## What is わおん?

See the notes inside your recordings with わおん (WaoN), a visual music transcription workspace for iPhone, iPad, and Mac.

Open an audio file or record directly, then explore its waveform, spectrogram, and detected notes together on one synchronized timeline.

ANALYZE AND EXPLORE

• View the waveform, spectrogram, and detected notes together
• Seek and zoom through the recording
• Adjust playback speed and pitch without changing the source audio
• Set a loop to study difficult passages repeatedly
• Switch between spectrum, overlay, and notes displays

EDIT DETECTED NOTES

• Select and audition individual notes
• Move notes in time or pitch
• Add or delete notes
• Fine-tune pitch, start time, end time, and velocity
• Undo and redo your edits

EXPORT YOUR WORK

• Export detected and edited notes as MIDI or MusicXML
• Automatically estimate key and tempo before export
• Adjust key and tempo manually when needed
• Save exported files or share them with compatible music apps

TRY IT FREE

The free version lets you analyze, edit, and export the first 30 seconds of a recording. A one-time Full Unlock enables complete recordings across iPhone, iPad, and Mac through Universal Purchase. No subscription is required.

PRIVATE BY DESIGN

Audio analysis takes place on your device. No account or sign-in is required, and your recordings are not uploaded for analysis.

わおん is designed for musicians, students, teachers, arrangers, and anyone who wants a visual and editable starting point for music transcription.

## Version history (last 5 releases)

### 1.1.4 — 2026-09-22

- With a connected keyboard, Shift-Space now provides a conventional silent Pause. Space keeps the current sustained Pause behavior, while Shift-Space pauses and mutes. Either shortcut starts or resumes playback with sound.

### 1.1.3 — 2026-09-16

- Fixed audio-reading errors with some MP3 files.
- Improved spectrogram loading and scrolling performance, and fixed an issue where the display could remain blurry after zooming.
- Fixed an issue on iOS/iPadOS 16 where tapping Play or other controls after opening an audio file could activate the wrong button.
- Improved playback, looping, and recovery from interrupted analysis.
- Improved protection of unsaved recordings when replacing audio or moving the app to the background.
- Opening another file now asks you to save or confirm before showing the file picker. Cancelling the picker keeps your recording.
- Improved preservation of note edits when audio is analyzed again.
- Fixed automatic tempo estimation in the analysis workflow.
- Fixed an issue that could reset the timeline when saving a recording on iOS 16.

- Added the shortcut list and usage guidance to Help & About.
- Improved the status bar so note counts and audio details stay readable on one line, with additional information in the details menu.

- Improved playback failure recovery and added diagnostic details to error messages to help identify audio-output problems.
