### 1/5 — Не работает

*2025-04-06*

Что за барахло не работает нифига

### 2/5 — Problem

*2024-08-27*

I installed this thinking it would help me get the right frequency sound for a given piano note. 
What I get is one note, then the frequency glides up to another note then stabilises. 
I am doing something wrong?
I didn’t think this should happen?
Am uninstalling after 5 minutes.
