but maybe aneurisms as well.<br>
<br>
Interestingly enough, audio at varied play rates has the potential to retain tonality. Since the audio is encoded with something<br>
like a Fourier transform, the data is "spectral" rather than "wave." The samples may be presented tonally-accurate even if their<br>
duration is not 1:1.<br>
<br>
Nonetheless, you're going to be very unpopular if the word "required" starts showing up.<br>
<br>
Best!<br>

I agree that on the long term we would want to provide this, but I think<br>
that is something we should offer as a separate feature (e.g. a flag that<br>
decides whether reverse-playback audio is muted or not, defaulting to true<br>
for compatibility with today).<br>
<br>
If there's some way of turning this feature "on" (when it is available)... that would be sufficient for scrubbing AFAICT.<br>
