Common questions
Can an online screen recorder capture microphone and system audio together?
It can capture microphone audio, and supported browser audio when the browser exposes that option. Chromium tab capture is usually the strongest browser path for including page sound.
Does screen recording record audio?
It can, but the source matters. Microphone narration is the most reliable audio source. Tab or system audio depends on the browser, operating system, and capture mode.
Why is system audio not always available?
Browser audio capture depends on the browser, operating system, and source type. The recorder asks for display audio, but the final option still comes from the browser share dialog.
How do I know whether audio was captured?
Make a short test recording and play it back locally. The player and editor waveform make it easier to see whether speech or sound is present before exporting.
Device selection
The record page shows every microphone the browser can see. Pick your USB mic, headset, or built-in microphone from the dropdown — the selected device is passed directly to getUserMedia.
If your device changes mid-session (e.g., you unplug a headset), the device list updates automatically.
Best browser path for tab audio
For browser audio, start with a Chromium tab recording. If the share dialog shows an audio checkbox for the selected tab, enable it and make a short test clip before recording the final version.
This is more dependable than promising full system audio everywhere. Browser-based recording can ask for audio access, but the share dialog decides what sources are exposed.
Waveform generation
After you stop recording, a WebAssembly module analyzes the audio track and produces waveform amplitude data. This powers the visual waveform in the player and editor timeline — you can see exactly where speech starts and stops.
Audio in the editor
When you open a recording in the timeline editor, audio clips appear on a separate track with the waveform rendered inline. Split, trim, and reorder — the audio stays synchronized with video.
Microphone versus browser audio
Microphone capture is the reliable path for narration. Browser, tab, or system audio depends on the source you choose and what the browser allows in the share dialog.
That is why this page is careful about the promise: the recorder supports audio, but the browser still controls which non-microphone audio sources are available.
