...nal wav? I am not sure what Audacity means by a logarithmisch sweep. Is that a fixed number of Hertz per second (SoX calls that linear)? Or a fixed number of semitones per second (SoX calls that exponantional)? (The ogg comment says 5s=10Hz, 10s=20Hz, 15s=39Hz, 20s=78Hz, 25s=156Hz, 30s=312Hz, 35s=625Hz, 40s=1.25kHz, 45s=2.5kHz, 50s=5kHz, 55s=10kHz, 60s=20kHz so it seems the frequency rises logarithmically.) $ sox -c 1 -r 96k -b 16 -n /tmp/sweep.wav synth 60 sin create 1-20 gain -3 > With Opus I noticed that the file size for 48kHz and 48 kbps > compared to 96kHz Vorbis at 31kbps is about...
