Mono mic: how to convert to stereo?

[Thumper Strauss]

I have lots of home movie (MiniDV) where I used a handheld mic. The mic is mono, so the sound only comes out of one speaker.

What is the best way to mix the sound during the editing process so that I get (fake) stereo sound? So I need to extract the sound from the AVI file, play with the WAV in an audio program, and then stick it back to the AVI file? Again, what software can I do this with.

Gold Wave. Load your video into it. Copy one channel, mix it to the empty channel, save as a stereo wave file.

sound forge has a mono to stereo setting with invert phase psuedo - stereo setting or just mono to stereo

just throw your DV avi into that and re-render audio (select avi/DV) (it will render to another dv avi without touching your video)

You should be able to do this right in your video editing program (unless it's too crippled). I use Vegas 4 to edit and burn caps of old home videos that have mono sound. When I render the video I specify stereo for the audio and it just puts the mono on each track.

Or, for a quicker solution when recording in the future, buy one of these for $1.99 (should be available from Radio Shack) or use this website: http://www.audiogear.com/AudioAdaptersMini.html
Then you'll have the same audio going to both channels when you record, and you don't have to futz around with any programs later.

Audacity will convert mono to stereo and it's free,just import WAV twice and select Make Stereo Track.I recommend v.1.0.0,later versions are buggy.
