Record Microsoft Teams calls on a Mac.

Desktop app or browser, the same two tracks

echo99 never joins the Teams meeting and never appears in the roster. It records your Mac instead, so it works the same with the Teams desktop app or Teams in a browser:

• Your microphone, saved as mic.wav and labeled “Me”.
• Everything Teams plays, saved separately as system.wav. On-device speaker separation (diarization) labels the other voices “Them-1”, “Them-2”, …

Transcription runs on your Mac after the meeting, and the audio never leaves it. echo99 records sound only, not video or shared screens.

How to record a Teams meeting

1. Do echo99’s one-time setup with getting started: two permissions (microphone and system audio recording) and the on-device models.
2. Join with computer audio rather than dialing in from a phone, because phone audio never passes through your Mac. echo99 records the Mac’s default input (System Settings → Sound → Input), so select the same microphone in Teams’ device settings.
3. Click Record in the echo99 menu-bar panel.
4. Click Stop Recording after the meeting. Open Recordings to listen back and read the transcript once it’s processed.

Recordings are saved in ~/Documents/echo99/, one folder per meeting named by its start time; Config → Storage changes the location. Run a short test first. If either side stays silent for about 90 seconds while the other has sound, the menu-bar panel says “Mic looks silent” or “System audio looks silent”. Wearing headphones keeps the other voices out of your mic track; with speakers, Config → Transcription → Speaker echo removes the echo from your transcript.

If you’d rather not start it by hand, turn on Auto-record calls in the menu-bar panel: echo99 starts a few seconds after Teams opens your microphone and stops shortly after the meeting releases it. In a meeting where you only listen and no app is using the mic, start recording yourself.

Teams recording, intelligent recap, and a local copy

In work and school accounts, Teams recording is controlled by your organization: an admin policy decides who may record, and the file goes to the organizer’s OneDrive (or the channel’s SharePoint site) under the organization’s retention rules. Intelligent recap, the AI notes built from the meeting transcript, needs a Teams Premium or Microsoft Copilot license. In Teams for personal use, recording needs a Microsoft 365 Personal, Family, or Premium subscription, and the recording is kept in the cloud for 30 days.

echo99 keeps a private copy on your Mac instead: your own audio and transcript, whatever license the meeting runs on, plus an optional summary from a local model. It complements Teams’ recording and does not change what your workplace permits, so check those rules before you record.

Tell people you are recording

echo99 never joins the Teams meeting, so nothing like Teams' recording banner tells the others you are recording. Many jurisdictions require the other side’s consent, and your organization or the host may have rules of its own. Say it out loud at the start, before the conversation gets going.

Teams’ recording policies, licenses, and storage behavior change; the notes above were last reviewed October 2026. See Microsoft’s documentation on Teams recording policies, where recordings are stored, recap in Teams, and recording in Teams for personal use for current details.
