I just got a Blue Yeti microphone (professional USB microphone) as a gift and have being playing around with it and with Audacity and would just love to provide voice acting for the mods pro bono. I speak fluent (mostly American) English, though I am originally Italian, so that prosody and vowel pronunciation sound occasionally different, not impeding comprehension, but giving the voice its own note.
If you want to point me to any tutorials to help with sound or anything else relatively simple I could be working with, please do.
And if you want me to voice your mod, PM me.
