How to adjust volume in audio files?

[Tunch Khan]

Is anyone here familiar with modding the audio files? I made some wave files for unit slect and order voices for my mod and it seems to work fine in the game, except the voice is so low and I believe I hear slight echoing which doesn't exist in the original wave file I created. Does anyone know how to fix this, or any suggestions?

I use GoldWave, they have a "maximize" volume effect and other effects that should allow you to make similarly volumed effects. If you open both a similar volumed sound from the game and your effect at the same time you should be able to adjust yours to match.
