Forza Designer Radio Maker

Build a custom radio station for Forza Horizon 6 from one of three sources, give it a name and logo, and hand the prepared bundle off to the FH6 Radio Tool for in-game replacement.

Features

• Spotify Radio — paste a public Spotify playlist URL; track titles + artists are read from the playlist's embed page, then audio is fetched from the top YouTube match per track.
• YouTube Radio — paste a YouTube playlist or video URL; audio is downloaded directly.
• Custom Station — pick your own local audio files (mp3 / wav / flac / m4a / opus / aac / ogg / wma).
• Every station gets its own name and logo (or a branded placeholder is generated automatically).
• Audio is normalized to 16-bit 48 kHz stereo PCM WAV — the format the FH6 Radio Tool expects.
• One-click launch of the FH6 Radio Tool with:
  • the bundled Fmod Bank Tools auto-extracted and pre-configured,
  • the FH6 Radio Tool's UI forced to English,
  • the music-folder path copied to your clipboard ready to paste.
• yt-dlp.exe is fetched on first use from the official GitHub release into %LOCALAPPDATA%\ForzaHorizonRadioMaker\bin\ so the app stays small and yt-dlp stays current.

Install / run from source

Requires Python 3.10+ on Windows.

setup_env.bat        :: one-time: create .venv and install deps
run.bat              :: launch the app

Build the EXE

build_exe.bat

Produces dist\ForzaHorizonRadioMaker.exe (one-file, windowed). The Fmod Bank Tools zip in forza_radio_maker\resources\ is bundled into the EXE and extracted to %LOCALAPPDATA%\ForzaHorizonRadioMaker\fmod_bank_tools\ the first time you launch the FH6 Radio Tool from inside the app.

How a build flow looks

1. Pick a mode (Spotify / YouTube / Custom).
2. Enter the URL or pick local files.
3. Type a station name and (optionally) pick a logo image.
4. Click Build station. yt-dlp is downloaded the first time; tracks are fetched and converted to WAV.
5. On the success screen click Launch FH6 Radio Tool… — the app:
   • extracts and registers Fmod Bank Tools on first run,
   • flips the FH6 Radio Tool's UI to English,
   • copies the prepared music/ folder path to your clipboard,
   • launches the FH6 Radio Tool.
6. In the FH6 Radio Tool: paste the path into its Music folder field, select your target radio station slot, validate the audio, then Generate Mod Output Package or One-Click Replace.

Notes

• The FH6 Radio Tool is a separate program. The app auto-detects common install locations (Downloads / Documents / Desktop / Program Files) and remembers the path between sessions in %LOCALAPPDATA%\ForzaHorizonRadioMaker\settings.json.
• Spotify integration scrapes the public embed page — no API key needed, but the playlist must be public.
• yt-dlp updates frequently. If downloads start failing, delete %LOCALAPPDATA%\ForzaHorizonRadioMaker\bin\yt-dlp.exe and relaunch — the latest release will be fetched automatically.
• ffmpeg ships via the imageio-ffmpeg Python package; no separate install required.
