Dear Team
Good day!
Our customer want to use our miniDSP in their application ,like voice input through the microphone, male voice can be converted to female voice and output from line out .
As my understanding , the AD collect the signal and do the FFT operation , change the signal to the frequency domain .then add the zero at the low end of the data. so the frequency will be raised .then do the FFT inverse transform to the timing domain .then you will get the voice which is raised tone . you can sample from the time domain .
Does my understanding correct ?
I did not find any useful reference design or information which describe our MiniDSP can support this application . Could you help me to confirm it ?
Is there any recommend devices? or software sample ?
BR,
Leon.liu
