Tranquillity Maker

Tranquillity Maker plays several of Apple’s Background Sounds together. Each sound has its own volume, so you can make a mix and return to it later.

Install the Mac app

After buying, connect your GitHub account in Polar and accept the repository invitation. Download the Mac app from the customer releases, unzip it, and move it to Applications. You need macOS 15 or later.

The Mac download is signed and notarized. Open it normally from Finder and confirm macOS’s first-open prompt.

The purchase also includes source code. The iPhone and iPad version is a source build you install with Xcode, rather than an App Store download.

Make your first mix

Try a quiet combination of Rain and Fire:

1. Open the main window and find Rain.
2. If the sound has a Download button, download it first. Sounds already installed on your Mac can play immediately.
3. Turn Rain on and set its slider to a comfortable level.
4. Turn Fire on and lower its individual volume until it sits behind the rain.
5. Adjust the master volume for the whole mix.

Turn a sound off to remove it from the mix. Sounds fade in and out, and the app crossfades between their audio segments while they play. Your selected mix and volume levels are remembered between launches.

The app can play multiple sounds at once. Download only the ones you want to try; the app shows download sizes for sounds it needs to fetch.

Pause and resume

Use Play to resume your last mix. Press Space while the window or menu bar panel is open to pause or resume.

The keyboard’s media play/pause key can control the mix from another app when Tranquillity Maker was the last app playing media. Another media app may take over that key.

Click Tranquillity Maker’s menu bar icon to open the mixer without bringing up its main window. The icon changes while something is playing. You can adjust the same mix from either place.

When you connect headphones or switch output devices, playback follows the system audio output. If you hear nothing, check the selected output, macOS volume, the master volume and each enabled sound’s slider.

Downloads and offline listening

The app contains no audio files. It uses installed macOS Background Sounds where available and downloads missing sounds directly from Apple.

Downloaded Mac sounds live in:

~/Library/Application Support/Soundscape/Sounds

They can play after downloading without fetching the files again. The app checks Apple’s sound catalog when launched. A catalog or download problem can affect new sounds without meaning your volume settings are wrong.

Use the sounds for listening on your own supported Apple devices. They belong to Apple; purchasing the app’s source code does not give you rights to redistribute the audio or put it in recordings.

iPhone and iPad source build

To install the included iPhone/iPad source, open Soundscape.xcodeproj in Xcode and choose the SoundscapeiOS scheme. Connect and unlock your device, select it as the destination, and choose your signing team under Signing & Capabilities. Run the project with ⌘R.

If Xcode asks for Developer Mode, follow its device setup instructions and run the project again. The source targets iOS 18 or iPadOS 18 and later. Installation and signing use your own Apple account.

On the device, tap a sound to enable it and use its slider for volume. Downloads stay in the app’s storage. Playback can continue with the screen locked, and Play resumes a mix paused by a call or Siri.

The repository also contains experimental Apple TV source. It is not a ready-to-install TV download; consult the repository’s current platform and audio-license notes before using that target.

Updates

Download new Mac versions manually from customer Releases and replace the installed app. Existing public update checks cannot access private releases. Keep the source checkout if you build the optional device versions yourself.
