## What is Sonir?

Air recording × acoustic measurement × comparison. Sonir is a tool for recording the air, measuring acoustics, and comparing your takes.

"It sounded good" doesn't help you next time. Mic position, level, room, gear: change one and the recording is different. Sonir is built for reproducibility and side-by-side comparison.

Features:
- Measurement: SPL / RTA / FFT, and sweep-based impulse response (RT60, frequency response, waterfall)
- Air recording & recording score: score a take on multiple axes and share it as a comparison card
- Comparison: overlay recordings and spectra, and switch between them
- Full metadata: gear profile + calibration + room tags, so any take can be revisited under the same conditions

Record, measure, compare. Reproducible measurement from your very first take.

Every feature is free. No in-app purchases, no subscription, no ads.
