Worked on the livekit/agents-js repository to enhance real-time audio processing by introducing a configurable buffering parameter, queueSizeMs, to the AudioSource component. This feature was implemented using TypeScript and focused on improving the handling of text-to-speech workloads that generate audio faster than real time. By wiring the new parameter through RoomOutputOptions to AudioSource, the solution enabled explicit control over audio buffering, reducing early frame discards and improving playback quality. The work also included a follow-up fix to ensure correct propagation of the parameter across system layers, resulting in smoother audio and a more maintainable configuration surface.

Apr 1, 2026In April 2026, delivered a buffering improvement for the livekit/agents-js audio pipeline by introducing the AudioSource queueSizeMs parameter and wiring it through RoomOutputOptions to AudioSource. This enables explicit buffering control, reducing early frame discards when TTS outputs faster-than-real-time audio and improving audio quality and stability in real-time scenarios. A follow-up fix ensures queueSizeMs propagates correctly across components (commit e399b9b3f51074f749a1946eb0ea5ce7fb03c297, (#1207)). Key outcomes: smoother audio playback for TTS-heavy workloads, fewer buffering-related anomalies, and a more maintainable configuration surface for real-time audio. This work demonstrates JavaScript/TypeScript expertise, audio processing awareness, and cross-layer integration in a live streaming context.
