Mavio offers three recording methods, each suited to different scenarios. You can use them independently or combine them depending on your workflow.

​
Recording methods at a glance

​
How each method works

​
System audio capture

The desktop app captures audio output from your computer using a virtual audio driver. This works with any application — not just meeting platforms. Use it for webinars, podcasts, training videos, or any scenario where audio plays through your speakers or headphones. System audio capture records the mixed output stream. Mavio applies AI-based speaker diarization after recording to identify individual speakers.

​
Browser extension capture

The Chrome extension captures audio from a specific browser tab. When you join a meeting in your browser, click the Mavio icon to start recording. This method captures only the meeting tab audio, ignoring other tabs and system sounds.

​
Mobile recording

The mobile app uses your device microphone to record ambient audio. It is optimized for in-person meetings, interviews, and conferences. The app applies noise reduction and automatic gain control to improve clarity in noisy environments.

​
Audio processing pipeline

Regardless of which recording method you use, all audio follows the same processing pipeline:
1

Capture

Audio is captured using the selected method and encoded as high-quality PCM audio.
2

Upload

The audio stream is uploaded to Mavio’s processing servers over an encrypted TLS connection. With privacy mode enabled, this step is skipped and processing happens on-device.
3

Transcription

The audio is processed by Mavio’s speech-to-text engine, producing a timestamped transcript with 95%+ accuracy across 40+ languages.
4

Speaker identification

AI models identify distinct speakers and label each segment of the transcript. If speakers have been previously identified, Mavio matches them automatically.
5

AI analysis

The transcript is analyzed to generate a summary, extract action items, identify key decisions, and tag topics.

​
Choosing the right method

Join the call in your browser and use the browser extension, or capture it with system audio capture via the desktop app. Both record the call without adding a participant.
Use system audio capture via the desktop app. It works with any application.
Use the browser extension. It captures tab audio silently without adding a participant to the call.
Use mobile recording. Place your phone on the table and the app captures the room audio.
Enable privacy mode in any app. Audio is transcribed and analyzed entirely on your device — nothing leaves your machine.
You can run multiple recording methods simultaneously. For example, use the browser extension for a Zoom web call while also capturing system audio on the desktop app as a backup.

​
Frequently asked questions

It depends on the recording method you are using:
  • System audio capture and browser extension — if you lose connectivity, audio continues to be captured and buffered locally on your device. The recording is queued for upload and will be sent to the server automatically when your connection is restored. No audio is lost.
  • Mobile recording — the app records to local storage regardless of connectivity. The file uploads when your device reconnects.
In all cases, transcription and AI analysis begin after the audio reaches the server. You will receive a notification once processing is complete.
Yes. You can run different recording methods at the same time across devices. For example, you could capture a Zoom call with system audio on your laptop while also running a mobile recording for ambient room audio.Each recording is stored as a separate entry in your meeting library. You can also link related recordings together from the meeting detail page so they appear as a single meeting with multiple audio sources.
Running multiple recordings of the same meeting does consume additional storage against your plan quota. Choose the method that best fits your situation rather than recording everything by default.
Storage depends on the recording quality and duration:Transcripts, summaries, and action items add a negligible amount of storage (typically under 1 MB per meeting). Audio files are the primary storage consumer.You can check your current storage usage in Settings > Data > Storage used and configure auto-delete policies to manage space automatically.
Yes. All recordings are encrypted both in transit and at rest:
  • In transit — audio streams are transmitted over TLS 1.3 encrypted connections between your device and the server.
  • At rest — stored audio files are encrypted using AES-256 encryption in cloud object storage.
  • Privacy mode — when enabled, audio never leaves your device. Transcription and analysis happen entirely on-device using local AI models.
For more details, see the data protection page.
Yes. All recording methods support pause and resume:
  • Desktop app — click the pause button in the menu bar or press Cmd + Shift + P (macOS) / Ctrl + Shift + P (Windows).
  • Mobile app — tap the pause button on the recording screen. The recording resumes seamlessly when you tap again.
  • Browser extension — click the pause icon in the extension popup.
Paused time is not counted toward your recording duration, and silent gaps are automatically removed from the final transcript.
