Features

- Seamless, pitch-accurate loops at each target RPM

How it works
From one recording to a set of loops
Record a sweep
One clean rev-up or rev-down of the engine.
Extract loops
The app tracks the RPM, picks the targets and builds seamless loops at each RPM. Listen to them in the engine simulator.
Export
WAV files at the recording's own sample rate, a pack with a manifest, or straight into Wwise as a blend container with RPM curves.
Free to try. Everything works in the free version except export, so you can hear your own loops before you buy.

Buying again with the same email adds to the same key.
What do I get after buying?
An email within a minute with your license key. Open the app, click the license button at the top (“Free”), enter your email and the key.
What counts as one Vehicle Pass?
The recordings of one vehicle: up to two sweeps (rev-up and rev-down) or up to twelve steady-RPM files, added within 48 hours of the first export with that pass. Exporting them again later is always free.
Where do I get car recordings?
We don't provide any recordings with the app. To test the app you can head over to Soundly and get some high-quality recordings there. Like Mazda MX-5 for example.
Do my recordings get uploaded?
No. Everything runs on your computer. Only the license check talks to our server.
Can I use the loops in commercial games?
Yes. The loops are yours. No attribution needed.
Which Wwise versions?
2021 to 2025, with WAAPI turned on. In the browser, Wwise must also allow https://enginestudio.ultrasonicnexus.com (the app shows how). The Windows app needs nothing.
Do I need the Windows app?
Not really. The web app does everything. The Windows app works offline and is included with Pro and Studio: download it here.
Lost your key?
In the app: License → “Lost your key? Email it to me”.
Refunds?
