Audio Catcher Add to Chrome
Chrome extension · side panel

Every audio file a page loads, listed and ready to export.

A side panel for developers, editors and media teams. Audio Catcher catalogues the audio your browser has already loaded on the page you are working on — preview it by waveform, convert it locally, and export one file or, with Pro, the whole set.

The problem

Collecting audio by hand does not scale.

Auditing what your own site ships, gathering assets you have licensed, checking what a client's page actually delivers — the browser hands you one file at a time, named whatever the CDN felt like.

DevTools is not a workflow

Finding what a page loaded means opening the Network tab, filtering by type, and copying URLs by hand. It works once. It does not work forty times, and it does not work for anyone on your team who does not live in DevTools.

You cannot hear a URL

A column of links tells you nothing about which take is the right one, or which of two files is the full-length master. Without a waveform and a player you end up exporting everything just to listen to it.

Formats never match the pipeline

The page serves AAC or Opus; your editor, your test fixture or your client asked for MP3 or WAV. Converting them one at a time, through a tool that wants an upload, is its own afternoon.

How it works

Three steps, and two of them are just browsing.

Audio Catcher runs in Chrome's side panel, beside the page instead of on top of it. There is nothing to paste and no per-site configuration to maintain.

1

Open the page you are working on

The panel listens while you browse. Playing the audio is enough — you are already doing that while you decide whether the file is the one you need.

2

It catalogues what loaded

Every audio request the page made is listed with its real format, size and duration, plus a waveform you can scrub. The list is built in your browser.

3

Export what you need

One file at a time, or with Pro the whole selection in one ZIP. Export in the standard format (AAC) or convert to MP3 or WAV — audio caught on a regular page is converted in your browser through WebAssembly and never leaves the machine.

Features

A working catalogue, not a download button.

Listing the file is the easy half. The half that saves you an afternoon is being able to find it again, hear it, and hand it over in the format someone else asked for.

Catalogues while you browse

A passive listener recognises 14 audio formats — MP3, WAV, OGG, M4A, AAC, FLAC, WebM, Opus and more — plus HLS and DASH manifests, and keeps up to 1,000 entries.

Listen before you export

Every entry gets a real waveform and an inline player, so you can confirm you have the right take without leaving the panel or opening an editor.

Find it fast

Search by name, filter by type, size or source site, and sort six ways. The list stays usable at a hundred captures.

Export the whole set at once

With Pro, select what you need and one click packages it into a single ZIP instead of thirty separate download prompts.

Convert without uploading

Audio caught on a regular page is converted to MP3 or WAV by ffmpeg compiled to WebAssembly, inside your browser — it is never sent to us. Links from supported social video platforms are the one exception; see the FAQ.

No allowlist to maintain

Any page that plays audio through standard HTML5 or a streaming manifest, including streams split across fragments. Nothing to configure per site.

Keyboard-first

Space↑↓←→FDR — play, volume, track, search, export, remove.

Lives in the side panel

It sits beside the page rather than in a popup that closes the moment you click back into the tab.

Built for professional workflows

The set you need is spread across forty pages.

Audio Catcher keeps everything the session loaded — named, waveformed and searchable — so assembling a set you are entitled to use is one pass through the panel instead of forty round trips through the Network tab.

  • Filter by source site to keep one project's assets separate from another's.
  • Filter by size or format to tell a short preview from a full-length file before you export.
  • Scrub the waveform to confirm the take without opening anything in an editor.
  • Export the selected set with Pro as a single ZIP, converted to the format your pipeline expects.
Acceptable use

What this tool is, and what it is not.

Audio Catcher is a workflow tool for people who already have access to the material they are collecting. It has no way to reach anything your own browser session could not already load, and it does not try to acquire one.

What it is for

  • Auditing and archiving the audio your own site or app ships.
  • Gathering material you own, have licensed, or are otherwise authorised to use.
  • QA and development work against the real media a page delivers.
  • Getting your own uploads and recordings back out of a service.

What it will not do

  • It cannot read DRM-protected streams. Encrypted services never expose a plain file to the browser, and the extension makes no attempt to decrypt one.
  • It does not bypass logins, paywalls or access controls. It only lists what your own session already loaded.
  • It is not a rights-clearing tool. Whether you may keep a file is between you and whoever holds the rights to it.
You are responsible for what you export. Use Audio Catcher only for material you are entitled to save. Accounts used to infringe copyright, to breach a site's terms of service, or to circumvent technical protection measures will be terminated without a refund.
Pricing

Free does the job. Pro removes the ceiling.

Cataloguing, playback, search and single-file export are free and stay free. Pro is for when this is your job and time matters: no wait before each export, MP3 and WAV with no daily cap, and the whole set exported in one pass.

FAQ

The questions worth asking first.

Am I allowed to save the audio I collect?

That depends entirely on the material and on your agreement with whoever owns it, and it is your call to make — not something a browser extension can decide for you. Audio Catcher is built for people working with audio they own, have licensed, or are otherwise authorised to use. It does not grant you any right you did not already have, and using it to infringe copyright or to break a site's terms is a violation of ours.

Does it work on protected or paid streaming services?

No. Services that protect their catalogue with DRM never expose a plain audio file to the browser, so there is nothing for the extension to list. Audio Catcher does not decrypt anything and does not attempt to work around technical protection measures — by design, not by oversight. Any tool claiming otherwise is not being straight with you.

Does it get past logins or paywalls?

No. The extension only works with media your own browser session can already load. If you cannot reach something while signed in as yourself, Audio Catcher cannot reach it either. It does not request the cookies permission, and it never sends your site cookies or passwords to us.

Does it work with video?

Audio is the focus, but not the only thing. When a page loads a video file, the panel lists it in its own tab, and you can save it one file at a time — as MP4 where it needs repackaging — or extract its audio as AAC, MP3 or WAV. The same rules apply: no DRM, no getting past logins or paywalls.

Does my audio get uploaded anywhere?

Not for audio caught on a regular page. Cataloguing reads a request your browser already made, and MP3 and WAV conversion runs on ffmpeg compiled to WebAssembly inside the browser itself.

The one exception is a file you request from a link of a supported social video platform. That link and the file name you chose may be sent to our server, which retrieves the public post, converts it with FFmpeg and hands you a temporary download. The resulting file is deleted automatically about an hour after it is ready. The details are in our Privacy Policy.

Why does it need access to every site?

Because audio can be on any page, and the extension cannot know in advance which one you will be working on. What it does with that access is narrow: it watches for media requests. It does not request the cookies, history, tabs or identity permissions, so it cannot read your browsing history or list your other tabs.

Which formats can I actually get?

It recognises fourteen — MP3, WAV, OGG, M4A, AAC, FLAC, WebM, WMA, Opus, MIDI, AMR, AIFF and ALAC — plus HLS and DASH manifests. For audio output you have three choices: the standard format, AAC (kept as it is when the page already serves AAC), MP3, or WAV.

Which browsers does it run on?

Chrome, and the Chromium browsers that install from the Chrome Web Store and support side panels — Edge and Brave among them. It is not available for Firefox or Safari.

Everything the page loaded, in one place.

Install the extension, open the side panel, and keep working. Single-file export is free, with no account to create.
