Mum found a bunch of tapes of us making radio shows when we were kids. I’m digitising them now using this radio, which is the only tape player available to me. Not pictured is the Nuc running Linux, recording the audio (forgot how painful dealing with Linux audio on the command line is).
This is cool, but I see a couple of issues you may want to consider.
As a guitarist, I’m pretty familiar with these types of audio interfaces. The audio out on the headphone jack is likely stereo/TRS. The line in on the guitar jack is single channel mono. You can solve this by getting a split cable and plugging into both on the audio interface.
You’ll also want to ensure the audio interface jacks are set to line level. If it’s set to Hi-Z, there will be an impedance mismatch.
Good luck!
@bryan Ah, thanks for that. Yeah, I was wondering if I could get away with just mono, since the recordings were made on radios with a single mike. But yeah the cable is stereo (and probably the line out as well) so that does mean I'm only picking up the left channel. It might be worth getting a splitter, if anything to avoid loosing the right channel completely.
