All clips in my project have been warped to bring them into time with each other. I found the hip-hop and rnb ones the most difficult due to the fact they are more complex and have sounds and instruments launching at different times compared to the 4 by 4 beats I use later in the set.
- First I chose an 8 bar loop I wanted to use for my intro, I cropped it, leaving a little audio either side in-case the start point needed to be changed to sync with the metronome.
- I selected warp in the clip view and set marker no.1 to the start of the first beat and marker no.9 to the end of the 8th beat ends as it is a 8 bar loop.
- I started the metronome and finely edited the start and end points and cropped it again to the piece I’ll be working with.
- I then went into the other markers through the loop. By double-clicking it selects them and makes them movable. I adjusted them to the beat until all hits were in time.
- I also changed the transient from beat to complex which made it sound smoother and clearer.
- Notice the hits aren’t on the markers for this as the style of singing I have is slightly off beat.
I now had my first warped clip, only another 50 or so to go!!
Editing a full track
I had a 3 minute acapella I wanted to use in my set that needed warping into time. When I loaded it, Ableton auto- warped it, changing it to the approx. BPM to match the instrumental it would be playing alongside. Otherwise I would of set my end marker to 97 as I know the piece is 96 bars as it is exported from cubase and I could see this, or I would of had to count the bars. Although it was near enough the right speed the beat was way off so I deleted every warp marker within the piece except for the start and end markers. I found this easier visually to watch the time line going over the clear audio at normal speed, to see where it needed adjusting.
Moving the marker to the right makes the piece go faster, you can see the logic of this as when you move it to the right more audio is fitted in that bar and so will have to speed up to fit it all in, and moving it left will leave less audio in there meaning it has to stretch out and slow down to fill the bar and as I just mentioned, the time-line will slow or speed to roll in time so a bar made smaller will make the line slow to take a full bar to reach to the end. Another visual aid is the beginning of each beat or word is seen in the waveforms and you can zoom in and place the markers appropriately.
A tip I found when warping a long piece of music is after setting your end marker, take the bar marker near the end of a verse/chorus and set that to end right, now I know this is correct I can concentrate on smaller beat markers throughout the verse/chorus knowing it will end right so shouldn’t need too much adjusting. It also breaks up the work a bit and ensures you don’t adjust all of the markers till the end which can take the continuing audio all out of sync as some of the auto warped stuff will be almost correct in the first place.
So that is what I did for the full track, set some main bar markers then went through the beats playing alongside the metronome and bringing the warp markers into time looking at the audio wave thinking what beat that word went on and placing it there. Some parts had to be sped up, some slowed down, and some needed less adjusting as you can see in the picture. As the acapella was recorded for a different style of music altogether it doesn’t stay in time once set. When this happens the only way to fix it is to go right into the beat markers, even adjusting one word to make it fit. Moving the markers from left to right means you can lengthen or shorten any silence, word or beat of music and you can always make it fit if you have the patience, but warping an old blues style vocal over a 4 by 4 beat is gonna be trickier than a dance vocal would due to the similarities in sequencing.

A full length acappella warped into time. The loop marks show where I want it to repeat a loop within the track before jumping to the next bars.
Every clip in my project is warped but this isn’t always necessary, audio such as sound fx, samples with no rhythmic structure or spoken word may not need to be warped as you may not want these to fit perfect to a beat but two beats you want to fit together will.
To further ensure the audio sounds correct there are a no. of settings for warping.
- Your auto-warped sample could be warped to the beat perfect but be doubled or halved in tempo in which case you can select the *2 or :2 which will tell ableton it’s guessed the tempo wrong by half. :2 will tell it to double up the tempo and *2 will half it.
- There are also different warp modes which time stretch the audio differently to be suitable for the type of audio:
- Beats – For simple beats such as drum beats without too many other instruments
- Tones – Works well with vocals or mono sounds like a bassline which has a smaller range in pitch. It includes a grain size control which works with the signal it receives of the audio, usually the less erratic the pitch, the smaller the grain size should be selected
- Texture - This works well with a bigger range of pitches such as polyphonic, orchestras and atmospheric pads.The grain size on this will again adjust the size used but this will be irrespective of the pitch contours and will increase the same for any textured warped sample.
- Re-pitch – In this mode the sample is transposed to speed up or slow down rather than time-stretched or compressed. Its a bit like when you assign a sample to a keyboard and hit the keys further up, as its transposed up it speeds and transposed down will slow it down. Another way to look at it is the DJ stretching method of altering the pitch to sync a record.This will probably work better with music or a beat rather than say a rap vocal if you wanted a ‘clean warping’ but you could have fun
- Complex - This mode is used to cover all aspects of the others, useful for full tracks where you will have beats, tones and textures but is very CPU intensive, using ten times the resources of other warp modes
