If by cassette recorder you mean the modern cheap SSD instead of in-built SD card then yeah, it's possible.

- rbanffy 6y agoNo. I meant (jokingly, of course) an actual cassette recorder. It can be attached to the GPIO's analog pins. Someone is probably still making them.
- unnouinceput 6y agoNone of the GPIO pins are analog, all of them are discrete. As for sampling audio from a cassette recorder you can use its USB - easier solutions already exists. Why complicate stuff through GPIO?
- rbanffy 6y agoSorry. I had the impression it had some form of PWM. In any case, we can always make it work with a square wave.
