Varispeed is a feature I didn’t realize existed until recently, but had always wished for. It lets you speed up the audio playback so you can basically listen through your podcast at 2x while editing.
Once the toolbar item is enabled, just use ⌃F (Control-F) to toggle it on and off. (I think that’s the default, but I might have edited that one. We’ll get to that below.)
Once it’s up, ensure that the type is set to Speed Only (click the top line for a menu), then double click on the percentage to edit it anywhere between -50% and 100% (100% being double normal playback speed). While playing back you can just hit the shortcut to speed up and then toggle it back off to return to normal speed. Scrubbing!
Some great stuff here.
