Re: Really fast (50x) playback speed possible?

Yep. Got all that. Remember we're talking about 10-50x zoom levels and 24 hour recordings. It takes a very long time, like a few hours, to review the file visually at a useful zoom level, which is about 90 seconds wide. By ear at 50x, a first pass can be done in a matter of minutes. Should I think a...

For example, I'd like to listen to the file at 10, 20, 30, 40, and 50 times normal, and switch between them. Scan through at high speed, then replay at lo...

Really fast (50x) playback speed possible?

Hi, I'm using Audacity for listening to really long (24 hour) EEG brain activity files. I'd like to listen to them at very fast playback speeds, like 50x, without using "resample" and "change speed". The "play-at-speed" and "playback speed" on the transcriptio...
