Exhaust Note is not an app that plays back engine recordings. It synthesizes the sound from scratch, every moment, from the firing order created by cylinder layout and crankpin phasing. Why a crossplane V8 rumbles, why a flatplane screams, why a V12 idle throbs — it all comes from the physics of firing intervals. This app computes that physics in real time. ■ Real-time synthesized exhaust - Zero recorded samples. Crank-angle integration → per-cylinder firing → exhaust-pipe propagation, computed every sample - Distinct primary pipe, mid-pipe and muffler model for every engine - Muffler continuously adjustable from straight pipe to quiet ■ Engine collection - Presets from inline-3 to V12, based on real-car specs - Crossplane vs flatplane V8 — same eight cylinders, completely different sound - Firing order and rumble index shown as specs ■ Pop and bang + flames - Afterburn pops on throttle lift and downshifts - Flames at the 3D exhaust tips, same instant and same bank as the sound ■ Tunnel mode - Reverb that wraps the sound in wall reflections, like driving into a tunnel ■ A living 3D machine - Crankshaft, pistons and connecting rods rotate in phase with the sound - Gearbox cutaway: constantly meshed gear pairs and real synchro-sleeve movement - Observe the mechanism at 1/10 slow motion, or switch to real time for phase match ■ The feel of driving - Torque-converter launch, rev matching, manual H-pattern shifter - Haptics on rev limiter, wheelspin, shifts and ABS - Analog pedals: press position controls pedal travel Built by a gearhead, for gearheads. ## Key features - Real-time synthesized exhaust sounds - Adjustable muffler settings - Diverse engine presets - Pop, bang, and flame effects - Living 3D engine animation - Driving feel simulation - Tunnel reverb mode ## Recent user reviews (2 of 2) All indexed reviews: https://appshunter.io/ios/app/exhaust-note-engine-sound-sim/id6797558385/reviews.md ### 5/5 — Amazing game *2026-09-02* 10 out of 10 can’t wait for more engines ### 5/5 — Good *2026-08-30* This is GREAT, it’s exactly what i wanted for so long, you guys should also make it so you can turbo or supercharge the engines or make it so you can change the horsepower ## Frequently asked questions about Exhaust Note ### Does Exhaust Note have ads? Yes, Exhaust Note contains advertisements. It is a free application supported by ads. ### What is the age rating for Exhaust Note? Exhaust Note has an age rating of 4+ and is suitable for a wide range of users. ### How often is Exhaust Note updated? The latest version, 1.3.0, was released on 2026-09-05, indicating recent development and updates. ### What devices does Exhaust Note support? Exhaust Note is available for iPhone and iPad devices. ### Can I adjust the exhaust sound in Exhaust Note? Yes, the muffler is continuously adjustable from straight pipe to quiet, allowing for a wide range of sound customization. ### Does Exhaust Note use recorded engine sounds? No, Exhaust Note synthesizes sounds from scratch using real-time computation based on firing order and physics, rather than playing back recorded samples. ### What is 'Tunnel mode' in Exhaust Note? Tunnel mode adds reverb to the sound, simulating the effect of wall reflections experienced when driving into a tunnel. ### How does the 3D engine animation work in Exhaust Note? The 3D machine features a rotating crankshaft, pistons, and connecting rods that move in phase with the synthesized sound, offering a visual representation of the engine's mechanics. ## Version history (last 5 releases) ### 1.3.0 — 2026-09-05 Drive the new circuit yourself. • Added a figure-eight circuit inspired by Suzuka, with a grade-separated bridge crossing and 30 m of elevation change. • Lap and sector timing with a saved personal best, replayed as a translucent ghost. • Reverse gear lets you back away from the barriers. • Photo-based materials on the track surface, run-off and grass. • Fixed the car appearing to jump back and forth while steering. • The whole circuit screen is now translated into ten languages. ### 1.2.1 — 2026-09-04 A deeper, fuller exhaust note. • The bass slider now lifts the low end evenly across the rev range instead of only at certain RPMs. • Large-displacement engines get a longer blowdown per cylinder for a thicker body. • Mechanical noise that sounded harsh at high revs has been smoothed out. • Fixed phase cancellation that could make the bass thinner as you turned it up. ### 1.2.0 — 2026-09-03 Faster pedal response. • Touches are read directly with no gesture arbitration, so the sound starts the moment you press. • In analog mode, a light press near the bottom of the pedal now opens at least 15%, removing the dead zone. • An ad may occasionally appear when you change the engine or transmission. ### 1.1.0 — 2026-08-26 Four new engines and four new transmissions. • Flat-4 — opposing cylinders don't share a crankpin, so one bank fires twice within 180° and then waits 540°. The most uneven engine in the app. • Flat-6 — same layout, but each bank fires evenly every 240°, so there's no rumble. • V6 — the crankpin has to be split by 60° for the firing to come out even. • V10 — the bank angle lands exactly right, so it's even without a split pin. Added a 6-speed sequential dog box, 8-speed dual-clutch, 5-speed manual and 4-speed automatic. The sequential shifts in 0.05s by cutting ignition instead of the clutch. Settings now has Bass. It tunes the resonance of the empty volume inside the muffler — exhaust bass comes from chamber size, not pipe length. ### 1.0.1 — 2026-08-11 Stability improvements and minor bug fixes. ## More apps by seihee han - [꾸쥬워마이걸](https://appshunter.io/ios/app/id629944904) - [Free Rider: Salary Counter](https://appshunter.io/ios/app/free-rider-salary-counter/id856744544) - [영어하자 - AI 전화영어, 단어장, 영어회화, 퀴즈](https://appshunter.io/ios/app/ai/id6760590621) - [픽미주 - 미국주식 시세, 포트폴리오](https://appshunter.io/ios/app/id6760827610) - [Muka - Silent Camera](https://appshunter.io/ios/app/muka-silent-camera/id6786973652) - [Thocky — Keyboard Sounds](https://appshunter.io/ios/app/thocky-keyboard-sounds/id6788026754) All apps by seihee han: https://appshunter.io/developer/629944907 ## Related topics [turbo sound](https://appshunter.io/ios/topics/turbo-sound) · [engine simulator](https://appshunter.io/ios/topics/engine-simulator) · [k machine audio visual engine](https://appshunter.io/ios/topics/k-machine-audio-visual-engine) · [car sounds](https://appshunter.io/ios/topics/car-sounds) · [truck sounds](https://appshunter.io/ios/topics/truck-sounds) · [engine](https://appshunter.io/ios/topics/engine) · [engine rpm](https://appshunter.io/ios/topics/engine-rpm) · [engine builder](https://appshunter.io/ios/topics/engine-builder) · [cobra hd exhaust sounds](https://appshunter.io/ios/topics/cobra-hd-exhaust-sounds) · [manual transmission](https://appshunter.io/ios/topics/manual-transmission) · [engine pistons asmr](https://appshunter.io/ios/topics/engine-pistons-asmr) --- *Data collected daily from the US App Store and indexed by [AppsHunter](https://appshunter.io/).
