I don't know much about this, but I think John used an application called "Sound Studio" to record Fister's voice from a Dictaphone back in 2003. I found this, but it's old and there may be something newer and smarter.

Installation

If you have a version of Sound Studio that came as part of a hardware bundle, please see the "About Sound Studio" file that came with the bundle for installation instructions.

If you have not entered a license code for "Sound Studio 2" before, the app will run as a trial version for 14 non-consecutive days, or until you enter a license code. If the 14 days are used up, the app will disable the ability to save files. At any time, you may enter your license code to unlock the app and re-enable the ability to save.
