Play at speed button / slider don't work


I need to significantly slow down the playback (for research purposes). When trying to use the Play At Speed button I discovered that it doesn’t work at all, does not change the speed of the playback. Is this is a glitch or has it been disabled in v.3?

Is it possible to slow down the playback from 100% down to 50 and even 25% of normal speed?



found it!

Change tempo in Effects.

still, curious why the Play At Speed button is not working.

It works for me with Audacity 3.1.3.

Note that “Play At Speed” changes both the tempo and the pitch at the same time (as does the “Change Speed” effect). The Play At Speed button / slider does not change the actual track in any way, it just plays the track faster or slower. (Adjust the slider first, then click the button). Also, “Play At Speed” does not affect normal playback.

Works for me on W10 with 3.1.3 and 3.2.0 alpha master


for some reason your messages went to my gmail junk folder and I only saw them now.

I have W10 and current Audacity - still, it doesn’t work for me

never mind, I found the effect I wanted elsewhere.
