Echo Hall adau 1701

Hello,

adau1701 isn't really suited for echo/delay effects unless you are happy with very short delay times...You can get a maximum of 42ms at 48khz, actually less because each other block in your project will take up some memory too.

There's a schematic from the great KJBob which can double the delay time by using a Synchronous Multiplexer:

If you need more delay time adau14xx can do that.

maybe you have a recommendation for me for a dsb board

Hello ,

ADAU1452Z Rev.B would be a good choice.

You can go with either ADAU145x or ADAU146x series Eval boards. The ADAU146x series have higher memory unit.
