なので、大目に見て★★‪☆‪☆‪☆です。

### 3/5 — 使い方が難しいかも

*2025-08-24, version 1.2.1*

音による波形の違いを見たかったのですが、違いが全く見えないように感じました
自分の使い方が違うかもしれません

### 3/5 — ちょっと機能不足かな

*2024-04-28, version 1.2.1*

ぜんぜん反応しなかった

### 2/5 — Uninstalled

*2023-01-28, version 1.2.1*

Wave shape isn’t accurate enough to be very useful. Gets stuck displaying that beating sounds are present when they’re not..

### 5/5 — 自由研究に使用しました

*2023-01-09, version 1.2.1*

どういった演算の結果なのか、窓関数などの詳細が知りたいです。 回答のほどよろしくお願いします。

### 3/5 — Fake/synthesized curve

*2022-12-31*

but the frequencies are useful. The curve is obviously synthesized from the frequency distribution, and not useful for measuring flickering/PWM of LED lights.

### 1/5 — 김지원

노잼

### 1/5 — んー
