This is what we need to add to our audio project:
We need to apply several filters to user recorded voice and put the result audio file on top of base song.
User recorded voice has to be copied 3 times. Each time it has to be moved 0,17 frames (1 second equals 24 frames), so 3 voices will be like a chorus from user voice.
One of the 3 voices has to apply a pitch filter of 12 semitones and it has to be put to 3 DB under other 2 voices.
Then, all 3 voices has to be applied a compression of -13 db.
You can see result in PRUEBA [url removed, login to view] file, with the user name recorded “Alberto”.
Here you have sample screenshots of these filters applied with another desktop software, and result wav:

Please let us know how many hours would it take. We need it asap, like this Friday.
