SonoBus

SonoBus is a user-friendly application designed for streaming high-quality, low-latency peer-to-peer audio between devices over the internet or a local network.

To get started, users simply select a unique group name (with optional password) to connect multiple participants for collaborative music-making, remote sessions, podcasts, and more. The software allows for easy audio recording of all participants and seamless playback of audio content to the entire group. Additionally, public groups are available for those seeking to connect with new individuals.

Facilitating connections across the internet, SonoBus enables users to exchange audio within a group while offering precise control over latency, quality, and the overall mix. The application can be utilized on desktops, in Digital Audio Workstations (DAWs), or on mobile devices. Moreover, users can leverage the software within their local area network (LAN) to transmit audio between devices with minimal delay.

SonoBus functions as a standalone application, an AudioUnit v3 plugin with compatible host apps, or through Inter-App Audio. Regardless of the platform used, individuals can establish connections with others using SonoBus seamlessly.

While SonoBus is straightforward to set up and operate, it caters to audio enthusiasts by offering intricate control options. Users can adjust audio quality instantly, ranging from uncompressed PCM to various compressed bitrates through the low-latency Opus codec.

Notably, SonoBus abstains from utilizing echo cancellation or automatic noise reduction mechanisms to preserve the highest audio fidelity. Consequently, when using a live microphone signal, it is imperative to employ headphones to prevent potential echo and feedback issues.

It is worth noting that data communication in SonoBus does not currently incorporate encryption. Although the likelihood of interception is minimal due to its peer-to-peer architecture, users should exercise caution in this regard. All audio content is directly exchanged between peers; the connection server merely facilitates user discovery within a group.

For optimal outcomes and reduced latencies, it is recommended to connect devices via wired Ethernet to the router. Notably, utilizing USB Ethernet interfaces with iOS devices using appropriate adapters ensures uninterrupted functionality. While wireless connectivity is feasible, factors like network jitter and packet loss necessitate larger safety buffers, potentially resulting in higher latencies that may or may not align with specific user requirements.
