To record the sound of a browser tab, open Audio Recorder – Voice Recorder on that tab, choose Tab audio, and press Record. The extension captures the tab through Chrome's tab capture API at 48 kHz and routes the sound back to your speakers, so you keep hearing it while it records.
People often search for an "internal audio recorder" when what they actually need is exactly this: the audio of one web page, clean, without a microphone picking up the room. Tab capture gives you that digital signal directly.
How to record a tab, step by step
- Open the page whose sound you want and make sure it is the active tab.
- Click the extension icon. The status should read Ready.
- Select Tab audio as the source.
- Press Record. After the countdown (3 seconds by default), start playback on the page.
- Watch the waveform. It moves only when the tab is producing sound, which is a quick sanity check.
- Press Stop when you are done. The take appears in the list with its own waveform.
A small tip: start the recording first, then press play on the page. The countdown gives you time, and a second of leading silence is easy to remove with Trim later. Cutting off the first word is not fixable.
No microphone permission is requested for tab-only recording. The mic prompt appears only when the source you choose needs it.
Why you can still hear the tab
When Chrome captures a tab's audio, it normally mutes that tab for the listener. That is fine for a background job and annoying for everything else. The extension plays the captured sound back out to your speakers, so the page sounds the same to you while the recording runs. If you want the technical path — the offscreen document, the capture stream, the routing — it is laid out in How tab audio capture works in Chrome.
Settings that matter for tab audio
Tab audio is a different beast from voice. A few settings deserve a second look before you press Record, because they are locked during a recording:
- Quality: Standard 64 kbps, High 128 kbps (default), Best 192 kbps. Speech from a lecture is fine at High. For music, use Best.
- Channels: Mono is the default. If the tab plays stereo music and you care about the left–right image, switch to Stereo.
- Skip silence: leave it off for tab audio unless the source has long dead gaps you genuinely want removed. It pauses after about 1.5 seconds of near-silence, which can clip quiet passages in music.
- Auto-stop: handy for a stream of known length. Options run from 1 to 180 minutes.
Pages that cannot be captured
Chrome blocks capture on its own internal pages. That includes chrome:// pages and the Chrome Web Store. Try to record one and the popup says: "This tab can't be recorded. Open a regular web page and try again." This is a browser rule, not a setting you can change. See "This tab can't be recorded": what it means for the full list of causes.
Regular websites — a lecture platform, a podcast player, a meeting page in the browser — work normally.
What tab capture does not do
Being precise here saves frustration:
- It records the current tab, not your whole computer. Sound from desktop programs outside Chrome is not part of a tab's audio. The difference is explained in Internal audio vs microphone.
- It records audio only. There is no video track.
- It does not transcribe. You get an audio file, not text.
Exporting the file
Choose a format under Save as and press Download on the take. WebM (Opus) is the default. OGG uses the same Opus codec. WAV is 16-bit PCM, uncompressed and large. MP3 is encoded inside the extension with a bundled encoder, so no extra software is needed. MP3 and Opus bitrates follow your quality setting.
Everything stays in your browser's local storage until you download or share it. There is no upload and no account. The only practical size limit is available disk space.
Recording responsibly
Tab capture makes it technically easy to save whatever a page plays. Whether you should is a separate question. Content on streaming and video sites is often protected by copyright and by the site's terms; personal notes from a lecture you attend are a different situation from re-publishing someone's track. Recording audio from websites responsibly covers the practical lines.
If the tab is a call or a meeting, other people's voices are in the recording. Ask everyone for consent first and follow the recording laws where you and the participants are. Record browser meetings and calls (with consent) walks through it.
One last practical note: if the waveform is flat during a tab recording, check that the page is not muted in its own player and that the tab itself is not muted in Chrome. Nine times out of ten, that is the whole problem.
