record screen with audio
A silent screen video is rarely enough, whether you're narrating a tutorial or capturing an app's sound. This tool mixes microphone audio and the tab or screen's own audio into a single stream, with independent volume control and a level meter for each source, before you even start recording.
Avoids capturing notification sounds or other apps during narration.
The level meters help avoid the voice getting drowned out by the game, or the other way around.
Always WebM. The browser records natively in that format through MediaRecorder, producing MP4 would require converting the video afterward, a heavy process that either freezes the tab (in a build without origin isolation) or needs resources that would hurt the rest of the site's loading. WebM is open, has excellent quality with the VP9 codec, and plays natively in practically every modern browser and player, including VLC.
Yes, each source has its own gain control (0% to 200%) and its own level meter, adjustable before and during recording.
Recording continues normally without microphone audio, using only system audio if available, or no audio at all if no source is active. No error blocks the video recording because of this.
The screen capture API (getDisplayMedia) or the recording API (MediaRecorder) is not available in this browser or device. Try an up-to-date desktop browser, such as Chrome, Edge, or Firefox.
Everything happens in your browser: screen capture, audio mixing, recording, and trimming. No video, audio, or captured frame is ever sent to any server.
