Me and a friend did some co-commentary while he was at my house earlier this week, and I’m editing the footage and the audio. The problem is, the mic was closer to me than him, and my voice is much louder than his. I removed the background computer noise with the noise removal option, and I like the way you can select a certain audio pattern to remove. Is there a way to use a sample audio pattern like this and amplify the volume of just his voice? Or is this out of the capabilities of the program? I’m pretty new at Audacity so simple instructions are probably best.
Well, not automatically, no. You can use the Envelope Tool (two white arrows and bent blue line) to place volume control “rubber bands” in the show. You can pull the rubber bands up and down – manually – word by word to correct the volumes.
Here’s an example of a cross-fade. The little dots are click control points.
And a note: Noise Removal always damages everything a bit and it’s a juggling act to get it to work right. Far better to record in a quiet room.
The envelope tool would be one of the best approaches, http://manual.audacityteam.org/o/man/envelope_tool.html
but that could be very tedious if it is more than a very short recording.
An alternative method that you could try is to apply an “Automatic Gain Control” effect to the recording (try it on a short section first to get the settings right (Ctrl+Z to Undo). The plug-in and instructions are here: https://forum.audacityteam.org/t/agc-automatic-gain-control/26706/1
