@@NeoPlaysViolin A little of everything, but especially the audio quality. It sounds far too "tinny" (not sure if that's the right word in English. I mean like thin metal.). I guess it's because of the mic, not because of your playing :-) Especially with good headphones. Some videos sound almost like an electric violin because of that :-/
Gotcha, thanks for the specifics and I think you are right; most people don't notice (or don't comment). I really should invest in better equipment (I record on everything on my phone) but it's just a hobby for now... If I ever get to the point of monetization I would definitely need to step up the game. :)
