Tragic things can happen when mixing audio or video clips from multiple sources. Sound levels (read: volume) can fluctuate erratically, causing the resulting splice of tracks to be inaudible. To stop your viewers from having to play games with their volume nobs while watching your videos we will cover some techniques here to remedy the problem.
Tools you will need:
- Software to process audio tracks (I use Audacity.)
- And something to mux/demux Video (I use VirtualDub.)
Audacity - http://audacity.sourceforge.net/download/
VirtualDub - http://virtualdub.sourceforge.net/
Some points I would like to make:
- If you can run a filter called "Normalize" on all the tracks you are mixing. This will make it so that everything has the same maximum volume. If you do this you avoid having to do...
- Dynamic Range Compression should not be confused with plain Compression. Compression refers to making a file smaller. (We will be doing Dynamic Range Compression)
If you can find other software to do these things then good for you! (There is more than one way to skin a moose.)
