If you want to stop and hear the recording press the Up Arrow and Space. (Now for the notes,)... The lower Quality is the best Quality. If you have problems with the loudness1 list saying -1. Then you need to give scratch access to your microphone. If the list reaches 200000 too fast. Then change the Quality var up. If it's already at 0.1 then just make things short. Enjoy it!
