AI Audio Detector — Detect AI-Generated Music & Voice with 12 Analysis Methods
Upload any audio file to analyze whether it was generated by AI tools like Suno, Udio, or ElevenLabs. Our advanced detector examines 12 acoustic heuristics — spectral patterns, MFCC coefficients, onset regularity, dynamics, temporal stability, and stereo characteristics — to estimate the probability of AI origin. Compare two files side-by-side, download PDF reports, and listen to your audio while reviewing results. All processing happens in your browser.

❓ Frequently Asked Questions
How accurate is AI audio detection?
The detector uses 12 independent heuristic methods and combines their weighted results for a probability score. While no method is 100% reliable, our multi-heuristic approach with MFCC, spectral, and temporal analysis provides a strong indication. Accuracy is highest for unmodified AI-generated audio and may decrease if the audio has been post-processed, mixed with real recordings, or heavily edited.
Which AI generators can it detect?
The heuristic analysis can identify patterns common to major AI audio generators including Suno, Udio, ElevenLabs, AIVA, Boomy, Mubert, Riffusion, and similar tools. The detection is based on acoustic properties rather than watermarks, so it works regardless of the specific generator used.
What do the 5 verdict levels mean?
We use a 5-level scale for nuanced results: "Authentic Human Recording" (0-15%) means the audio shows clear signs of natural recording. "Likely Human with Processing" (15-35%) indicates human origin with studio processing. "Uncertain / Hybrid" (35-55%) suggests a mix of AI and human elements. "Likely AI-Generated" (55-78%) shows strong AI indicators. "AI-Generated / Synthetic" (78-100%) indicates high confidence of AI origin.
Can I compare two audio files?
Yes! After analyzing the first file, click "Compare Files" to upload a second audio file. Both results are displayed side-by-side with all 12 indicators, making it easy to compare an original recording with a suspected AI version or to compare outputs from different AI generators.
Can I download the analysis results?
Yes. Click "Download PDF Report" to generate a professional PDF document with all analysis details — final score, verdict, all 12 indicator scores, file information, and disclaimer. Perfect for documentation, content verification, or sharing results.
Does it detect AI voice cloning and deepfakes?
Yes. AI-cloned voices and deepfake audio share many of the same acoustic artifacts as AI-generated music: unnatural MFCC patterns, overly clean noise floors, and suspiciously consistent temporal and spectral characteristics. The detector analyzes these regardless of whether the content is music or speech.
Is my audio file uploaded to a server?
No. All analysis happens entirely in your browser using the Web Audio API. Your audio files never leave your device — nothing is uploaded, stored, or transmitted. This ensures complete privacy for sensitive content.
