Record online meetings with both sides of the call

The participants and you, in one file — no bot joins the meeting

A meeting recording is only useful if it keeps both sides of the conversation: what the others said (the sound your Mac plays) and what you said (your microphone). kilde puts both into one file, works with the meeting app you already use — Zoom, Google Meet, Microsoft Teams, or anything else that plays sound — and never sends a bot into your call.

1. Join the meeting as usual. kilde records your Mac; the meeting service sees no extra participant, because the audio is captured on your Mac, not inside the call.
2. Start kilde with the meeting preset. kilde rec --preset meeting meeting.mov prompts you to pick the meeting window, then records that window while mixing the participants' audio and your microphone into one track. In the menu bar app, choose the meeting window and start.
3. Stop when the meeting ends. Ctrl+C or the stop button — either way the file is always finalized and playable. When a meeting runs long, cap it with --duration 90m.

One window, not the whole desktop. Capture just the meeting window, so your other work stays off the recording. The audio can be scoped to the meeting's app too — sounds from other apps stay out. Recording one app's audio only covers both ways of doing that.

Voices together, or apart. By default both voices land mixed in one track, ready to share. With --audio-tracks separate they are kept apart, which makes later transcription cleaner.

Transcripts, if you want them. On macOS 26 or later, kilde transcribes the recording on your Mac — on-device, nothing uploaded — in Markdown, SRT, WebVTT, plain text or JSON. See transcribing without a bot.

Because it records the microphone only — the participants' voices never reach the file. The short version: kilde captures system audio natively with no virtual audio driver, which is exactly what a meeting needs. Free, open source, MIT-licensed.
