Screen recording with audio
Lectures, meetings, webinars, tutorials - all the audio, none of the driver hassle.
Most built-in screen recorders either skip audio entirely or only capture the microphone. That is a problem for the things people actually want to record: a 2-hour university lecture, a remote meeting, a webinar, a call where you need both the speaker and your own narration. Screen Recording App captures system sound, microphone, and video together in one step. No download, no account, no virtual audio driver (yes, even on Mac). Works on Windows 10 and 11, macOS, Linux, and ChromeOS.
Need system audio?
Screen Recording App.Internal audio from tabs and apps, captured through the browser's screen picker. No extra driver.
Both sources at once?
Screen Recording App.System audio plus microphone narration in the same recording. One file, both tracks.
Two audio sources, one recording
Screen recordings can include two kinds of audio. Most tools only handle one of them. Screen Recording App handles both.
- Microphone audio is your voice through a headset, webcam mic, or built-in mic. Almost every recorder supports this because the browser can access the microphone directly.
- Internal audio (also called system audio or tab audio) is the sound playing inside an app or browser tab - a video call, a YouTube clip, a game. This is the hard one.
- Why internal audio is hard: operating systems do not expose system sound to recording apps by default. On macOS, you traditionally need a virtual audio driver (Soundflower, BlackHole). On Windows, Xbox Game Bar captures app audio but only for the foreground window. On Linux, it depends on the audio server (PulseAudio or PipeWire).
- How Screen Recording App solves it: Chromium browsers (Chrome, Edge, Brave, Opera) have a built-in audio capture path in their screen-sharing API. When you pick a tab or screen to share, the browser shows an audio toggle. Turn it on, and internal audio flows into the recording alongside your microphone - no driver, no extension, no system config.
Audio recording by operating system
Audio capture support varies by OS. Here is what works where and what you need.
Windows 10 and 11
Internal audio works in Chrome, Edge, Brave, and Opera. Xbox Game Bar captures app audio but only from one foreground window. Snipping Tool has no internal audio at all.
macOS
Internal audio works in Chrome, Edge, Brave, and Opera - no Soundflower or BlackHole needed. The built-in Screenshot toolbar and QuickTime only offer microphone input.
Linux and ChromeOS
Internal audio works in Chromium browsers. On Linux, PipeWire and PulseAudio both support the browser's audio capture path. ChromeOS handles it natively.
Firefox (all platforms)
Firefox supports microphone capture but does not currently offer internal audio through its screen-sharing API. If you need system sound, use a Chromium-based browser.

Internal audio works out of the box in Chromium browsers - no virtual cable, no driver, no routing app. Enable it in the screen picker and the browser does the rest.

Tips for better audio recordings
- For long sessions (lectures, webinars), plug in the laptop. A laptop that sleeps mid-recording is the most common cause of lost audio. Plugged in, brightness allowed to dim, screensaver off - record in peace.
- Use a headset or external microphone. Built-in laptop microphones pick up fan noise, keyboard clicks, and room echo. A basic headset mic improves voice clarity noticeably.
- Close noisy background tabs. If you are recording internal audio from a specific tab, other tabs playing audio will bleed into the recording. Mute or close them first.
- Test before the real recording. Do a 10-second test clip to check that both audio sources are working and the levels are balanced. Easier to fix before a 2-hour session than after.
- Pick the right sharing scope. Sharing a single browser tab captures only that tab's audio. Sharing the entire screen captures audio from all apps. Choose based on what you actually need.
- Use Chrome, Edge, Brave, or Opera for internal audio. Firefox supports microphone only. If system sound matters, switch to a Chromium browser for the recording session.
Frequently asked questions
Common questions about recording audio with a screen recording.
How do I record my screen with audio?
Open Screen Recording App in Chrome, Edge, Brave, or Opera. Enable the microphone in the recorder settings. Click Start Recording and pick what to capture. The browser shows an audio-sharing toggle in the screen picker - turn it on to include system sound. Both audio sources are recorded into the same file.
Can it record a 2-3 hour lecture or webinar with audio?
Yes - that is one of the use cases it was built for. Recordings are saved in small chunks as they run, so a browser crash, a sleeping laptop, or a battery cutting out does not destroy the session. For sessions longer than about 30 minutes, WebM is the recommended format because it finalises faster and is more forgiving than MP4 if anything interrupts the recording. Plug the laptop into power before starting and the rest takes care of itself.
If both microphone and system audio are on, do they overlap or mix?
They mix into a single audio track in the recording. The browser handles the mixing automatically - microphone audio plays alongside system audio at the level each is producing. There is no per-source volume control in the recorder itself (that level of control is where tools like OBS earn their complexity). For a lecture-style recording, this is usually exactly what you want: the speaker plays through the speakers, you narrate over the top, both end up in the file.
What is internal audio and why is it hard to capture?
Internal audio (also called system audio or tab audio) is the sound playing inside your computer - a video call, a game, a YouTube clip. Operating systems do not expose this audio to recording apps by default. On macOS you traditionally need a virtual audio driver. On Windows, Xbox Game Bar only captures one app at a time. Chromium browsers solve this with a built-in audio capture toggle in their screen-sharing flow.
Can I record microphone and system audio at the same time?
Yes. In Chromium browsers, Screen Recording App captures both sources simultaneously. Enable the microphone in the recorder settings and turn on audio sharing in the browser's screen picker. Both streams end up in a single recording file.
Why is there no audio in my recording?
Two common causes. First, the audio toggle in the browser's screen picker was not turned on - it is off by default. Second, Firefox does not support internal audio capture, so recordings made in Firefox will only include the microphone. Switch to Chrome, Edge, Brave, or Opera for system sound.
Does this work on Mac without Soundflower or BlackHole?
Yes. Chromium browsers have their own audio capture path that does not depend on a virtual audio driver. Open Screen Recording App in Chrome, Edge, Brave, or Opera on your Mac, and internal audio works through the browser's screen picker. No kernel extension, no reboot, no system preferences change.
Can I record audio from a specific tab only?
Yes. When the browser asks what to share, pick a single tab instead of the entire screen. The recording will capture only that tab's audio plus your microphone (if enabled). Other tabs and apps are not included.
Do I need to install anything?
No. Screen Recording App runs entirely in your browser. No download, no extension, no admin rights. Open the page, enable audio, and record. The file is saved to your device - nothing is uploaded.
Why does Firefox not support internal audio?
Firefox has not implemented the audio capture option in its screen-sharing API. This is a browser limitation, not a Screen Recording App limitation. Microphone recording works in Firefox, but for system sound you need a Chromium-based browser (Chrome, Edge, Brave, Opera).
