Having extreme difficulty getting an audio signal back to the time domain using the ifft function. I think it is related to the imaginary (phase) information when reconstructing the signal...any help would be appreciated

How on earth do you expect to get help with the amount of information you have given us?
With my crystal ball in for service at present, the only help I can suggest is to type
help ifft
and read the information very carefully.

You are very lucky to be able to have it serviced. I dropped mine and it broke into more pieces than I could ever hope to glue together.

Oh sigh,

I'm not an engineer so the snide comment is was wasted. Come out of your parent's basement sometime and get some fresh air.

You haven't given the group nearly enough information to be able to provide
you any useful help. Show a (small) sample of code that the readers can
execute that behaves differently from what you expect and explain what you
expected it to do and why. With that in hand, the readers may be able to
explain the problem (whether it be in MATLAB, your code, your expectation,
or something else.)

Oh yeah.... that one will certainly earn you a lot of free help.
