I am writing microcontroller code for ISD17XX (really ISD17240) series chip corders.
I am applying PC sound card output to ANAIn input of ISD. When I use FT to pass input signal to the output, sound quality is very good. When I record that sound and play it from the chip, the quality of recorded sound is awful! Any suggestion? I have changed my chip, but nothing changed. (Circuit is on bread board).
Thanks
