Just use the ABS(dela) to have an idea of speed.

You maybe have a chance if the source sound is totally fixed in term of dynamic (just an oscillator).
Your direction is almost good, by this way, you can calculate the speed of a sound, not really the acceleration. (the acceleration is the variation of the speed)

the delta value use the bloc size duration (use the module bloc-duration).
the delay is also suitable.

I need to calculate acceleration of a sound source moving in front of a microphone. I was thinking about measuring the increase (or decrease)of db level, using an enveloppe follower.
and then calculate the difference of level during a certain amount of time (which give me the acceleration/speed)? What's the best way to do this?
Can I use module Delta (but there is no time value)? Substract two values with a Delay? I've tried without correct result. Use arrays?
Thank you in advance
