Variable Rate Digital Delay

Posted in Synth DIY by ryan on the June 23rd, 2012

I have completed my first version of a voltage controlled sample rate digital delay. This module samples an ADC at rates ranging from 48KHz to 500KHz (1MHz was intended). It has a wide range that is controlled by a delay line length control in addition to the sample rate control. It can produce flanging effects and echoes. It is a work in progress, but I have written up a description of the design here.
