Thanks for all the feedback folks. I'll change the music next time but I dunno if it'll be better or worse.
There's little chance of less swearing but I'll see what I can do.
Bike noise while riding is a tough one at the moment. All I pick up currently is wind noise. If anyone can recommend a cheapish mic that works with a gopro 7 then get in touch.
cheers
Mike
Apparently the trick is to use two devices. e.g. audio recorder is a phone placed under the seat.
Example I saw had phone wrapped in cloth placed in seat cowl; cloth wrapping for phone or mic protection? I dunno.
Then merge video and sound recordings.
