Detecting AI-generated music

Creating a solution for the music industry's biggest problem

In my full time job at Vobile/Pex, I get to work with (ridiculously intelligent) people on all sorts of interesting new music tech. The product I’ve been lasered-focused on lately is our AI music detector API.

The pitch is simple. Give it an audio file, and it’ll tell you whether or not the song was generated by an AI platform like Suno or Udio. The implications of the product are less simple. AI-generated music is swarming platforms like Spotify and YouTube (those background music screensavers are drowning in them) and no one has a great answer of how to systematically differentiate AI songs from human songs. Building a neural network to accurately classify AI-generated songs is a task that gets more and more difficult each passing day.

But we did, and I’m ecstatic with the results we’re seeing. Below is a sample of the blogpost I wrote for my company discussing . It’s a bit sales pitch-y, but it’s also an interesting look into how we’re solving this hard problem. Check it out, and check out the full blogpost here.

From the Pex blog

Every day, thousands upon thousands of AI-generated tracks are flooding streaming platforms, and the numbers are frankly staggering. As of September 2025, Deezer alone is receiving over 30,000 fully AI-generated tracks daily. That’s nearly one-third of all new uploads to their platform. We’re witnessing rapid growth and the music industry is in dire need of solutions.

AI music detection is crucial for protecting copyright while fostering creativity

The International Confederation of Societies of Authors and Composers (CISAC) warned that AI-generated content could put a quarter of musicians’ income at risk by 2028. But the problem runs deeper than just volume. According to Deezer’s internal data, up to 70% of plays on AI-generated tracks appear to be fraudulent. Bad actors are using AI to generate massive quantities of tracks and then artificially inflating play counts to claim royalties that should be going to legitimate artists.

But AI music isn’t all bad, and AI tools democratize music production, allowing more artists to create than ever before. This new, creative genre is also an opportunity for the music industry, which is finding ways to support AI music. In October, ASCAP, BMI, and SOCAN announced they would begin accepting registrations for partially AI-generated musical works, but that works created entirely using AI tools are not eligible for registration. A policy like this requires advanced technology that can distinguish between human-created and fully AI-generated music.

The new Vobile AI Song Detector (powered by Pex) is that technology, and can be used to determine if a song is fully AI generated. Streaming platforms, distributors, and collection societies alike can use the detector to effectively manage AI works.
