What AudD is

AudD identifies music in audio files, user-generated content, microphone recordings, streams, and video. It is available through a web interface, an API, and an extension. AudD says its catalog contains 160 million songs and uses its own neural-network audio fingerprinting technology. Results can include artist, title, album, label, release date, and identifiers such as ISRC and UPC; lyrics, listening links, and identification history are also listed. For continuous monitoring, AudD can watch radio stations and audio streams around the clock and return matches through webhooks or long polling. It can recognize music from Twitch, YouTube, and other stream URLs, and offers a Twitch extension and embeddable widget. The standard endpoint analyzes up to about 12 seconds per request, while the enterprise endpoint handles files of any length and returns recognized tracks with timestamps. AudD lists SDKs for Python, Node.js/TypeScript, Go, Rust, PHP, Swift, Kotlin, C#/.NET, Java, C, and C++, as well as an MCP server for AI agents. Signup includes 300 recognition requests without a credit card. File recognition pay-as-you-go costs $5 a month, billed at $5 per 1,000 requests. Stream recognition plans cost $25 a month for uploaded music or $45 a month for AudD’s catalog, each billed per stream. A volume plan costs $1,800 a month for 500,000 requests.
