SonoBus is an easy to use application for streaming high-quality, low-latency peer-to-peer audio between devices over the internet or a local network.
Simply choose a unique group name (with optional password), and instantly connect multiple people together to make music, remote sessions, podcasts, etc. Easily record the audio from everyone, as well as playback any audio content to the whole group.
Connects multiple users together to send and receive audio among all in a group, with fine-grained control over latency, quality and overall mix. Includes optional input compression, noise gate, and EQ effects, along with a master reverb. All settings are dynamic, network statistics are clearly visible.
Works as a standalone application on macOS, Windows, iOS, and Linux, and as an audio plugin (AU, VST) on macOS and Windows. Use it on your desktop or in your DAW, or on your mobile device.
Easy to setup and use, yet still provides all the details that audio nerds want to see. Audio quality can be instantly adjusted from full uncompressed PCM (16, 24, or 32 bit) or with various compressed bitrates (16-256 kbps per channel) using the low-latency Opus codec, and you can do this independently for any of the users you are connected with in a group.
SonoBus does not use any echo cancellation, or automatic noise reduction in order to maintain the highest audio quality. As a result, if you have a live microphone signal you will need to also use headphones to prevent echos and/or feedback.
For best results, and to achieve the lowest latencies, connect your computer with wired ethernet to your router if you can. Although it will work with WiFi, the added network jitter and packet loss will require you to use a bigger safety buffer to maintain a quality audio signal, which results in higher latencies.
SonoBus does NOT currently use any encryption for the data communication, so while it is unlikely that it will be intercepted, please keep that in mind. All audio is sent directly between users peer-to-peer, the connection server is only used so that the users in a group can find each other.
There are binary releases for macOS and Windows available at sonobus.net or in the releases of this repository on GitHub.
For Linux, read the build instructions below.
To build from source on macOS and Windows, all of the dependencies are a part of this GIT repository, including prebuilt Opus libraries.
Open the Xcode project at
Builds/MacOSX/SonoBus.xcodeproj, choose the target you want to build and go for it.
Using Visual Studio 2017, open the solution at
Builds/VisualStudio2017/SonoBus.sln, choose the target you want to build and go for it.
The first thing to do in a terminal is go to the Linux build directory:
Make sure you have
libopus and the
libopus development package (libopus-dev), as well as JACK (jackd) and its development package. Also libasound2-dev , libx11-dev, libxext-dev, libxinerama-dev, libxrandr-dev, libxcursor-dev, libgl-dev, libfreetype6-dev, libcurl4-openssl-dev.
Other distributions may have slightly different package names for these, for instance in Debian, you might substitute libcurl4-gnutls-dev.
If you are using Ubuntu, you can run the following script to install all the prerequisites (scripts for other distributions wanted, please contribute them if you can):
After they are installed, build SonoBus with the following command, both the standalone application and the VST3 plugin will be built:
When it finishes, the executable will be at
Builds/LinuxMakefile/build/SonoBus. You can install it using the installation script.
It defaults to installing in /usr/local, but if you want to install it elsewhere, just specify it as the first argument on the commandline of the script. If you wish to uninstall you can run the uninstall script in the same directory.
License and 3rd Party Software
SonoBus was written by Jesse Chappell, and it is licensed under the GPLv3, the full license text is in the LICENSE file. Some of the dependencies have their own more permissive licenses.
It is built using JUCE 6 (slightly modified on a public fork), and AOO (Audio over OSC), which also uses the Opus codec. I'm using the very handy tool
git-subrepo to include the source code for my forks of those software libraries in this repository.
My github forks of these that are referenced via
git-subrepo in this repository are:
https://github.com/essej/JUCE in the sono6 branch.
https://github.com/essej/aoo.git in the sono branch.
If you want to run your own connection server instead of using the default one at aoo.sonobus.net, you can build the headless aooserver code at
The standalone SonoBus application also provides a connection server internally, which you can connect to on port 10998, or port forward TCP/UDP 10998 from your internet router to the machine you are running it on.
