Om detta tillägg
This is a browser extension that uses internal API of Shazam to recognize the music playing in the current tab.
Librezam also supports Audd and ACRCloud as alternative backends, which can be changed from the configuration.
Unlike other similar extensions, it works on almost all sites and has fewer bugs.

Requests unrelated to music recognition, such as telemetry, will not be made.
This is unofficial project and is not affiliated or supported by Shazam ltd.

!!Please report extension issues to Github Issue or ‘bqzfjohg@addy.io’, not in the review section, and read the troubleshooting below before reporting the problem !!

Comparison of each backends
  • Shazam
    No registration required, no rate limit
    Privacy-conscious design that sends recorded audio to the server as a fingerprint that cannot be traced back to the original content, rather than sending the audio itself
    Recognition speed is slightly slow
    High recognition rate
  • Audd
    No API key registration required for up to 10 requests per day
    Moderate recognition rate
    Recorded audio is sent to the server as is
  • ACRCloud
    API key registration is required, up to 100 requests per day are free
    Can recognise humming and cover songs
    Very high recognition rate
    Recorded audio is sent to the server as is
  • Tencent
    No registration required, no rate limit
    High recognition rate
    It has a very high recognition rate, especially for anime/game music and Chinese music. For example, this song cannot be recognized by any music recognition service, including Shazam, Audd, ACRCloud, or Google, but only by the Tencent backend.

    High noise and data loss tolerance

===Troubleshooting===
  • Media elements are not detected on some sites, or site-specific issues occur
    In some cases, recording may not start correctly on a very small number of sites due to issues such as audio being played directly by AudioBufferSourceNode, DRM restrictions, or site-specific issues.
    If you encounter site-specific issues, please report the issue and its details on GitHub Issues.
    I also welcome pull requests for fixing issues.
    Please do not report bugs in the review section.

  • Media elements are not detected on all sites
    This may be due to the extension's site permissions being revoked.
    This rarely occurs when updating the add-on.
    Open the permissions tab in the add-on settings and allow permission of ‘Access your data for all websites’
  • Songs are not recognised
    This extension's music recognition processing relies on the Shazam, Audd, and ACRCloud APIs, with Shazam being the default backend.
    If songs are not recognised correctly, try changing the recognition backend or adjusting the recording time in the extension settings.
    ACRCloud has the highest recognition accuracy.
