Without a drum track to drop markers on, warping an acapella can be especially challenging. This quick little tip makes it easy.
For this method to work, you’ll need not only an isolated acapella track but also an accompanying drum or full length track of exactly the same length. If you’ve extracted all the tracks from a DTS recording or happen to have a set of stems from a multitrack session, you’re good to go.
Follow these 3 simple steps to quickly warp an acapella:
- Drop the song’s drum track into a clip. Place warp markers or auto-warp the clip to your satisfaction.
- Copy that same beatmapped clip into another session track. Highlight that copied clip so you can view the waveform at the bottom of the screen.
- Drag the acapella audio file on to the waveform of the copied clip. Notice that the drum track waveform is replaced with the acapella but the original warp markers stay in place. This is what we want.
Here’s a movie walkthrough of the aforementioned process using the stems for “The Bomb” by New Young Pony Club.
So what happened? Using this technique, I was able to quickly place warp markers on a drum track and then apply those same markers to my acapella track. In comparison, if I were to warp the acapella without a guide track, my attempt would be prone to timing errors due to the guesswork and estimation involved.
