Whether a pure exhaust POV is any good is decided by the whole workflow. Capture it clean on the front end and there's something there to sculpt in post; capture it badly and no amount of editing genius will save it. The reverse holds just as well — you can nail the front end and still ruin it by slapping together a careless edit at home, with the volume lurching up and down and the picture out of sync with the sound. That's still a clip nobody wants to finish. The biggest thing I've learned over the years is that the location work and the post work are one continuous pipeline, and you can't drop any segment of it. The most underrated piece, the one almost nobody is willing to spend time on, is the edit at home.
What my whole workflow looks like
When I record a pure exhaust POV, from leaving the house to uploading, the route is always the same: get the gear ready and secure it → set the mic gain → start the camera and the recorder separately → snap my fingers → ride out and capture the sound → go home and align, mix, and export. The first five things happen on location and usually take just a few minutes; the last one happens on the computer, and it's where I put the most thought.
The gear, in one sentence: I capture the sound on a Zoom H2n, shoot the picture on a DJI Osmo Action 4, and the R6 is running an Akrapovič exhaust. That combo has been with me on more rides than I can count, and it just works. Which recorder, which mic is worth buying is a separate question — here I'm only talking about the workflow.
The foundation: I record the sound and the picture separately
Early on I naively figured I'd just buy a slightly better action cam and let one device handle picture and sound at once — so much simpler. It turned out to be nothing like that. The mic inside an action cam is tiny, and it auto-flattens the volume, so the moment you pick up speed it gets completely buried under wind noise. The low-end weight and the layers of the exhaust don't make it onto the recording. My DJI Osmo Action 4 already does about as well as one of these can, but once I'm past about sixty kilometers an hour, all that's left in the picture is the rush of wind and you can barely hear the exhaust itself.
So my approach is blunt: the camera handles the picture only, and I capture the exhaust note separately on a Zoom H2n, then I bring the two back together at home. That way the picture can be the best it can be and the sound can be the best it can be, each on its own terms, neither dragging the other down. Proper film and video have always worked this way: record separately, combine in post. The cost is two machines running on two separate timelines — which is why bringing them back together at home is a step you can't skip.
Splitting them has another upside: once the sound and picture are apart, I can give each one its own ideal settings on location. The camera side only worries about framing and stability, with no need to compromise the angle for the sake of audio; the recorder side can focus entirely on getting the gain, the placement, and the wind protection dialed in. A one-device-does-it-all setup always means both sides settling; separate tracks mean both sides going all the way.
On location 1: placement and mounting (one jiggle ruins the take)
Once the gear is packed, the first thing I do on location is secure the recorder. This is the step that's easiest to overlook and most likely to wreck an entire clip. The recorder only has to jiggle once inside the hip pack and it records a string of low-frequency knocks — "thud, thud, thud" — that you basically can't fix at home. Eight out of ten of the clips I scrapped early on died right here.
I use a hip pack whose inside fits it just right, so the recorder slots in and doesn't slide; if it still moves, I pack foam blocks all around it until it's locked in place — my rule is always too tight rather than too loose. The foam costs nothing — the padding inside packaging, or the kind that comes in a camera case, cut to size, does the job for basically free. Before I head out I always give it a press to confirm it doesn't budge at all in there.
For position, I put the recorder on the leeward side behind my body, with the mic facing the tail of the bike, going the same direction as the airflow — so the wind flows past it rather than blasting straight into the capsules. People often ask which way the mic should point: go with the wind, don't let it slam into the opening. Pair a furry windscreen with the right placement and you've already cut a big chunk of the on-location wind noise. I mostly do short POV trips, so once this placement is set when I get on the bike it stays put — I rarely need to adjust it along the way.
I've seen the cautionary version too many times: the hip pack isn't packed tight, the whole recording is riddled with rhythmic low-frequency knocks, and that knocking frequency happens to overlap with the engine's vibration, so no matter how you try to pick it out with EQ or noise reduction in post you can't get it clean — and the whole section ends up in the bin. So when I secure it I'd rather err on the tight side and never leave even a sliver of room to shake. This is the kind of noise no edit at home, however good, can patch back together; you can only avoid it on location.
On location 2: setting the mic gain
Once it's secured, there's one more thing I have to do before setting off: set the gain. This step directly decides whether you'll clip. The louder the exhaust, the lower you set the mic gain. My Akrapovič isn't exactly quiet, so I run the gain a lot lower than most people would guess. Set the gain too high, hit a loud exhaust, and the moment a peak slams into the ceiling you get that ripping, torn noise — and because it's digital distortion, once it's broken it's broken, and there's nothing post can do about it.
Every time, before setting off, I blip the throttle once or twice in place and do a test recording, eyes on the recorder's meter, watching whether it's slamming the top. If it isn't maxed out and there's still a little headroom, then I go. Blipping in place has a built-in limitation, though — what I want to capture is the high-rpm part of the note, but standing still you can't possibly rev that high, and the decibel gap between a stationary blip and actually pulling high rpm is large. So this in-place test is only a rough safety check; whether it's actually right I only know once I've done a ride and opened the file at home to look at the real waveform and peaks.
So how much mic gain to run took me a while to settle — I got there by trying lots of settings, bringing them back, listening to each one and checking each one's dB, and slowly converging. Every bike's sound and every day's conditions are different; there's no single number you can just hand everyone. On my Zoom H2n, my mic gain sits roughly between 0 and 1, a range that keeps the peaks from getting too high and holds onto some headroom. The principle is better-too-quiet-than-clipped: record a little low and you can still bring it up in post; clipped distortion is permanent damage, and no amount of pulling it up changes that it's broken. Every brand of mic compresses differently inside, so the most reliable approach is to look at the actual dB values in the recorded file and fine-tune from there. When I switch bikes or pipes I take the last setting as a baseline and just nudge it a little.
On location 3: snap your fingers before you roll
Once the camera and the recorder are both rolling, the last thing I do before setting off is snap my fingers. The sound and the picture are recorded on two separate machines, so you have to bring them together at home. If you do it by ear, nudging frame by frame, it'll make you question your life choices — that's how I slogged through it early on. Once I learned this trick the whole thing got easy. It's exactly the same principle as the clapperboard that goes "clack" on a film set: make one clear point so the picture and the sound have something to align to.
I snap my fingers once, right in front of the lens. That snap leaves a very sharp waveform spike on both tracks at the same instant. In the edit, drag the spikes on the two tracks into alignment and the picture and the sound are synced. It takes two seconds — it shrinks the cost of recording separately down to a single drag of the mouse at home.
I use a snap rather than a clap because a snap is short and sharp — on the waveform it's a single, clear peak you can spot at a glance; a clap or speech makes a blurrier, more spread-out waveform that's harder to match. If you're wearing gloves and can't snap, a firm slap on the tank or your helmet works too — same principle: make a short, clear sound to use as the alignment marker. I mostly do short trips and the clips aren't long, but I've never once skipped the snap, because the two seconds you save get paid back tenfold at home.
That's the end of the on-location part. Everything left happens on the computer.
At home: edit, mix, align, export
A lot of people think editing just means trimming the head and tail and tossing it online — which is exactly why so many clips that were captured perfectly fine on location still end up tiresome to listen to. For me, this part at home is where raw material becomes a piece of work, and all the location effort beforehand exists to let this part be done well. My whole post process is four moves: align → shape the sound → balance the level → confirm, then export.
1. Align: sync the picture with the exhaust note first
The first thing I do at home is lay the camera's picture and the exhaust note from the Zoom H2n onto the same timeline. I pull both audio tracks into the editor and find that snap spike at the start — the camera's track has sound on it too, so there's a spike there as well — and drag the two spikes into vertical alignment, and the whole section is synced. After aligning, I usually pick a point with an obvious change (say, the instant of a throttle blip) and double-check it once more, confirming it doesn't drift further and further off over the length of the clip. Cut corners on this step and it doesn't matter how well you mix afterward — viewers will spot in a second that the gear, the action, and the sound don't line up. Once it's aligned, I mute or delete the camera's own muddy audio track and keep only that clean exhaust note from the H2n.
2. Shape the sound: I barely touch EQ
A lot of people expect this step to be all EQ work. I barely touch it — what I'm after is getting the sound as close as possible to what I actually heard on the bike in the moment, and moving too much only fakes away that sense of reality. I edit in Final Cut Pro, and shaping the sound mostly comes down to two things: loudness and pan, using those two for fine adjustments to slowly get it how I like it. I almost never use a low cut — the moment you shave the low end, the exhaust starts to sound off at low rpm and loses that block of weight, so unless a section has wind noise bad enough to ruin the material, I'd rather leave it alone. If it can stay untouched, I leave it untouched; the original sound is usually the right one.
3. Balance the level: so people can listen start to finish without touching the dial
Next is balancing the volume across the whole clip. The worst thing a clip can do is lurch loud and quiet, forcing the viewer to keep adjusting — I can't sit through that kind of clip myself either. I push the whole thing to one consistent, comfortable level, so the high-rpm parts that should be loud hit with impact and the off-throttle moments don't suddenly vanish. If I need to, I'll use a very light touch of compression to rein in the most jarring peaks just a little, but again only as far as needed — I want the dynamics, not to squash it into a dead, flat line. When it stays steady to the ear from start to finish, that's when a clip earns the kind of listenability you can just leave running.
4. Confirm, then export: format, sample rate, one last listen-through
Before exporting I always listen through one more time from start to finish, confirming no section suddenly gets louder or quieter, that there's no stray noise I missed, and that the alignment hasn't drifted — only then do I export. On format there are two things I'm firm about: record in lossless WAV rather than MP3 — WAV keeps the full dynamics intact, which leaves room to fine-tune and raise the level in post, whereas MP3 is lossy compression that breaks easily the moment you touch it. I record at a 96kHz sample rate to keep a little extra resolution in hand, then conform to whatever the video needs on export. Memory cards are so cheap now — don't sacrifice sound quality to save that little bit of space.
Across the whole post process I hold to one overriding rule: just enough, no over-processing. I don't add music, sound effects, or voiceover — to me the exhaust note is the content, and anything extra only steals its spot. The cleaner the post, the closer it sounds to what it originally was.
Please, wear headphones when you edit. Computer speakers can't reveal the detail in the low end or those subtle bits of noise; only with headphones can you pin down what needs fixing, where the level has drifted, and whether the alignment is off. From recording to editing, I judge the entire process by headphone — which is the same reason I keep telling everyone to listen to my clips with headphones on.
A few pitfalls I fell into myself
These are pretty much the ones every beginner hits, and I was no exception. The first two are on location and the last two are in post:
1. The hip pack is too loose and the recorder slides around inside. The whole take records low-frequency knocks you can't fix at home. The hip pack size has to fit snugly; if it's not snug enough, lock it in with foam blocks.
2. Mic gain set too high. With a loud exhaust, a single blip of the throttle clips it. Always test-record and watch the meter before you set off — it's a step I never skip.
3. Forgetting the snap, then losing my mind aligning at home. Without that spike for a marker, you can only feel out the picture and sound by ear, which takes several times longer. Make "snap as soon as I start rolling" muscle memory and you'll never fall into this one again.
4. A heavy hand in post. Early on I couldn't resist cranking the EQ and squashing the volume flat, and the more I tweaked the more fake and lifeless it got. I only later understood that with material captured well on the front end, the best-sounding result comes from a light touch in post that keeps its original character. A lot of editing skill lives in "holding yourself back from touching it."
The recording rig on my bike
I've run the same setup on my bike for years: the H2n for sound with a dead-cat fur windscreen on it, and the Osmo Action 4 for picture. Those three are all it takes to record a pure exhaust POV from start to finish. The second card is the DJI Mic 3. I haven't used it, but its numbers fit recording exhaust, so take a look if you'd rather not carry a separate recorder.
Zoom H2n Handy Recorder (Amazon Renewed)
Every exhaust note I record comes off an H2n: mic gain at 0 to 1, WAV at 96 kHz, tucked in a hip pack under a dead-cat fur windscreen. After the H2n was discontinued, I bought Zoom's newer H2essential to try. It won't let you adjust mic gain, and every blip of the throttle clipped like crazy, so I'm still recommending the H2n. Amazon no longer has new units, and this link goes to an Amazon Renewed unit, the same model that's on my bike. If you want to run my 0 to 1 gain setting and copy the whole workflow as is, get this one.
Pros
- A physical mic gain knob; I keep it at 0 to 1, which leaves headroom even at full throttle
- Five built-in mics, switchable between XY and MS
- WAV up to 24-bit/96 kHz, the same setting I record exhaust at
- Runs on two AA batteries, easy to swap when they die
Cons
- A renewed unit, so it isn't brand new
- Discontinued, and Amazon has no new units
DJI Mic 3 Transmitter (Single TX)
I haven't used this one myself, but I've seen what other people recorded with a DJI Mic and it came out fine. What draws me to it is how many of its numbers line up with recording exhaust. Max SPL is 126 dB, 6 dB more than the 120 dB of the H2n and H2essential. Input gain is manual, and you can change it right on the Action 4. A single TX pairs wirelessly with the Osmo Action 4 with no receiver, so the sound goes straight into the camera and you don't even need the finger snap to line things up at home. The TX also has 32 GB on board and can record a 32-bit float copy internally at the same time, so you get a backup too.
Pros
- 126 dB SPL max, 6 dB above the 120 dB of the H2n and H2essential
- Manual gain, adjustable from the Action 4, the receiver, or the DJI Mimo app
- A single TX links to the Action 4 with no receiver, so sound lands in the camera and there's no snap to align
- 32 GB built into the TX for a simultaneous 32-bit float backup, and a fur windscreen comes in the box
Cons
- Records mono into the Action 4 at 48 kHz, different from the 96 kHz I'm used to
- 126 dB is still a ceiling, so it'll clip if you put it too close to the exhaust tip
YOUSHARES H2n/H4n Dead Cat Fur Windscreen
The H2n ships without wind protection, so a furry cover is the first thing to add before you ride. My own H2n always wears a dead-cat fur windscreen, and with the placement sorted, that's how I keep wind noise down at speed. Slip it on and a big chunk of that rushing wind drops away as the speed climbs; placement takes care of the rest. This one is cut to the H2n/H4n body, so it doesn't sag or slide off the mics. You get the cover alone with no shock mount, so vibration coming through the body depends on how you mount the recorder.
Pros
- Cut for the H2n/H4n, so it sits snug without slipping
- Takes most of the worst wind noise off at speed
- Just the cover, so you don't buy a whole kit to get wind protection
- Packs small and fits easily in a hip pack
Cons
- Cover only, no shock mount
- Sheds over time, so check it isn't leaving fur on the mics
DJI Osmo Action 4 Action Camera
Those first-person riding shots in the videos are all from this camera. Its audio is nothing but wind past sixty, so I never count on it for the exhaust — it handles one thing: getting the picture steady and good-looking. This generation's sensor performance under harsh light swings — backlight, ducking in and out of tunnels — is the main reason I keep it around; paired with the body stabilization, short POV trips get that hugging-the-tarmac sense of being there. Sound to the H2n, picture to this — each maxed out on its own.
Pros
- Large sensor holds up under backlight and tunnel light swings
- Strong body stabilization — short POV trips stay steady
- Weatherproof body — no extra housing needed for outdoor rides
- Battery life plus magnetic quick-release — fast swaps and top-ups
Cons
- Built-in audio drowns in wind at speed. Record the note separately
- The wide angle has fisheye distortion — fix it in post if it bothers you
FAQ
What are the steps to record a pure exhaust POV from start to finish?
Six steps: get the gear ready and secure it before you leave, set the mic gain, start the camera and the recorder separately, snap your fingers in front of the lens once they're both rolling, ride out and capture the sound, then go home and align, mix, and export. The first five happen on location and the last one happens on the computer — and the edit at home is the part that decides whether the final clip is any good.
What do you actually do in the edit at home?
Four moves: first I use the finger-snap spike to line up the picture with the exhaust note, then I shape the sound in Final Cut Pro using loudness and pan until it's how I like it (I barely touch EQ), then I balance the volume across the whole clip, and finally I listen through from start to finish to confirm the level is consistent before I export. No music, no sound effects, no voiceover.
The picture and the sound are recorded separately — what's the fastest way to sync them at home?
The finger snap you do when you start rolling. It leaves a very sharp spike on both tracks at the same instant; in the edit you drag the two spikes into alignment and the picture and sound are synced — far faster than nudging frame by frame and matching it by ear. It's the same principle as a clapperboard on a film set.
Which software do you edit in, and how do you treat the sound?
I edit in Final Cut Pro. I barely touch EQ on the sound — I mostly do fine adjustments with loudness and pan to get it how I like it. I almost never touch a low cut, because the moment you shave the low end the exhaust starts to sound off at low rpm — unless a section really does have too much wind noise, I'd rather leave it natural. I record at a 96kHz sample rate.
Do you have to wear headphones when editing?
You have to. Computer speakers can't reveal the low-end detail or the subtle noise; only with headphones can you pin down what needs fixing and where the level drifts. I rely on headphones to judge the whole process, from recording to editing.
