Isolating the center only works assuming there aren't any theatrical effects directly behind the announcer and it's also assuming the announcer is in the left-right center of the show. It doesn't work at all on a mono sound track, and it has all the shortcomings of "Vocal Removal." Music a...

It's the second microphone and when the poster tries a different computer, that points to the Focusrite -- assuming the problem doesn't go away. If the problem does go away, then the USB on the laptop isn't up to the task. In that case, a single task, wall-powered hub may be the answer. Where did yo...

If you elaborate on exactly how you're trying to record your performances, we can advise you further.

Audacity has two tools you can use to set your recording volume. The recording meters and the blue waves. When you record in Audacity the red recording meters should bounce up to the right-hand third of their range. The blue waves should exhibit peaks in the 0.5 range like this. http://kozco.com/tec...

I am able to play the .wav file using the audacity but I don't know how to attach the marker so that I can get the onset of vocal reaction of the subjects. You can use the Overdubbing tools. Overdubbing is used in entertainment so you can, for example, listen to a rhythm track and then sing to it. ...

I'm generating increasingly exotic symptoms. If I amplify the ringing sounds in your clip, they also have, in addition to the tinkly bell sound, thumps and bumps very much like, (drum roll) a very unstable microphone amplifier. I would go to great length to plug the Focusrite into a different comput...

Most of it is oscillating at 3911Hz, highly audible, so the desperation method is a sharp suck-out filter (technical term) at that frequency.

Effect > Notch Filter: 3911Hz, Q=10

There's still problems down there, but they're much less audible.

So reading this carefully this time, you don't use headphones at all when you perform. It seems that everything is standing on the USB connection. Is that what you're using for the show sound, or are you using the analog outputs behind the Focusrite? The Focusrite gets its operating voltages (5 volt...

Oh, that's good. I would have guessed feedback, but if you're wearing headphones... I'd rather it just not exist in the first place. So would we. Nothing quite like the posting that starts: "Can you help me clean up..." No, probably not. Just to cover the bases, it happens after you restar...

Apple (upper left of the desktop) > System Preferences > Sound > Input. Is the iMic listed there? Select it. Does the little sound meter jump when you play music?
