Any tool to easily record audio from movies?

Question

Is there any tool that I can use to record audio to mp3 when I watch movies on my computer easily .

I know some software but I need some software which work in the background so I can simply use some hot key to trigger recording and stop and export the file to disk and auto-naming the file.

So I can record multiply audio clips along watching the movie with minimum effort.

Answer 1

I have no idea how do you actually execute this if you're NOT using Windows:

Step 1.) Enable Stereo Mix. Use this guide

Step 2.) Get Audacity

Step 3.) You're gonna have to setup up stereo mix.

Step.4 ) Don't forget to arm the track by clicking on the record button on the specific track.

Step.5 ) Hit the big record button on the top to record the sound.

That's the cheapest solution for windows. The setup up stereo mix link has a few other instructions for Mac and Linux users.
