I put a phone on speakerphone and put it by my computer with audacity recording
I wondered why more people don’t do that. Given you’re paying attention, that’s far less complicated than trying to throw wires back and forth between the phone and computer.
You can improve the quality by padding the desk and possibly creating a kitchen table studio instead of trying to record in an open room.
That illustration is for live reading, but you can slide the phone and laptop in there and eliminate the room echoes. If you juggle it just right, you can hold an interview like that.
There is no glue. You can knock it apart and slide the whole thing under your bed.
