Please comment if you download, i am interested to see what it's being used for. I am not looking to be credited at all it's just pure interest. I do this for fun. I did this with my mouth and pitched it down 3 semitones. No other effects were used.
After recording 2 soundtracks of a voice (high-pitched and low-pitched), i've selected the interesting part, and applied to it a cross fade out. Then i've mixed the soundtracks together.
