03/23/2026, 7:23 AMThanks — you're asking whether silences are removed from LiveKit egress audio recordings.
I don't have a confirmation that silences are automatically removed or trimmed from egress audio recordings. To help you further, could you tell me which of these you mean?
• Are you using LiveKit's built-in egress recording (server-side recording) to produce audio files?
• Are you using a specific egress format or pipeline (e.g., single mixed audio, individual participant tracks, or an external recorder)?
• Do you want silences removed automatically, or are you asking whether there is a setting to enable silence trimming?
With that info I can:
• Confirm whether automatic silence trimming is available for your exact egress method, or
• Suggest alternatives/workarounds (for example, post-processing tools or recording per-participant tracks you can run through a silence-trim step)., with interactive elements

03/23/2026, 7:24 AMThanks — you're using the built‑in egress on LiveKit Cloud and asking whether silences are removed from the audio files it produces.
I cannot confirm that LiveKit Cloud automatically removes or trims silences from egress audio recordings. To make sure I give you the right next steps, could you tell me:
• Which egress format are you using? (mixed single audio file, per-participant tracks, or something else)
• Do you need automatic silence removal during recording, or would a post-processing step after recording be acceptable?
If automatic trimming during egress is required but not available, here are two practical options you can use right away:
• Post-process the recorded file with a tool such as ffmpeg to remove silence segments programmatically.
• Record per-participant tracks (if you aren’t already) and run a silence-detection/trim pass on each track so edits are easier and more accurate.
Tell me your egress format and whether post-processing is acceptable, and I’ll give exact ffmpeg commands or a recommended workflow you can use.
