AudD vs AudioTag

AudD identifies music in audio files, user-generated content, microphone recordings, streams, and video through web, API, and extension access. Results can include artist, title, album, label, release date, and identifiers such as ISRC and UPC; the listed capabilities also include lyrics, listening links, and identification history. AudD says its database contains 160 million songs and uses its own neural-network audio fingerprinting technology. The standard endpoint analyzes up to about 12 seconds per request; longer files require the enterprise endpoint, which can process files of any length and return track timestamps. AudD can monitor radio stations and streams around the clock, returning results through webhooks or long polling. Stream recognition supports Twitch, YouTube, and other stream URLs, with a Twitch extension and embeddable widget. File recognition pay-as-you-go costs $5 a month, billed at $5 per 1,000 requests, and signup includes 300 requests without a credit card. A free plan and trial are listed; stream-monitoring trial inquiries are also available.

AudioTag identifies music from uploaded clips, complete songs, video files, and links to YouTube or other video-sharing services. It returns track, artist, and album details and can separate multiple songs in one recording with their time intervals. Supported formats include WAV, MP3, OGG, FLAC, FLV, AMR, and MP4. Recognition uses proprietary patented acoustic fingerprinting against a music-fingerprint database, matching the same sound rather than merely similar melodies. The homepage reports 47,802,442 tracks, 11,628,927 albums, and 2,450,640 artists. AudioTag is available through a browser and API; the API lets other systems automate recognition. The free service is for non-commercial use. Its free API plan provides up to three hours of audio monthly and requires an account. AudioTag says payment begins only after that allowance is exhausted and the user initiates payment, with no subscriptions.
