Been playing around with GoPro making some short biking based films, to date basically ignoring audio and splatting music over the top. Would like to introduce spinning hubs sounds and crunching gravel, puddle splashes etc, sound recording is a bit pants though. What’s anyone doing. Oh and cheap. Not buying 100quid mics to strap to bike/trees etc.

If you’ve got an old phone you could try taping/ziptie it to your frame and then sync up the audio.

You can get a plug into one of the plugs on the side of go pro cameras if you need an external audio. Question is what sort of sound do you want?

Fur over the mic to cut wind noise. It doesn’t have to be an expensive fuzzy windjammer, plenty of people doing video DIY them out of some furry fabric from a market stall. Just make sure it has a good seal around the mic and it’ll cut out loads of wind noise, and with that gone you might be surprised at what it can record.

Just don’t expect miracles. The crystal clear bike noise you hear in fancier videos will be at least from a shotgun mic, if not a mic+recorder/tx mounted on the bike or rider.

AudioTechnica do a decent, cheap lapel mic for about £20, though it eats watch batteries and has an absurdly long lead. While shooting stuff and riding, I’ve been surprised at how well that+windjammer can pick up not just my voice, but bike noise too. Of course, then you need the £20 usb mic adapter (cheap ones don’t work), and a GoPro case with a hole for it, etc.

Try the touchscreen backdoor if using a case. Its still waterproof but lets more sound through.
