Audio restoration

I received a call about restoring the voices recorded by an in-car video system. Unfortunately, the siren obscured the voices. Audio restoration always involves trade-offs. In this example, removing the siren can remove part of the voice that occurs during the siren. So you may have to reconcile solving this problem with the infamous law of unintended consequences. Thankfully, Adobe's Audition allows for some very strategic and targeted edits. When done in the Spectral View, you can be very precise in removing unwanted noise - but you'll still lose a bit of information.
