Can an AI music detector be 100% reliable?
It is the first question people ask: “is it certain?”. The honest answer is no: no AI music detector can be 100% reliable. This is not a flaw of one particular tool, it is the very nature of the problem. Here is why, and how to use a detector wisely all the same.
A never-ending race
A detector learns to recognise the traces left by the generators it has studied. When a new version comes out, these traces change. The detector must then be re-evaluated, sometimes retrained. Meanwhile, its accuracy drops on the most recent tracks. It is the same race as for antivirus software or the detection of generated images.
The two possible errors
- The false positive: a human track classed as AI. This is the most serious error, because it can harm an artist. Our tool is set to limit it, without being able to avoid it completely: in November 2026, out of 545 real tracks it had never heard, 28 were classed “Likely AI” or higher, i.e. 5.1%, about one in twenty. That is why an “AI” score is a clue to check, never proof.
- The false negative: a generated track that passes for human. It is more frequent with recent generators or reworked tracks.
Reducing one of these errors increases the other. Every detector makes a trade-off, and we chose to favour caution.
What blurs the detection
- conversions and recompression (YouTube, social media, low-quality mp3);
- modifications: tempo or pitch changes, re-mastering, added effects;
- hybrid tracks, analysed as a whole;
- styles that are very synthetic by nature (electronic music, robotic vocals).
How to read a score
| Score | What it means |
|---|---|
| below 20% | Nothing suspicious detected. It does not prove a total absence of AI. |
| 20 to 35% | A few weak clues. Do not over-interpret. |
| 35 to 70% | Clear clues. Listen to the flagged passages and look for other evidence. |
| above 70% | High probability of AI generation on the element concerned. |
Good practice
Use a detector as a first filter, never as a judge. Cross-check the result with listening, an investigation into the artist and, if the stakes are high, with proof of creation (session files, separate stems). That is the spirit of our tool: give you clear, located clues, and tell you frankly what it cannot do. The details are on the Reliability page.
