MultiTrack - Screen Recorder

MultiTrack records your screen and saves each audio source to its own track within the same file, rather than merging them all into one. When you open the recording in your editor, your voice and the system audio are kept separate—ready for you to work with.

UP TO THREE AUDIO TRACKS

• Microphone — your voice alone, allowing you to edit or mute it later.

• System audio — the sound playing on your device, captured cleanly without your voice overlaid.

• Mix — your microphone and system audio combined, ready for playback without any further editing.

The "mix" is an additional track—it doesn’t replace the others; you can keep all three. You decide the order and adjust the relative volume (weight) of each source within the mix.

THREE FORMATS, EACH FOR A SPECIFIC PURPOSE

• MKV — written in real-time. If a recording is interrupted, the footage captured up to that point remains playable, and MultiTrack automatically repairs the file the next time you open the app. It is the most reliable format and the most convenient for editing.

• MP4 — ready for playback or uploading anywhere. The file is finalized only when you stop recording.

• fMP4 — fragmented MP4: combines the broad compatibility of MP4 with the robustness of MKV.

PRECISE CONTROL OVER QUALITY

• HD, FHD, or your screen’s native resolution.

• 25, 30, 60, or 90 fps.

• Automatic, portrait, or landscape video orientation.

• H.264 or H.265 video codec.

• Bitrate modes: CBR, VBR, or CQ (constant quality).

• Configurable keyframe interval (GOP).

• AAC or Opus audio, with your choice of sample rate, channels, and bitrate.

• Estimated file size per minute, provided before you start recording. TAILORED TO YOUR DEVICE

Every phone supports different resolutions, codecs, and frame rates. MultiTrack checks what your device actually supports and only offers options it can handle, ensuring you don’t choose a configuration that might fail mid-recording.

CONTROLS WITHOUT OPENING THE APP

Pause, resume, and stop playback directly from your notifications. Start recording via the Quick Settings tile or by long-pressing the app icon—with an optional countdown.

NOTHING LEAVES YOUR DEVICE

MultiTrack does not collect data. There are no accounts, no registration, and no servers; your recordings are saved to the "Movies" folder in your device's local storage, accessible only to you. No ads, no watermarks, and no time limits—the only limit is the available storage space on your device. It doesn't even require an internet connection.

REQUIREMENTS

• Android 14 or higher.

• Microphone permission: Required by Android to capture any audio, including system audio. Without it, the recording will be silent.

• Notification permission: Necessary for the pause and stop controls.

• Screen capture authorization: Requested by the system each time you start a recording.

BEFORE YOU INSTALL

• Some apps block the capture of their video or audio content. This is an Android security feature that no recording app can bypass; in such cases, the screen may appear black, or the system audio track may be silent.

• Rotating your device during a recording will result in black bars, as the video resolution is locked at the start. If you intend to record in landscape mode, please set that orientation before you begin.

MultiTrack is currently in open beta. If something doesn't work as expected, please reach out and let me know so I can fix it.
