have to either A) fiddle with the binaries to instruct it that the audio is now low-fidelity stereo, or B) turn the low-bitrate stereo track into a high-bitrate mono track. Sadly, definition is limited by the weakest link in the chain: transcoding a low-bitrate audio file into a higher bitrate does not improve its quality, the same way that opening a JPEG on Paint and saving it as PNG doesn't magically do away with the artifacting. To get a true high-bitrate mono Japanese track, I would need to have access to the lossless (or high-bitrate) masters, which naturally were never released to the public. The result of this bad transcode would be a track that's both mono and effectively low-bitrate, because every second sample of the now technically higher bitrate would be repeated, which would be, yes, considerably lower quality than before, as in practice the bitrate stayed the same and one sound channel was lost in the flattening.
