What’s the rationale for 256 opus? I haven’t followed trends in the anime encoding space for quite a few months. With the new 1.5 ML stuff improving quality for the same bitrate even further doesn’t it make sense to leave it at the usual 128 for TV-tier stereo?

@nph We follow the following equation for Opus bitrates:
128 * ({target_channels}/2.0)^0.75(source).With a base bitrate of 128 because that’s the threshold for transparency for stereo audio (edgecases exist), that equates to:
Opus 1.5 didn’t introduce improvements in the high fidelity range, it improved stuff for very low bitrates, speech and web delivery, as well as some performance improvements.
