Hello guys,
I need help about how to process an audio using Matlab. I need to get the center frequency of a song that I used. After that I need to extract the singer from the song, double the center frequency and add it back to the extracted song. I really need help...ASAP.
Thank you very much! ~Daniel

Samuel, thank you for your response. Is there any step by step tutorial that you might know? The thing is I'm kinda lost... If I have a song, should the center frequency be at a small interval of frequencies(bandwidth) or it should be b/n the whole bandwidth??
Thank you again!
