I am using Ableton live 8. I just recorded three tracks of live audio (vocals and guitar) and did not pay attention to the BPM of the song. Now I would like to tap the correct BPM without stretching the wav files or modifying them in any way.


Turn off warping for those clips that you recorded into, now they'll play at their original rate regardless of the project's tempo. You can now tap the tempo in to figure out what it is, and then go into those clips and set that as their base tempo. At this point, you can re-enable warping and the tracks should be playing at the same rate as before, since their base tempo matches the project's tempo.

However, if you're using the Complex or Complex Pro warping algorithms, keep in mind that the sound will still be slightly different than the original recording, even with those tempos matched. The other warping modes do not exhibit this behavior: if the tempos match, it's sample-accurate.

This is described in an appendix in the Ableton Live manual, which I don't have in front of me at the moment.


Click on the clip in your Arrangement View, and at the bottom right you'll see the name of the clip in a small box. To the left of that box is a tiny picture of the clip's waveform, in a box the same height (this is the Clip Overview). Click on the clip overview, and options for the clip will be in the area just above it. Under the Sample options there is a button named Warp. Make sure it is not active, and you're all set.enter image description here


If master is 120 it seems to automatically adjust to song after it finishes loading in arrangement

To purely determine the bpm of your track:

  1. Put the song in session view, otherwise the song will skip around
  2. Turn off warping and Play from a chosen loop start point
  3. Tap tempo to get a rough estimate of song's average tempo

Usually if you just align the song with the clip editor's grid, you can play back with any master tempo, but it's good to have a similar master and clip tempo)

  1. put the song in arrangement view, then double click to edit clip
  2. right click set 1:1 here on the first kick drum
  3. drag start point back to the start (sometimes this is all u have to do)
  4. line up every 4 bars with a grid line by using yellow warp markers. if you have any yellow warp markers and drag a grey transient marker, it will stretch the track relative to the yellow warp markers (which are "locked in stone")
  5. in arrangement, make sure that first kick drum falls on a grid line
  6. before export, drag clip to the start of arrangement
