AirPlay audio receiver module for Move Anything on Ableton Move

README from GitHub, MIT

Move Everything - AirPlay Receiver

An AirPlay audio receiver module for Move Everything on Ableton Move hardware. Stream audio from your iPhone, iPad, or Mac directly to Move's signal chain.

Features

  • AirPlay 1 receiver using shairport-sync (cross-compiled and bundled)
  • Broadcasts as "Move - Slot N" on the network (slot number auto-assigned)
  • Chainable sound generator — works in the Signal Chain with audio FX
  • Gain control exposed to Shadow UI knobs
  • Zero device-side dependencies beyond what Move Everything provides (avahi, OpenSSL)

Requirements

  • Move Everything host (v0.3.0+)
  • avahi-daemon running on the device (standard on Move)
  • WiFi network shared between Move and the AirPlay source device

Build

./scripts/build.sh

Builds via Docker. Cross-compiles both shairport-sync (ARM64) and the DSP plugin. Output: dist/airplay-module.tar.gz.

Install

./scripts/install.sh

Deploys to /data/UserData/move-anything/modules/sound_generators/airplay/ on the device.

Usage

  1. Load the AirPlay module in a Signal Chain slot
  2. On your iPhone/iPad/Mac, open AirPlay output picker
  3. Select "Move - Slot 1" (or the appropriate slot number)
  4. Audio streams through the chain — add audio FX, adjust gain, etc.

Architecture

The DSP plugin (airplay_plugin.c) follows the same pattern as the Webstream module:

  1. Creates a named FIFO at /tmp/airplay-audio-<pid>
  2. Generates a shairport-sync config and spawns it with the pipe backend
  3. shairport-sync registers via avahi mDNS, receives AirPlay audio, decodes ALAC, writes raw S16LE stereo 44100Hz PCM to the FIFO
  4. render_block reads from the FIFO into a ring buffer and outputs audio

Bundled shared libraries (lib/) provide libconfig and libavahi-client for devices that don't have them.
