Record Sound...

Record Sound lets you record a sound into Mathematica. (Windows and Macintosh only.)

With a sound recording peripheral and microphone connected to your computer and the proper drivers installed, you can record sounds directly into Mathematica. To record a sound, first place a cell insertion point (horizontal I-bar) in your notebook, then choose Record Sound. A dialog box appears with buttons to control your recording. Once you have recorded a sound, click Save to paste the sound in your notebook. Mathematica can play recorded sounds just like sounds natively generated in Mathematica.

You can use the Convert to InputForm command to convert recorded sounds into a list of numbers (samples) in the form of a Mathematica list.
