I got this idea yesterday, and made it in a span of two days. Arm your track before hitting record, and to pause the record press the pause button. to stop press the record button again. Hit settings to adjust the resolution, zoom and whatnot. MAKE SURE YOU PRESS ALLOW MICROPHONE AND ENSURE IT'S TURNED ON.
All code by me. When exporting just right click the text string you're prompted with. To import, copy the text string and paste it into the thing.
