AudioTag

What AudioTag is

AudioTag identifies music in uploaded audio fragments or full songs and returns track, artist, and album information. It can also process links from YouTube and other video-sharing services, and supports formats including WAV, MP3, OGG, FLAC, FLV, AMR, and MP4. Audio within video files can be recognized, and a recording with several songs can be split into identified tracks with their time intervals. AudioTag uses proprietary, patented acoustic fingerprinting and a database of music fingerprints. Its homepage reports 47,802,442 tracks, 11,628,927 albums, and 2,450,640 artists. The method matches the same sound; it does not find music that is only melodically similar. AudioTag is available on the web and through an API for automating recognition in third-party systems and applications. The free service is for non-commercial use. The Free API plan provides up to three hours of recognition audio each month and requires an account. AudioTag says it has no API subscriptions: payment is initiated only after the monthly free audio budget is used.

Who it suits

AudioTag suits listeners identifying recorded music and developers adding music recognition to another system. The free service is limited to non-commercial use, while the API plan has a monthly audio allowance.

Limits

The free service is for non-commercial use. The free API plan covers up to three hours of audio per month and requires an account; charges may begin after that allowance when the user initiates payment.

Getting started

1. Open the AudioTag website in a browser.
2. Upload an audio fragment or full song, or provide a supported video-sharing link.
3. For API use, create an account to access the free monthly allowance.
4. Use up to three hours of audio per month on the free API plan.

Verdict

AudioTag offers web and API recognition, including support for multiple tracks in one recording. Its fingerprinting matches the same sound rather than melodic similarity, so that distinction matters when choosing it.
