Quick answer
Record the tab that is playing the audio
A Chrome tab audio recorder captures the sound produced by one browser tab. Open the tab, confirm that its player is audible, start Dolphin on that tab, stop when the useful audio ends, then trim and download the recording as MP3.
This is a focused alternative to screen recording when you need the sound but not the video, microphone, or audio from other desktop applications.
Definition
What is a tab audio recorder?
A tab audio recorder captures sound from a specific browser tab. It is different from a voice recorder, a system audio recorder, and a screen recorder.
Dolphin is made for the moment when you hear useful audio in Chrome and want a clean local file without setting up OBS, QuickTime, Audacity, or a virtual audio route.
Instead of recording your whole screen or desktop sound, Dolphin focuses on the active tab you choose and downloads the result as an MP3 file.
Workflow
How to record audio from a Chrome tab
-
Open the tab with audio
Open the Chrome tab that contains the lecture, webinar, podcast, web player, or website audio you want to capture.
-
Make sure the tab is audible
Play a short sample and check that the Chrome tab and website player are not muted. Dolphin can only capture audio Chrome exposes from that tab.
-
Start Dolphin
Click Dolphin from the Chrome toolbar and start recording the current tab.
-
Keep the source tab stable
Let the audio play normally. Avoid closing, replacing, or reloading the source tab during the recording.
-
Stop and check the waveform
When the useful audio ends, stop recording and confirm that the waveform contains sound before trimming.
-
Download the MP3
Preview the kept segment, trim extra playback from both ends, and save the recording as a local MP3 file.
Capture boundary
Know what a Chrome tab recorder will and will not capture
Choosing the correct recorder starts with the audio source. Dolphin is intentionally limited to the active Chrome tab instead of mixing every sound on your computer.
Not included
Microphone input, room sound, other browser tabs, notifications, or desktop applications.
Not a screen recording
No video, cursor movement, page visuals, or display capture is added to the MP3.
May be unavailable
Some DRM-protected players or streams may not expose audio to Chrome tab capture.
Best fit
When a Chrome tab audio recorder is the right tool
Lectures and courses
Record tab audio from online lessons, language material, training videos, and course players when you have the right to keep a copy.
Webinars and interviews
Save spoken browser audio without creating a large screen recording.
Podcasts and web players

Features
Focused features for Chrome tab audio
Current-tab capture
Record audio from the tab you choose instead of capturing your whole desktop.
Pause, resume, stop
Control the recording when timing matters.
Waveform trim
Keep the important part before downloading.
Smart filenames
Use page title and date hints so recordings are easier to find.
Before recording
Run a short tab audio check before a long session
A ten-second test is faster than repeating a lecture or webinar. Confirm the source and output before the important part begins.
Use the exact source tab
Start the extension while the tab playing the audio is active.
Check both mute controls
Confirm the Chrome tab and the website player are audible.
Record a short sample
Stop, inspect the waveform, and preview the sample before a long capture.
Prepare a filename
Use a topic, source, or date so the downloaded MP3 is easy to identify.
Not a screen recorder
Record the tab audio, not the whole screen
If you only need sound, a screen recorder adds extra work: capture video, export a large file, convert it, and clean up the result.
Dolphin keeps the workflow smaller. It records Chrome tab audio, lets you trim the useful part, and saves a local MP3.
Troubleshooting
If your tab audio recording is silent
Check the active tab
Start recording from the tab that is actually playing audio.
Unmute the tab
A muted tab or silent website player can create a silent recording.
Avoid switching sources
If the site reloads, replaces the player, or opens the media in a new tab, stop and start a fresh recording from the correct tab.
Protected content
Some DRM-based or protected streams may not be available to browser tab capture.
Limits and rights
Use tab recording only when you have permission
A browser recorder does not bypass website access controls, subscriptions, DRM, copyright, or consent requirements. Use Dolphin for your own material, permitted recordings, personal notes, or audio whose owner allows capture.
For live meetings or conversations, follow applicable consent rules. Do not redistribute a recording unless you have the necessary rights.
Keyboard control
A shortcut for moments that start suddenly
Dolphin supports a Chrome extension shortcut so you can start and stop recording without opening the popup first.
On Mac and Windows, open Chrome extension shortcuts and assign the key combination that feels fastest for your workflow.
Recommended setup
Chrome extension shortcut
Open chrome://extensions/shortcuts, find Dolphin, then assign a shortcut for starting and stopping recording.
Mac
Command + Shift + Y
Windows
Ctrl + Shift + Y
Privacy
The audio does not leave your browser
Dolphin processes recordings locally and saves files through Chrome downloads. It does not upload recording audio, page titles, URLs, filenames, or local history.

FAQ
Common questions
How do I record audio from a Chrome tab?
Open the Chrome tab with audio, confirm the tab and website player are audible, start Dolphin from the toolbar, keep the source tab stable, stop when finished, trim the useful segment, and download the MP3 file.
Can Dolphin record only one tab?
Yes. Dolphin is designed to capture the active Chrome tab after you start recording.
Can I save the recording as MP3 or WAV?
Dolphin currently saves recordings as MP3 files. WAV export is not included in the current release.
Does the audio leave my browser?
No. Recordings are processed locally in Chrome and downloaded to your device.
Is Dolphin a screen recorder?
No. Dolphin does not record your screen or create video files. It focuses on audio from the active Chrome tab.
What if the tab is muted?
If the Chrome tab or website player is muted, the recording may be silent. Unmute both controls and make a short test recording before a long session.
Can it record long sessions?
Dolphin is designed for practical browser audio sessions, but very long recordings depend on Chrome, memory, and device performance.
Does it also record microphone or system audio?
No. Dolphin records the active tab audio only. It is not a microphone or full system audio recorder.
Can I record audio from a website with Dolphin?
Yes, when the website audio is playing in the active Chrome tab and is not protected in a way that blocks browser tab capture.
Why did my tab recording stop after the page changed?
Reloading, closing, replacing, or moving the media to another tab can interrupt the original capture source. Start a fresh recording from the tab that now contains the audio.
