chrisjunlee Posted September 16, 2019 Share Posted September 16, 2019 In preparation for my Nikola 100V vs 16X video, I would like to record clear audio while really pushing them. I know the current EUC vloggers use lavalier mics clipped to their shirts - and that seems to work fine at lower speeds. I picked up a Tascam DR-10L, and gave it a go. And thus far, anything over 20 mph is unusable. Positions I've tried: clipping on collar: excellent SNR (signal to noise ratio), but prone to turbulence clipping inside breast pocket: poor SNR, better resistance to turbulence (due to more laminar floor), but still unusable There are expensive deadcat covers, but those will be ineffective at speed. My intuition is, we need highest SNR + completely dead airspace within a laminar flow bubble. And the only way to do that is either: throat contact mic full face helmet with chin seal + mic near side of mouth At this point, I'm leaning towards the latter. Which would mean picking up a Shoei full face and modding it for recording. I've looked into Sena's offering, but I'm not happy with their sound quality; they apply an aggressive bandpass, and it sounds too artificial. That also means their boom mic would not need to be good quality. For posterity, here's IMHO, the BOM for the ultimate no-compromise audio setup: shoei full face - $500 chin curtain - $10 mic: sanken cos-11dĀ -Ā $400 bubblebee: $50 sennheiser EW system -Ā $600 (the rode wireless is a decentĀ $200 alternative if they work out the pops)Ā So before I jump into this project, is there anything obvious I'm overlooking? On another note, here's an interesting post from the moto community:Ā https://motovlog.com/threads/why-youre-getting-wind-noise.13605/ Link to comment Share on other sites More sharing options...
houseofjob Posted September 16, 2019 Share Posted September 16, 2019 DIY windmuff dude, dollar store sheet of fur, etc. That and/or you need a different lav that has rejection, as most kits includeĀ omni-directional lavs. Link to comment Share on other sites More sharing options...
Marty Backe Posted September 17, 2019 Share Posted September 17, 2019 I really wonder if you just need a better mic. Here I'm riding my Monster at 25-mph and talking, and the mic is clipped to the outside of my shirt. Unless we have different ideas on what is "unusable", I think this sounds great with very little wind noise. And here's another section where I'm talking and certainly going faster than 20-mph Ā Link to comment Share on other sites More sharing options...

Are you putting the mic completely outside?Ā Link to comment Share on other sites More sharing options...

Are you putting the mic completely outside?Ā In the first video link I was verbally reading my speed, so I know I wasn't going 15-mphĀ Ā Unfortunately, in the above video I can't see whether the mic is outside or inside my shirt I'm going to do a little test just for you, as I'm curious myself. I've only done overlays with my Sony X3000 and it uses the camera GPS which doesn't seem great. Do you have any specific overlay technique (for Android) that I can try?

Just teasing ya~ I'm new to overlays and picked up the GoPro specifically for the 18 Hz GPS (hi @Ben Kim) and the gopro overlays (hi @Mike Sacristan). The workflow is wonky and the GPS lock-inĀ is flakey, but it's great when it works. Outside OEM software,Ā DashWareĀ seems popular, butĀ I haven't tried it yet. The workflow is wonky as well: to get the best quality, you need to export the gauges on a greenscreen, then merge your clip in premiere. I'm surprised there isn't a 1st class plugin solution for after effects /Ā premiere. There is a brute force alternative: screen record wheelog. That presents its own problems toĀ babysit (screen has to be on, isolate the touchscreen, etc). But it work in a pinch for that special highlight, and the audio can be surprisingly good. And my god, who would've thought a 20 second wheelog readout could be so compellingĀ - my heart is racing just watching that againĀ š Link to comment Share on other sites More sharing options...

stephen Posted September 17, 2019 Share Posted September 17, 2019 I bought this for Ā£15 i got sick of wind noise, it sounds ok, im trying different positions to see what sounds best. All these used with the Ā£15 mic plugged into my phone to record the soundĀ Ā Ā Link to comment Share on other sites More sharing options...
