I have recorded several guitar takes as close to the beat as I possibly can, but obviously I want them to be absolutely spot on. Absolutely perfect timing is essential because I want to use some rhythmic delay. My friend is in a band and said that he has seen someone with pro tools just click one button and the entire guitar part shifted slightly so it was perfectly in beat. I don't mind if it doesn't feel natural, timing right now is most important to me.
He may have been using a plugin or something, but either way, how do you do this? I have googled and searched all over the place but the wrong articles keep coming up and I just can't find information on it.
The BPM is 95, and here are the 5 loops I've recorded. I've left a little bit at the end of each one so it doesn't cut off straight away. These are the direct input recordings, no effects at all.
Not sure what the tool is called in Pro Tools but Sonar calls it Audio Snap. It works best with transient type music like drum parts. Sustained guitar has not much in the way of peaks so is a crap shoot as to what will happen. But a choppy guitar part can work. It can add artifacts and the best way to avoid this is only apply the rendering to parts that seem to need it.
PT elastic audio is nice, for rhythmic parts with well defined attacks Beat detective (or tab to transient as an alternative) would work fine also and you won't stretch the file so audio would stay intact. Just separate the main notes and use "quantize to grid" or do it manually, then fade everything.
Here's the strum quantized to 16th at 95 without time stretch.
PS: strictly quantizing sometimes kills the part feel IMO.
