i am being left a voicemail that has the persons voice altered and the call is a private number. i was wondering if i can reverse the effects of this. possibly by using matlab and fourier transform(s). I contacted my phone provider and they said that they cannot give me the number of the person unless i have a subpoena, which i dont feel like going into.
the voice once modulated is very difficult to change. we have to know the code which he used to modulate the signal.and mostly it will be an 8 bit message. this will create more problems in identifying the person. So, its near to a NO.
