SonoBus

What it is

SonoBus streams audio between devices over the internet or a local network, with controls for latency, quality, and mix. Participants join by choosing a group name and can add a password. Optional controls include compression, a noise gate, equalization, and master reverb; sessions can also be recorded, and users can play audio content to the group. Supported formats include uncompressed PCM at 16, 24, or 32 bit and compressed Opus at 16–256 kbps per channel. SonoBus is free software for Android, iOS, Linux, macOS, and Windows. It is also available as AU, VST, and AAX plugins on macOS and Windows, and VST3 and LV2 plugins on GNU/Linux. Audio travels peer-to-peer, but data communications are not encrypted. The connection server helps group members find each other, and users can specify their own server; the standalone app can provide connection-server functionality on a local network. The guide describes the app as intended for people who already have a group to share real-time audio. Practical participant counts depend on device, network, and bandwidth conditions. The maker recommends wired Ethernet for lower latency and headphones with a live microphone, since the app does not provide echo cancellation or automatic noise reduction.
