I designed with ADAU1442
want to make a phase shift between left and right channel
sample is 48k ,please check the block and give me suggestions
If what you desire is a 90 degree lag in the 0.1 Hz tone for Channel 1, you can use a Quadrature VCO. This block has the two outputs you need built-in. It just needs a DC input to set its frequency, which is:
Vin = 2 * frequency /fs = 2 x 0.1 / 48000 = 4.16............. x 10^(-6) = .004167 x 0.001
I added the gain block just to make the DC input entry easier.
I couldn't test this idea because the Quadrature VCO is not available for my hardware (the humble ADAU1701). Hope it works for you.
Did my post above work for you, or do you need a different solution?
