Extract audio from video

[vitalym]

I have a video with some music that I don't know the name of, so I just want to extract it out.

Does Audacity allow this? Or is there an easier way of doing it?

What format is the video in?

What you need to do is demux the audio stream, though the tool you need to use depends on the file container.

 

[vitalym]

The file is an .avi

In that case, give Avidemux a try.

VirtualDub can save the audio track of an AVI file as a WAV so you're then able to do whatever you want with it. Fairly simple stuff... load the AVI, choose File - Save WAV, give it a filename, done.

Yep +1 for VirtualDub

He did say extract, not convert to raw, which will always have a downside.

Uhmmm... WAV is not RAW, big difference, actually. But, if you load a file into VirtualDub and then you save out the audio portion only (as a WAV file), you have effectively - and semantically - extracted the audio portion of an audio/video file.

*Hmmmppphhh...*

No, WAV is raw audio.

No, WAV is raw audio.

"It is the main format used on Windows systems for raw and typically uncompressed audio."

That's what I thought...

Because WIkipedia is always right... right... yeah, riiiiiiiigggggggghhhhhhhhttttttt.

Try this one:

Note "wav" and "raw" are listed differently (WAV and RAW), and my comment above was specific to say WAV and RAW, not WAV (meaning the WAV format) and raw audio (which is what most people assume to be RAW and... well... it's not). I just made a sample recording with Sound Forge 9 and saved the content as WAV and RAW, two separate audio formats, the files are different sizes, different formats, and a binary comparison on them shows they are not the same...

Bleh.

Joe, you're still getting a bit confused. WAV is a container for raw audio, aka waveforms. When I say raw, I don't mean RAW as in format, I mean raw as in un-processed/untreated/unrefined/basic/simplest/etc.

Yah, I got that, long ago, went past it into "Ludicrous" territory... it's a tangent thing... I'm an audio production engineer so, the little details mean things to me as RAW and raw don't mean the same thing to most of us in day to day work.
