Audio editing with warp feature

Post by Laura R » Sun Jul 21, 2024 12:43 am

How do I use audio warping to move just a select few off- tempo guitar strums? Most of the videos I’ve watched about warping focus on warping a sample to fit a beat, etc. I’m just trying to clean up a messy guitar part for a guitar and vocal song demo at the moment. Also does anyone have an opinion about what % of quantization sounds steady but natural if you decide to warp the whole guitar track to match the grid? All advice about this topic is welcome. Thanks for reading.

This can be hit and miss tricky. It is easiest to fix mistakes when the entire clip is mostly on-grid. For starters, for different phrases of 2, or 4 or maybe 8 bars, it is nice if each phrase has a marker associated with it that makes sense. For example 1.1.1 might have a note or chord that hits on the downbeat. And it plays along and 4 bars down, when the next part begins, the note in the guitar recording should align with 5.1.1. But this is assuming there are even actual notes on the downbeat.

By doing this rough way of counting and aligning, your audio clip should mostly play along if a drum beat was also playing along to it. The benefit is that you can then go inbetween these points and find sections where the timing deviates most and add a marker to the worst offender and slide it to where it belongs on the grid. This works great when there is already a marker before and after, because it means only that specific section will be affected.

If you have a section where everything is in the right place except for a very specific note, then you want to add markers to the ‘good’ areas before and after the offending note, and then put a marker on that note to push it over.

When starting out though, I usually remove all markers first. And then add ‘1.1.1’ as a marker in a good spot where it makes sense as a reference.

Finally: the nice thing is that the clip would now play mostly nicely along to a perfectly timed best. The bad thing might be if the take was recorded without a metronome or steady reference, this could take some of the life or soul out of the clip or the song as a whole. There are ways to work with that too, but I don’t know if the results are fully satisfying.
