### 5/5 — 鼻歌の音階を視覚化できる

*2023-10-22*

鼻歌を音階として視覚化できるので、楽器が弾けない人でも、口ずさみながら作曲したメロディーを楽譜やMIDIにすることがやり易くなります。

例えば、ふと浮かんだメロディーをiPhone純正のボイスメモに録音している場合、ボイスメモの共有機能でこのアプリを選択すると、ボイスメモの録音データがこのアプリに転送され、音階として視覚化できます。

このアプリは単純に音階位置をざっくりと表示するだけなので、解析結果をデータとして出力できないのが非常に残念です。

精度はおおよそで構いませんので、MIDIデータとして出力できるようになれば最高なのですが。

**Developer response:** アプリをお使いいただき誠にありがとうございます。
すでにアップデートにより、MIDIデータの出力が可能となっております。お試しください。
