airadio — local AI radio with MiniMax Music 3

airadio is your personal radio station using your local install of ComfyUI and MiniMax Music 3.

It generates ~2-minute songs over ComfyUI’s normal HTTP API, plays them with tail fades, and fills gaps with interstitials or library tracks until the next song is ready.

pip install airadio
# start ComfyUI yourself (with MiniMax Music 3), then:
airadio

Each new song gets a random two-word title that primes generation and becomes the filename (velvet-garden4289.wav).

What you need

1. ComfyUI running locally (default http://127.0.0.1:8188)
2. MiniMax Music 3 installed into that ComfyUI (nodes + model files)
3. Linux playback (pw-play or aplay), ffmpeg / ffprobe, Python 3.10+

airadio does not start ComfyUI for you and does not need comfy-cli or any side “Music 3” client. If it can’t talk to ComfyUI, it tells you to start or install it, then exit.

Install airadio

pip install airadio
# or from source:
git clone https://github.com/Decentricity/interdimensional-radio.git
cd interdimensional-radio
pip install -e .

Install ComfyUI + MiniMax Music 3

Follow the official guides (Music 3 lives inside ComfyUI):

1. ComfyUI — https://github.com/comfyanonymous/ComfyUI
2. MiniMax Music 3 — https://docs.comfy.org/tutorials/audio/minimax/minimax-music-3

That guide covers the model files. Use the low-VRAM INT8 set if you have ~12 GB VRAM (same set this project was tested with).

Start ComfyUI the normal way so it listens on port 8188, then run:

airadio

Optional: keep radio data (library, interstitials, staging) in a custom folder:

export AIRADIO_HOME="$PWD"   # auto-detected if ./library exists
airadio

CLI

How it works

┌─────────┐     HTTP :8188      ┌─────────────────────────────┐
│ airadio │ ──────────────────▶ │ Your ComfyUI + Music 3      │
└────┬────┘                     └─────────────────────────────┘
     │
     ├── library/         saved songs
     ├── interstitials/   gap-fill clips
     └── .radio-staging/  in-flight generation

1. Check — can airadio reach ComfyUI with Music 3 nodes? If not, print install/start help and exit.
2. Pipeline — while a song plays, the next one generates in the background.
3. Fill — if gen is not ready: interstitials, then a library track; repeat.
4. Archive — finished songs land in library/ with catalog metadata.
