Features & Capabilities

Librezam is an open-source browser extension that recognizes music playing in any tab using Shazam’s internal API with optional fallbacks to Audd, ACRCloud, Tencent and NetEase. It supports humming and cover-song recognition (where backends allow), automatic retry across backends, auto-recognition mode, and microphone recording. Results can show customizable streaming providers and include site-specific fixes for services like TikTok and RadioGarden.

Privacy-focused and community-driven, Librezam sends no telemetry unrelated to music recognition and is released under AGPL-3.0 with source on GitHub. Key features include recognition history with CSV export, CORS/Headless/ShadowRoot and AudioBufferSourceNode detection, cross-browser support (Chromium and Android Firefox), keyboard shortcuts, and troubleshooting guidance. This is an unofficial project — contributions and issue reports are welcome.

User Reviews

Librezam is praised for reliable, fast song identification across several platforms and APIs, with a polished UI and open-source design. It can identify tracks by listening to the browser's audio, offering quick results and broad coverage (Shazam, AudD, Google Music recognition, YouTube, SoundCloud). Noted downsides include a minor UX issue in the history view, the need to have the audio tab active, and occasional OS-level setup to enable audio capture.

Pros

Reliable and accurate song identification across multiple platforms.
Very fast results and responsive performance.
Multi-API/multi-platform recognition (Shazam, AudD, Google Music recognition, YouTube, SoundCloud).
Nice UI with an open-source design.
Identifies songs by listening to the browser's audio (on the active tab).

Cons

UX annoyance in the history popup where a small icon near the delete button is hard to click.
Requires being on the tab that is playing audio (not listening across all tabs).
May require OS-level configuration (e.g., enabling Stereo Mix on Windows) to capture audio.

Is Librezam Safe?

Risk impact

Risk impact measures the level of extra permissions an extension has access to. A low risk impact extension cannot do much harms, whereas a high risk impact extension can do a lot of damage like stealing your password, bypassing your security settings, and accessing your personal data. High risk impact extensions are not necessarily malicious. However, if they do turn malicious, they can be very harmful.

Librezam requires some sensitive permissions that could impact your browser and data security. Exercise caution before installing.

Risk impact analysis details

Critical Allows access to all websites, posing a significant security risk as it can monitor and modify data from any visited site.

Risk likelihood

Risk likelihood measures the probability that a Firefox add-on may turn malicious. This is determined by the publisher and the Firefox add-on reputation on Firefox Add-ons Store, the amount of time the Firefox add-on has been around, and other signals about the Firefox add-on. Our algorithms are not perfect, and are subject to change as we discover new ways to detect malicious extensions. We recommend that you always exercise caution when installing a Firefox add-on.

Librezam is probably trust-worthy. Prefer other publishers if available. Exercise caution when installing this add-on.

Risk likelihood analysis details
