Thanks to everyone who jumped on the TestFlight beta — your feedback shaped this release.
For those just seeing this: ampMeasure is a native macOS app that drives the QA403 directly over USB — no Windows or virtualization needed. Just plug in and measure from your Mac.
What it does:
- THD / tone analysis
- IMD analysis
- Frequency response
- Power sweep
- Oscilloscope + spectrum views
- Data export
Requirements: macOS 26, Apple Silicon & Intel
Minimum requirement will be lowered in next version to macOS 15 after successful beta testing.
The TestFlight beta stays open for anyone who wants early access to upcoming builds — I’ve got a 1.0.1 update in the works (averaging hold, chirp averaging, a few UI refinements). If you’d like to help test, the beta link is still live:
Feedback and feature requests very welcome — this is actively developed and I read everything here.
