Replying to [comment:9 cehoyos]:
> IS this still reproducible with current FFmpeg git head?
No, not on sine440Hz_24bit.flac and sine_tester.flac (See #2686 Sine waves
for a warbling test. 50 440 1000 3000 7000 10000 20000Hz. 24bit 48kHz PCM.
), {{{-q:a 1}}}, {{{-q:a 2}}}, {{{-b:a 128k}}} and {{{-b:a 320k}}}, on
default on N-75950-ge652f69. The warble remains in perceptually acceptable
range.
