Its interesting that you didn't see any differences between flac and opus, as opus has a hard 20 kHz low-pass filter and is 48kHz-only.
- diimdeep 5y agoThere is visible 20 kHz LPF, but it is meaningless for use case of music listening, right ? I did not liked degradation at 140-128kb/s and noise above 16kHz and some artifacts 10-16khz that is clearly visible and much more impactful.

- rokweom 5y agoAs I said, spectrograms are not indicative of compression quality. Codecs should be judged by ears only. What you see in a spectrogram will vastly differ between codecs and will not reflect their compression efficiency.
