I tried connecting the two headphone jacks to each other but the Mac is not recognizing this as an input source. I also have a cord to connect the headphone jack on the cassette player to a USB but the Mac isn't recognizing that either.
What is the proper way to go about this? I know nothing about cords and inputs/outputs. I want to somehow feed the audio from the cassette to the Mac to eventually be able to digitize the audio on the cassette tapes.
