## What is WorldSounding?

WorldSounding gathers the music of the WorldMusic series into one app. Listen to each piece, play it with your fingers, and layer several at once. Sounds are synthesized on the spot or stretched from their material, so the performance never repeats.

- WorldTuning — an eternal drone that begins with an orchestra tuning up.
- WorldShifting — timeless minimal music in which repeating short patterns drift apart and overlap.
- WorldWandering — infinite granular music that stretches sound to extremes and repeats short fragments.
- WorldRushing — harsh music in which a beautiful melody drifts through one mass of layered, distorted roar.

The bar at the top shows every piece and whether it is sounding. Tap a name to bring it to the screen, where you can also change the performance. A piece keeps playing when it is not on screen, and there is no limit on how many can sound together. Turn on Dual Display to show two pieces at once.

You can also fit layered pieces together. Each piece can match a shared tempo and a shared pitch, and follow the chord tones of another piece. Every piece switches these on and off on its own, and notes that do not agree can bring surprises.

Each piece keeps its own screen: touch the picture to travel, shape the sound in the Sound sheet, and let it wander on its own. Send the sound to Bluetooth speakers, AirPlay speakers such as HomePod, or a USB audio interface, and control everything from Control Center and the Lock Screen. Record exactly what you hear, every piece together, as a 48 kHz / 24-bit WAV file.

The built-in microphone can also listen to the sounds around you. The app analyzes them and makes the result the reference pitch of the performance. The sound is analyzed on this device: nothing is recorded, and nothing is sent. While Listening is on, AirPlay speakers cannot be chosen.

WorldSounding is free with a banner ad, and every feature, including the Sound sheet and settings, is available. A piece you have not bought plays for three minutes each time you open the app. Each piece is a one-time in-app purchase that removes the limit for that piece, and buying any one removes the ad. The 4-Piece Set also lets you buy all four together.

## Version history (last 5 releases)

### 2.0.0 — 2026-11-03

- WorldTuning is now WorldSounding, an app that gathers the music of the WorldMusic series. WorldShifting, WorldWandering and WorldRushing join WorldTuning.
- Layer as many pieces as you like, and show two at once with Dual Display.
- Each piece can follow a shared tempo, a shared reference pitch, and the chord tones of another piece.
- Recording now captures every piece that is sounding.
- Every setting is now free, including recording and Listening. The difference is playing time: a piece you have not bought plays for three minutes each time you open the app.
- If you bought Pro, thank you. It carries over as the 4-Piece Set: no limit on all four pieces, and no ads.

### 1.3.0 — 2026-10-30

- Supports iPhone Duo. When there is a vertical bar, the four buttons move into it.
- The picture always flows upward on a tall screen and from right to left on a wide one. When you turn the device, the button symbols and the sheets turn to stay readable.
- The volume is now matched to other music apps (−16 LUFS on average).
- The Sound and Settings sheets each remember their height and scroll position. On iPad, sheets can now be resized by dragging.

### 1.2.1 — 2026-09-22

- Adjusted the first launch and Reset to sound closer to an orchestra tuning up.

### 1.2.0 — 2026-09-21

- Listening (Pro): WorldTuning now hears the sounds around it — a whistle, a voice, an instrument, another iPhone playing WorldTuning — and tunes its own reference pitch to the pitch it hears.
- It leaves out the sound it is making itself. Turn that off to hear how much of it remains.
- The reference pitch with its note name, and meters for the microphone and the speaker, appear at the bottom of the screen. They can be hidden in Settings.
- The sound is analysed on this device. Nothing is recorded, and nothing is sent.
- While Listening is on, iOS plays the app as one that uses the microphone: the performance sounds somewhat different, the volume no longer goes all the way down, and AirPlay speakers such as HomePod cannot be chosen. Turn Listening off to get them back.

### 1.1.0 — 2026-09-16

- A new icon.
- The journey now runs along one loop of eight places, quiet at the bottom and busy at the top: Solitude, Stillness, Calm, Vertigo, Tuning, Weighty, Radiant and Rhythm. Touch a name to hear that place at its most characteristic. The top and bottom are joined, so the sound carries straight on across them.
- Tuning now recreates a real orchestra tuning up, and the oboe's A can come at a steady interval.
- New sound controls: Reference timing, Detune, Air and grain, Character and Partial stretch.
- Choose how the performance ends: Cut off, Fade out, One by one, Let ring, Final accent, High to low, Low to high or Random ending.
- Knock three times on the picture to stop or start the performance.
- Audio Output: play through Bluetooth speakers, AirPlay speakers such as HomePod, or a USB audio interface. The performance also appears in Control Center and on the Lock Screen.
- Recording: save exactly what you hear as a 48 kHz / 24-bit WAV file.
- Pro, a one-time purchase, removes the ad and unlocks every setting and recording. If you bought Remove Ads, you already have Pro.
- The bottom band of the Sound sheet opens and closes, Auto Journey can take much smaller steps, and the performance no longer stops on first launch.
