i am trying to figure out how to read audio from a delay line in reverse. clearly, it can't be done as simply as that line suggests, because the delay isn't a static array, but is merely playing the audio input through at a later time. it would need to play into an array instantly when the reverse feature is switched on and then read the array backwards without any significant latency. i can sort of muddle through a bad solution based on the samplers included in the tutorials, but those are absurdly resource intensive and cause a lot of audio dropouts for me.

if anybody has any ideas on how to do this more simply, i'd appreciate the help. it may be that i should just buy a delay pedal, but they are so expensive.

[vd~] will be your friend for this one. first, you'll have to specify how long the segment you want to play back in reverse is, for you oviously can't reverse something continuously. then you need a vd~ initially at twice the delay time that the length of your reverse segment. now we'll take a line~ to fade the length of the vd~ from (2 x segment length) to 0, within the length of a segment. you can loop this behaviour to get a more or less continuing effect, but beware that the reverse-delay rhythm has to hit your musical rhythm in some way, for otherwise it would sound queer

Okay, that's really confusing. I've trying to get this to work for like.... eons. I figured out all sorts of cool stuff along the way, but is just don't work backwards. Can someone PLEASE post an example? I am about to explode....

Nestor, i was surprised by this one myself, but then i threw something very simple together to try it out, and indeed it works...

Have fun,

Ummm yeah. SO it does, in fact work. I still haven't figured out why I couldn't get it.

Two Delays for you to try.

Dizlay -- Randomized; Bleepy, and also Bloppy.

Bungee -- Backwards [phasor~] driven delay. Two modes, and no clicking.

Both delays need Arguments specifying delay time in ms.

thanks for these patches

Tried bungee on acoustic guitar and it sounds sweet.
