Why not screen recording
Audio-only recording keeps the file and workflow lighter
Screen recorders are useful when you need video. But if the task is only to save Chrome tab audio, they add extra steps: record video, export a large file, convert it to audio, then rename it.
Dolphin focuses on the smaller job: record Chrome audio from one tab and save it as a clean local audio file.
Use cases
Built around the task: useful browser audio you want to save
Podcasts and interviews
Capture reference audio from browser players when you have permission to save it.
QA and developer capture
Record website audio behavior for testing, documentation, and reproducible reports.
Web-player audio
Keep useful temporary browser audio without setting up desktop recording software.
Format
MP3 export today, with clear expectations

Best for smaller files, sharing, offline listening, lecture review, and everyday browser audio capture.

Trim the useful part before downloading
After recording, Dolphin shows a waveform so you can keep the part that matters and skip the extra silence at the beginning or end.
Move the trim handles, preview from the new start point, then save the final MP3. It is meant for quick cleanup, not heavy audio production.
Waveform view
Use the visible audio shape to find the right cut point.
Preview after trim
Adjust the segment and hear the kept section before saving.
No separate editor
Avoid downloading a long file just to cut it somewhere else.
Shortcuts
Start and stop recording faster
Use Chrome extension shortcuts when timing matters. Press the shortcut once to start recording the active tab, then press it again to stop.
You can review or change extension shortcuts from Chrome's shortcut settings.
Recommended setup
Chrome extension shortcut
Open chrome://extensions/shortcuts, find Dolphin, then assign a shortcut for starting and stopping recording.

Find the source page again after saving
Dolphin keeps a local recording history with the page title, source URL, duration, filename, and save time. It helps you return to the original lecture, webinar, interview, or web player later.
Source URL
Keep the page link beside the recording so the context does not disappear.
Page title
Use the original page title as a practical memory cue.
Local history
History metadata stays on your device and is not uploaded by the extension.
Faster follow-up
Revisit the source page when you need notes, citations, or the next lesson.
Privacy
Local recording, no audio uploads
Dolphin records and encodes tab audio locally in Chrome. Your recordings are downloaded to your device and are not uploaded by the extension.
The extension uses Chrome permissions for the active tab, tab audio capture, downloads, and an offscreen recording document. It does not capture your microphone.
