Pex Search
What Pex Search is
Pex Search helps identify music and rightsholders for licensing, compliance, and anti-piracy work. It can check whole audio files against databases, public content, or user uploads, then return results in real time through its SDK. The Vobile Music Registry contains more than 120 million recordings, including catalogs from Sony, Universal, and Warner.
Search can recognize remixes, mashups, nightcore edits, short segments, and multi-track mixes. Its melody-matching technology can also identify covers, live performances, and other uses of compositions that differ from the original recording. Brands can look for music in social media posts during or after upload, or request a custom audit from the Vobile Music Team.
The SDK offers bindings for Python, Go, PHP, and Node.js. Production documentation lists Debian 11 or later, Ubuntu 20.04 or later, and Red Hat 8 or later; ARM-based Mac builds are for development and testing. The product is paid, with pricing available on request. The APIs are in private testing and are not yet publicly available. Pex was founded in 2014 and acquired by Vobile in 2025.
