Hello,
I am on a PC operating Windows 7 Home Premium, and using Audacity 2.0.5. I am wondering if it is possible to employ live audio processing using Audacity, specifically Delay. That is, can I preset Audacity to apply a certain Delay to whatever audio I record instead of having to record the audio first, and then apply the Delay effect to it? I am looking to creating a specific delay effect of 566 milliseconds, which would be 0.00566 seconds, correct?
I have tried selecting Delay when no Audio Track has been created and met with a message that I must select audio first. I have also generated an Audio Track and then tried the same thing, resulting with the same message. I feel like this should possible but I don’t know how to make it happen. Please help me!
The delays mentioned in Audacity have to do with making an overdubbing session match. When you sing to an existing backing track, your voice matches when you play back the composite.
Audacity can’t do effects in real time.
I had to do this once at work and I ended up using a much higher end audio program.

Nope!
566mS is 0.556 seconds (slightly more than 1/2 second). You’ll hear that as an echo if it’s combined with the original (non-delayed) sound.
0.00566 seconds is 5.66mS. You wouldn’t hear that as an echo. If you combine the delayed signal with the original you’ll get a comb filtering (a “phasing” effect).
One millisecond is 1/1000th of a second (not one millionth).
Are you trying to make an echo, or just to timeshift the recording? If timeshift, you can do it by generating a track first of all, ensure Transport > Overdub is on, then set a latency correction of your desired positive amount in Recording Preferences. Those are the overdubbing corrections Koz refers to.
