How to match a vocal to a beat's tempo

The easiest fix is usually no fix at all: half time and double time already line up. Check those before you stretch anything.

Try half and double first

A vocal at 130 BPM lines up with a beat at 65 or 260 with no stretching. Trap is often written this way, so the numbers can look far apart and still fit.

Work out the stretch

Take the difference between the two tempos and divide it by the vocal's tempo. Going from 130 to 136 is about 4.6 percent.

How far it will go

A few percent is usually hard to hear. The further you go, the more the voice starts to smear, so past that it is worth changing the beat's tempo instead.
