Interactive audio app built with Switchboard SDK

Everything you need to build engaging interactive audio

Switchboard handles the real-time audio engine — low-latency processing, live FX chains, multi-party communication — so you can focus on creating experiences that keep users engaged.

Real-time voice communication

Build multi-party voice apps with low-latency audio processing, echo cancellation, and noise suppression baked in.

Live vocal FX chains

Apply real-time effects to voice — pitch shifting, reverb, voice changing — with ultra-low latency on device.

Third-party effect integrations

Plug in professional-grade effects from partners like Voicemod to bring studio-quality tools directly into your app.

Live streaming ready

Integrate with Amazon IVS and other streaming platforms to broadcast interactive audio experiences to a live audience.
