What did Deezer’s AI music detection tool reveal?
Paris, January 24, 2025 – Deezer, the global music experiences platform, has deployed an AI music detection tool that identified approximately 10,000 fully AI-generated tracks delivered to the platform each day. These tracks represented around 10% of Deezer’s daily content delivery in January 2025.
The technology had been in development for approximately one year. Deezer designed the tool to detect fully AI-generated music across multiple generative models and to identify synthetic content without relying exclusively on large, model-specific training datasets.
The company also filed two patent applications in December 2024. The applications cover different methods for identifying the signatures that distinguish synthetic audio from authentic recordings.
Why is Deezer developing an AI music detection tool?
“As artificial intelligence continues to increasingly disrupt the music ecosystem, with a growing amount of AI content flooding streaming platforms like Deezer, we are proud to have developed a cutting-edge tool that will increase transparency for creators and fans alike,” said Alexis Lanternier, CEO, Deezer. “Generative AI has the potential to positively impact music creation and consumption, but its use must be guided by responsibility and care in order to safeguard the rights and revenues of artists and songwriters. Going forward we aim to develop a tagging system for fully AI generated content, and exclude it from algorithmic and editorial recommendation.“
Deezer’s launch objective was to make fully AI-generated music visible to listeners while protecting the discovery systems that help human artists reach audiences. The planned tagging system would give users clearer information about what they were hearing and would allow Deezer to distinguish fully synthetic music from music created through a broader human process.
The detection initiative also addressed the growing volume of synthetic audio delivered to streaming platforms. AI tools make it possible to create large quantities of music quickly, increasing the risk of catalog dilution, fraudulent streams, and reduced visibility for artists who rely on organic discovery.
How does Deezer detect fully AI-generated music?
The tool detects artificially created music from generative models such as Suno and Udio. Deezer can add detection capabilities for other similar tools when relevant data examples are available.
The system identifies specific artifacts and signatures created during the generation process. These signals are generally inaudible to people but can be identified by software. Because different generative models can leave different signatures, the technology can also help identify the model used to create a track.
Deezer has also developed a more generalizable approach that does not require a separate dataset for every model. This capability is important because generative AI models evolve quickly and detection tools must adapt to new systems and new forms of synthetic audio.
“We set out to create the best AI detection tool on the market, and we have made incredible progress in just one year,” said Aurelien Herault, Chief Innovation Officer, Deezer. “Tools that are on the market today can be highly effective as long as they are trained on data sets from a specific generative AI model, but the detection rate drastically decreases as soon as the tool is subjected to a new model or new data. We have addressed this challenge and created a tool that is significantly more robust and applicable to multiple models.”
What will Deezer’s AI tagging system change?
Deezer planned to tag fully AI-generated content and remove it from algorithmic and editorial recommendations. This approach would preserve listener choice while preventing synthetic tracks from receiving the same discovery opportunities as music selected for Deezer’s recommendation systems.
The tagging system would focus on music that is 100% generated through generative AI platforms. Music that includes selected AI-assisted elements within a wider human creative process is different from fully AI-generated music and requires separate evaluation.
The launch also established the basis for Deezer’s later tagging system, which was introduced in June 2025. The system applies the visible label at album level to reduce the risk of false positives and to make it more difficult for bad actors to reverse engineer detection signals.
How is Deezer preparing for synthetic voices and deepfakes?
Deezer planned to extend the technology to detect deepfake voices and other forms of synthetic audio. Voice cloning creates additional risks for artists because it can imitate a performer’s identity and create recordings without the artist’s authorization.
Detection technology gives platforms a way to identify synthetic media before it affects recommendations, charts, royalty calculations, or audience trust. It also creates a foundation for clearer information about the origin of recorded music.
Why does AI detection matter to artists and creators?
Deezer’s AI detection work formed part of its broader commitment to fairness and transparency in the music ecosystem. In October 2024, Deezer became the first and only streaming platform to sign the global statement on AI training, taking a position against the unlicensed use of creative works to train generative AI systems.
The economic stakes are significant. According to a study conducted by CISAC and PMP Strategy, with participation from key industry players including Deezer, nearly 25% of creators’ revenues are at risk by 2028. The potential impact could reach €4 billion. Read the AI music study.
Deezer’s approach is based on transparency, responsible technology, and protection for artists and songwriters. The company’s detection system is designed to help listeners understand what they are hearing while reducing opportunities for synthetic content to dilute music catalogs or divert royalties.
What happened after the 2025 launch?
Deezer introduced explicit AI-music tagging in June 2025 and continued to exclude detected fully AI-generated tracks from algorithmic recommendations and editorial playlists. The company later made its detection technology commercially available to other organizations in the music ecosystem, including rights organizations, distributors, and streaming services.

Notes to editors
Deezer’s AI music detection tool sets an industry standard, with the ability to detect 100 % AI-generated music from the most prolific generative models – such as Suno and Udio, with the possibility to add detection capabilities for practically any other similar tool as long as there’s access to relevant data examples. Not only that, Deezer has made significant progress in creating a system with increased generalizability, to detect AI generated content without a specific dataset to train on. The reported increase comes at a time of growing concerns about AI companies training their models with copyrighted material, and governments potentially diminishing copyright laws to facilitate AI development. Deezer is committed to protecting the rights of artists and creators, and remains the only streaming platform to sign the global statement on AI training.
AI is a critical challenge for the music industry – According to a study conducted by CISAC and PMP Strategy, with participation from key industry players, including Deezer, nearly 25% of creators’ revenues are at risk by 2028, which could amount to as much as €4 billion by that time. This represents a colossal, even critical, challenge for the music creation sector as a whole. Read the CISAC and PMP Strategy study.
Delivery vs streams – Most of the daily delivery of AI tracks are never streamed on Deezer, but they are diluting the catalog and are used for fraudulent activity – today, up to 70% of all streams of fully AI generated tracks are fraudulent.
Two new patents – In December 2024, Deezer applied for two patents for its AI Detection technology, focused on two different methods of detecting unique signatures that are used to distinguish synthetic content from authentic content.
