Karaoke

So I'm trying to make a Karaoke VI which inputs a file from the computer, plays it while the microphone records, and ends when the sound file ends. However, I don't know how to make an internal vocal remover, and I don't know how to break a while loop inside an Event Structure.

Any help is appreciated:

I didn't look at your vi but I ran across this example when I was looking for something else.

Hope it helps.

You shouldn't have long running loops inside of event cases. Especially since you have your event case to set to lock the front panel until the event completes, the stop button can never stop the while loop.

So I need only to disable the defer user input thing?

Also, what do you recommend me to do instead?

Now I'm trying to save the audio as a result of adding the background music and the vocal. However, the output comes out garbled. How do I solve this?
