You're kinda skimpy on details here: i.e. format of the video, intended format of the finished product, etc. Also, there are possible copyright issues involved.

But suppose the audio was in an AVI. I'd load the AVI into VirtualDubMPEG2 (or any other version, but as the name suggests, it's not limited to AVIs). File -> Open Video File. Audio -> Full Processing Mode. File -> Save WAV. You now have just the audio, uncompressed. Open in an audio editor like GoldWave to clip out the desired part. Match video length exactly by using the "warp" function, if necessary. Mux or re-encode audio and video together to whatever the final format is to be.

Or some other variation, but the idea's the same.
