Using Raspberry Pi + Wolfson Audio Card to create an audio delay solution?

Question

Hello!

I'm curious if anyone can provide direction for using The Raspberry Pi with the Wolfson Audio Card as an audio delay unit.

I would like to take line level audio in, specify a delay, and send line level audio out.

Thanks!

HI,

See my post here:

Using Pure Data to make the delay (G01.delay.pd (replacing the tabplay~ by [adc~])).

You don't need the preamp, since your signal is line in / line out.

HI,

This solution can be sample accurate AFAIK. There's a PD patch to calculate the round-trip latency of you setup:

PD is rock solide, it has been used in live setting and installations (running for many many months).<

Let me know if you are facing problems with it.

Cheers
