# Desktop App v2.0 — System Audio Capture & Offline Mode

> A ground-up rebuild of the Mavio desktop app with improved system audio capture, offline recording, and a redesigned interface.

## Desktop app v2.0

The Mavio desktop app has been rebuilt from the ground up. Version 2.0 is faster, more reliable, and introduces two highly requested features: improved system audio capture and full offline mode.

### System audio capture improvements

Recording system audio is now significantly more reliable across both macOS and Windows.

* **Zero-configuration capture** -- select any audio source from the menu bar without installing virtual audio drivers
* **Per-app audio isolation** -- record audio from a specific application (e.g., only Zoom) while ignoring system sounds and notifications
* **Multi-source mixing** -- capture your microphone and system audio simultaneously with separate volume controls
* **Reduced latency** -- audio capture latency dropped from 200ms to under 50ms

<Note>
  On macOS, system audio capture now uses the native ScreenCaptureKit API (macOS 13+), eliminating the need for third-party audio routing extensions. On Windows, WASAPI loopback capture is used with no additional drivers.
</Note>

### Offline mode

Record and transcribe meetings without an internet connection.

<Steps>
  <Step title="Download offline models">
    Go to **Settings > Offline mode** and click **Download models**. This downloads the speech-to-text and summarization models (\~1.5 GB) for on-device processing.
  </Step>

  <Step title="Record offline">
    When you lose internet connectivity, Mavio automatically switches to offline mode. A yellow indicator shows you are recording locally.
  </Step>

  <Step title="Sync when back online">
    Once connectivity is restored, Mavio uploads recordings to the cloud for enhanced processing. You can also choose to keep recordings local only.
  </Step>
</Steps>

### Redesigned interface

* **New menu bar widget** -- quick access to recording controls, recent meetings, and Mavio AI without opening the full app
* **Dark mode** -- full dark theme that follows your system preference
* **Compact view** -- a minimal floating widget for recording controls that stays out of your way
* **Global hotkeys** -- customizable keyboard shortcuts for start/stop recording, pause, and opening Mavio AI

## Performance improvements

| Metric                   | v1.x   | v2.0   |
| ------------------------ | ------ | ------ |
| App startup time         | 4.2s   | 1.1s   |
| Memory usage (idle)      | 280 MB | 120 MB |
| Memory usage (recording) | 450 MB | 210 MB |
| CPU usage (recording)    | 12%    | 5%     |

## Additional fixes

* Fixed an issue where recordings would occasionally drop the first 3 seconds of audio
* Resolved a memory leak during long recordings (2+ hours)
* Fixed tray icon not updating on macOS Sonoma
* Improved auto-update reliability on Windows -- updates now install silently in the background

<Warning>
  Desktop app v2.0 requires macOS 12+ or Windows 10+. Users on older operating systems should remain on v1.x, which will continue receiving security updates through June 2026.
