(It’s a sample in the FMOD EX SDK ,named ‘DSP custom’

I want to change a person’s voice (a man to woman,or woman to man)
so what shall i do?

I don’t know exactly what effect you are trying to achieve, but I think you could use the built-in dsp FMOD_DSP_TYPE_PITCHSHIFT to change the pitch of the person’s voice. Increase the pitch to get more like a woman’s voice.

Are you looking for a algo for pitchshifting and want to recode it yourself? It’s not that easy… try this page [url:219ef1e2]http://www.dspdimension.com/admin/pitch-shifting-using-the-ft/[/url:219ef1e2]. I think FMOD’s dsp is based on this algo. Or are you just unsure how to program a dsp in general?
