MultiTrack - Screen Recorder

MultiTrack records your screen and saves each audio source to its own track within the same file, instead of merging them into one. When you open the recording in your editor, your voice and system audio arrive separately and ready to work with.

UP TO THREE AUDIO TRACKS
• Microphone — your voice alone, for editing or muting later.

• System Audio — what's playing on the device, clean and without your voice overlay.

• Mix — microphone and system audio together, ready to play back without any editing.

The mix is ​​an extra track; it doesn't replace the others. You can use all three at once. You decide the order and adjust the weight of each source within the mix.

THREE FORMATS, EACH FOR A SPECIFIC USE
• MKV — written on the fly. If the recording is interrupted, what was recorded up to that point remains playable. The safest and most convenient for editing.

• MP4 — playable and uploadable anywhere. It ends when you stop.

• fMP4 — MP4 by fragments: MP4 compatibility with the durability of MKV.

REAL CONTROL OVER QUALITY
• HD, FHD, or your screen's native resolution.

• 25, 30, 60, or 90 fps.

• H.264 or H.265 video codec.

• CBR, VBR, or CQ (constant quality) bitrate mode.

• Configurable keyframe interval (GOP).

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

• Estimated bitrate per minute before recording begins.

TUNED TO YOUR DEVICE
Every phone supports different resolutions, codecs, and bitrates. MultiTrack checks what your device actually supports and only offers what it can handle, so you don't choose a setting that will crash mid-recording.

CONTROLS IN THE NOTIFICATION
Pause, resume, and stop directly from the notification, without returning to the app.

NOTHING LEAVES YOUR DEVICE
MultiTrack doesn't collect any data. There are no accounts, no logs, and no servers: recordings are saved in the Movies folder of your own storage, and only you have access to them. No watermark and no time limit—the only limit is your available storage space.

WHAT YOU NEED
• Android 14 or higher.

• Microphone permission: Android requires this to capture any audio, including system audio. Without it, the recording will be muted.

• Notification permission: This is where the pause and stop controls are located.

• Screenshot authorization, which the system requests for each recording.

BEFORE INSTALLING
• Some apps block the capture of their image or audio. This is an Android security feature that no recording app can bypass: in these cases, the screen may go black, or the system audio track may be muted.

• Rotating the device mid-recording leaves black bars. The resolution of a video track is fixed at the start and cannot be changed on the fly.

MultiTrack is in open beta. If something isn't working as expected, let me know and I'll fix it.
