Auxfeed is open source. If something's broken or unclear, the best place to get help is GitHub Issues — where bugs get fixed, not just answered.
You need two things: the Auxfeed DAW plugin installed on a Mac running your DAW (Pro Tools, Logic, Ableton, etc.), and the Auxfeed iOS app on your iPhone or iPad.
For local monitoring, both devices must be on the same Wi-Fi network. For remote monitoring from anywhere, you'll also need a relay server — you can self-host the open-source Node.js relay on any VPS.
Any DAW that supports AU, VST3, or AAX plugin formats on macOS. This includes:
Pro Tools (AAX), Logic Pro (AU), Ableton Live (VST3/AU), Reaper (VST3/AU), Cubase / Nuendo (VST3), Studio One (VST3/AU), and others.
The plugin advertises itself on your local network using Bonjour (mDNS). The iOS app uses NWBrowser to discover Auxfeed streams automatically — no IP address entry needed.
Just open the app on your iPhone while the plugin is running in your DAW and your session will appear. Tap to connect.
PCM Lossless — bit-perfect, maximum quality. High bandwidth (~5–10 Mbps for stereo 48 kHz). Best for local LAN use.
Opus — royalty-free, excellent quality at low bitrates (64–320 kbps). Works great over Wi-Fi and remote connections. Supports up to 48 kHz (96 kHz sessions are downsampled).
AAC — Apple's AAC via AudioToolbox. Good quality at moderate bitrates. iOS only.
PCM lossless supports any sample rate your DAW and interface support, including 44.1 kHz, 48 kHz, 88.2 kHz, and 96 kHz.
Opus is capped at 48 kHz by the codec spec. If your session runs at 96 kHz and you select Opus, the plugin downsamples to 48 kHz before encoding. PCM lossless sends the native rate.
Yes. The iOS app can route its output to any AirPlay-compatible device — HomePod, HomePod mini, AirPlay 2 speakers, Apple TV, and third-party AirPlay devices.
Use the audio output picker in the app to switch between your iPhone speaker, headphones, or any available AirPlay destination.
For remote access, you need to self-host the Auxfeed relay server. The relay is a Node.js/TypeScript app — you can run it on any VPS (DigitalOcean, Linode, AWS Lightsail, etc.).
Clone the repo, cd server && npm install && npm start, and enter your relay URL in the plugin and app settings. The relay handles signaling only — no audio passes through it.
See the GitHub README for full setup instructions.
An optional PIN lets you restrict who can connect to your stream. If you set a PIN in the plugin, receivers must enter it to connect.
Leaving the PIN field empty means no PIN is required — anyone on your network (or with relay access) can connect. This is the default and is intentional for easy local studio use.
Check these in order:
1. Same Wi-Fi network. The Mac and iPhone must be on the same network. Check both are connected to the same router/SSID.
2. Plugin is loaded and streaming. The plugin must be instantiated in your DAW session and the stream must be active (signal present).
3. Firewall. macOS firewall may block the plugin's embedded server. Go to System Settings → Network → Firewall → Options and allow the plugin (or your DAW app) to accept incoming connections.
4. Local Network permission. On iOS 14+, the app needs Local Network permission. Go to iOS Settings → Auxfeed and ensure Local Network is enabled.
Yes. The plugin's embedded server supports multiple simultaneous connections. The relay also fans out to N receivers. There's no hard limit — practical limits depend on your network bandwidth and CPU.
