High Quality Network Audio Streaming

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, live sessions, podcasts, etc.

Available for macOS, Windows, iOS and Linux.

Install the software by running 'SonoBus Installer' executable. It will allow you to install the standalone application and the VST2, VST3, and AAX plugins at your discretion.
When you first launch SonoBus, if Windows Gatekeeper prompts you to allow it access to both local and internet networks, give it permission.
Please contact us at if you have any issues.
It is **HIGHLY** recommended that you use an ASIO supported audio driver. You can install ASIO4ALL to enable ASIO for your built-in audio devices or any other that don't have a dedicated ASIO driver. Get ASIO4ALL at

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 very 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.

When using the standalone application, you'll want to setup your audio device first. Press the "gear" button in the top left and select the AUDIO tab. Select your 'Audio device type' first, as mentioned above it is strongly recommended to use ASIO here, and if you do, then select the appropriate device. Otherwise you can use Windows Audio, then select the Input and Output devices you want to use.
You can then select the Input channels and output channels you want to use. If you only have a mono input source (such as a microphone) you can deselect inputs so that only  one is selected, which will reduce the sending network bandwidth.
You can choose a sample rate, 48000 is recommended, but 44100 will also work. The different participants you connect with do NOT need to have the same setting here, audio will be resampled if necessary automatically.
Choose an Audio Buffer Size, this will determine a baseline for the latency, the lower value you choose, the lower the latency, but at a cost of increased processing and network packet overhead. Generally, choosing 256 is safe (when using ASIO), but for lower latency, use 128 samples. You can go lower if your hardware supports it, but it will not be of much benefit unless you use one the PCM send quality options (uncompressed) which can use those smaller buffer sizes.
If you see a yellow bar across the top saying that your audio input is muted to avoid feedback, you can press the button on the top right to Unmute Input. If you are using a microphone input, you will NEED headphones, make sure to connect them before you unmute the input.

Press the Connect... button to get started. Choose a unique group name that you want to use, or use the handy random group name generator (the dice button). You can also enter a password that people connecting to the group will also need to enter for additional security, but it is optional. You can tell others that you want to connect to the group name (and password, if used) or you can press the Copy button in the top right of the Group page, then paste and share it with the other users you want to connect with. They can use it to paste in to this page using the paste button in the top left.
Choose a name for yourself that will be your identifier for anyone else who joins. If someone else is already using that name on the server it will automatically be made unique when you connect.
You can leave the default as the server, or enter another server hostname if you are running your own group connection server. Note that NO AUDIO is sent through the server, it is only used to help the users connect to each other, all audio is sent directly between users (peer-to-peer).
PRESS Connect to Group! If others are already in the group you should see them show up and you'll be able to hear each other. Otherwise, you will see a message indicating that you are waiting for others to join. You can adjust the levels that you hear the others with the volume sliders, or adjust the stereo panning with the Pan button (and popup sliders) for each user.
You can Mute yourself altogether by pressing the microphone button in the lower left corner. When your input is muted you will see a red crossed out microphone. You can also choose who your input is muted for independently, in case you don't want to send audio to certain users, but do to others. You can also mute the output from all or individual users with the speaker button (next to the mic buttons) at the bottom of the window or in each user's area.
