Audacity Forum

What effects would I use to make a voice over sound like it's coming from inside helmet?

I use audacity to change the bitrate of a clip to 16 and the project rate to 22050, but when I export it as a .wav and open it again in audacity, it's reset back to 32-bit and 44100Hz. This is really annoying because It has to have those settings for another program. Does anyone know how to fix this...
