I got an audio recording (voice only) from a friend which timing is between 70 and 90 bpm. To get this "quantized" I recorded a "click track" by simply playing a MIDI track using a VSTs sidestick. Then I generated a tempo track with the tempo detection tool, source was the sidestick. So far so good. Now I can quantize the guitar I programmed for the song. But the whole song is still varying its tempo because of the tempo track. This is good, because I can sync MIDI tempo with audio tempo. Now i would like to have the song in a straight tempo, let's say 80 bpm. How can I achieve this? I guess I have to "quantize" the audio track I got somehow but I do not know how. Any help is appreciated! Thanx in advance!
