Make room for the music.

A small download. A guided setup.

Python and Qt are installed separately. The checker shows what is ready, what is missing, and the commands to install it. Qt includes the playback engine and may need several hundred MB once. FFmpeg adds broad video playback and MP3/video export; WAV works without it.

You’ll review and agree to the download terms before downloading. Public downloads edit local files and have no YouTube downloader.

From download to first song.

Extract the folder. Open the launcher. Follow the checks.

  1. 01

    Check your setup

    Open the launcher below. If Python is missing, it points you to installation instructions.

  2. 02

    Install what’s missing

    Run the commands shown by the checker in your terminal. Dependencies stay in an isolated environment in your user account.

  3. 03

    Rescan & open Studio

    When the required checks pass, open Studio and add your files or a music folder.

Windows setup

Extract the ZIP, then double-click Start SlowMySong.cmd. Keep the extracted app folder. Dependencies are stored separately in your user account.

If Python is missing, install 64-bit Python and reopen the launcher:

winget install --id Python.Python.3.12 --exact

The checker provides the commands for Qt and optional FFmpeg. After installing, click Rescan.

macOS setup & opening warnings

Extract the ZIP. This is a source package for Apple Silicon and Intel; it does not install a signed app in Applications. Open Terminal in the extracted folder and run:

bash 'Start SlowMySong.command'

If Python is missing, install it from python.org or, if you use Homebrew:

brew install python

This preview is not signed or notarized by Apple. Finder may block a downloaded launcher. Apple documents an app-specific Open Anyway option under System Settings → Privacy & Security after an opening attempt. See Apple’s opening instructions. A signed, notarized Mac app needs the publisher’s Developer ID certificate.

Linux setup

Extract the archive. Open a terminal in the extracted folder:

bash slowmysong-studio

The checker lists Python, Qt and optional FFmpeg, with commands for your distribution. On Ubuntu/Debian, Python’s environment support may need:

sudo apt install python3 python3-venv python3-tk

Keep the extracted app folder and reopen the same launcher next time.

Dependency-assisted preview. Package contents and launchers are checked; full app testing for this release was performed on Linux. macOS and Windows still need on-device testing.
