How to change voice (disguise) without formant, pitch analysis,etc,
using only simple common DSP method as Hilbert transform and forth.
Unfortunetly I have some mips only.
Maybe this problem hasn't decision in these circumstances ?

There is some nice software for the Microchip dsPICDEM 1.1 board that includes pitch changing: http://www.moetronix.com/dspic/ It makes my voice unrecognizable. It will run on a minimal two-chip system - dsPIC30F6014 and an SI3000 codec. Leon -- Leon Heller, G1HSM http://www.geocities.com/leon_heller
