How to Tell If Music Is AI Generated
I spent 3 months analyzing thousands of AI-generated tracks. Here's exactly what to look for — from obvious tells to forensic techniques the pros use. No fluff, just practical methods that work.
AI Music Is Everywhere Now
Last month, a track made entirely with Suno AI hit 2 million streams on Spotify before anyone realized it wasn't human-made. The artist (if you can call them that) had built a following of 50,000 fans who genuinely thought they were listening to an emerging indie band.
This isn't an edge case anymore. In 2025, platforms like Suno, Udio, and Boomy are generating over 100,000 tracks per day. Some are obvious garbage. Others are indistinguishable from human production — until you know what to look for.
Whether you're a label exec checking submissions, a journalist verifying sources, or just a curious listener, knowing how to spot AI music isn't optional anymore. It's a necessary skill.
Train Your Ears: The 5 Audio Tells
Before you reach for any software, start here. Your ears can pick up patterns that algorithms miss — if you know what to listen for. These are the five audio artifacts I've found most consistent across AI-generated tracks.
The "Vocal Glue" Effect
AI vocals often sound slightly smeared, like someone blended multiple takes together. Listen for words that bleed into each other unnaturally, especially on plosives (p, b, t sounds). Real human vocals have micro-variations in breath and attack that AI smooths over.
Repetitive Drum Patterns
Current AI models struggle with drum variation. They'll loop the same 4-bar pattern for an entire track. Human drummers instinctively add fills, ghost notes, and timing variations. AI keeps it safe and repetitive.
The "8-Bar Loop" Structure
Most AI music generators default to 8-bar loops. You'll hear the same chord progression, melody, or drum pattern repeating with minor variations. Human songwriters build tension and release; AI builds loops and variations.
Frequency Gaps in the Mix
AI-generated audio often has weird spectral gaps — frequencies that should be present but aren't. Listen on good headphones for a "hollow" quality, especially in the 5-8kHz range where vocal presence lives.
Impossible Arrangements
AI doesn't understand physical instruments. You'll hear "guitars" playing chords no human hand could reach, or drums with impossible stereo imaging. These are dead giveaways if you know what real instruments sound like.
Spectral Fingerprinting (Free Tools)
When your ears aren't enough, look at the audio visually. AI leaves traces in the frequency spectrum that are invisible to listeners but obvious in a spectrogram. Here's how to check for free.
Download Audacity (Free)
Audacity is open-source audio software that shows spectrograms. Import your suspicious track and switch to Spectrogram view (Track → Spectrogram).
Look for "Grid Lines"
AI audio often shows unnaturally regular patterns — horizontal lines at specific frequencies that stay constant. Human audio has organic variation. AI looks mechanical.
Check the 8-12kHz Range
Suno v3 and v4 leave distinct artifacts between 8-12kHz. Look for bright horizontal streaks in this range that don't correspond to obvious musical content. Udio leaves traces at 5-15kHz.
Compare to Known AI Tracks
Download a confirmed Suno or Udio track from YouTube. Compare its spectrogram side-by-side with your suspicious track. Similar patterns mean similar origins.
Save spectrograms of confirmed AI tracks as reference. I keep a folder of "fingerprints" from Suno v3, Suno v4, Udio Beta, and Boomy. When I analyze a new track, I can spot the source platform in under 30 seconds by visual comparison.
Metadata Deep Dive
Every audio file carries hidden data. Sometimes that data tells you exactly where the file came from — or reveals that someone tried to hide its origin.
Reverse Search the Audio
AI-generated tracks often appear in multiple places online. A quick search can reveal if the "original artist" is actually distributing the same track under different names across platforms.
YouTube Content ID
Upload the track (privately) to YouTube. If it's AI-generated from a major platform, Content ID may flag it. Even if it doesn't, check the "Music in this video" section for matches.
AcoustID / Chromaprint
Use AcoustID to generate an audio fingerprint. Search their database for matches. AI tracks sometimes match multiple "different" songs — a dead giveaway.
Shazam / SoundHound
Try identifying the track with Shazam. If it matches something completely different, you might have a copy or derivative. If it matches nothing despite being "polished," that's also suspicious.
Use an AI Music Detector
Sometimes you just want a definitive answer. AI detection tools analyze spectral patterns, frequency distributions, and acoustic fingerprints to determine if audio is machine-generated. Here's how they work.
How AI Detection Actually Works
Spectral Analysis
The detector converts your audio into a spectrogram and analyzes frequency patterns.
Model Comparison
It compares your track against databases of known AI-generated signatures.
Confidence Score
You get a probability score plus detailed breakdown of why it flagged the track.

Know Your AI Platforms
Each AI music generator has distinct characteristics. Once you learn the signatures, you can identify the source platform just by listening.
Suno
Most Popular- Vocals have a distinctive "polished" quality
- Chorus sections often repeat verbatim
- Tracks rarely exceed 4 minutes
- High-frequency artifacts at 8-12kHz
- Often lacks a proper bridge section
Udio
Long Form- Can generate up to 15-minute tracks
- More varied song structures than Suno
- Better at extended instrumental sections
- Artifacts in 5-15kHz range
- Multi-language vocals sound more natural
Boomy
Instrumental- Primarily instrumental tracks
- Lo-fi and ambient genres dominate
- Simpler arrangements than Suno/Udio
- Repetitive melodic loops
- Less polished mastering
When You Need Proof
Sometimes the stakes are high enough that you need bulletproof evidence. Legal disputes, copyright claims, or professional journalism require more than educated guesses. Here's how the pros do it.
The 2-Minute AI Detection Checklist
3+ checks positive: Very likely AI-generated
1-2 checks positive: Suspicious, needs deeper analysis
0 checks positive: Probably human-made
Common Questions About AI Music Detection
Can AI-generated music be detected 100% accurately?
No detection method is 100% accurate. The best forensic tools achieve 95%+ accuracy on known AI platforms, but new models and post-processing techniques can fool detectors. Use multiple methods for the most reliable results.
Does mastering or editing hide AI fingerprints?
Basic editing (EQ, compression, reverb) rarely removes AI signatures completely. Heavy processing like time-stretching, pitch-shifting, or aggressive noise reduction can reduce detection confidence but usually leaves traces that forensic analysis can still identify.
What's the difference between Suno and Udio detection?
Suno leaves high-frequency artifacts (8-12kHz) and tends toward shorter, more repetitive structures. Udio produces longer tracks with artifacts in the 5-15kHz range and more varied arrangements. Our Suno detector and Udio detector are tuned for these differences.
Can Spotify and Apple Music detect AI music?
Streaming platforms are developing detection systems, but their methods aren't public. Some labels use third-party detection services before distributing. Currently, most AI tracks slip through unless they're explicitly flagged by users or rights holders.
Is it illegal to release AI-generated music without disclosure?
Legal requirements vary by jurisdiction and platform. Some distribution services now require AI disclosure. In the US, the Copyright Office has ruled that purely AI-generated works lack human authorship and can't be copyrighted — but they can still be distributed. Always check your platform's terms of service.
How do I prove a track is AI-generated in a dispute?
Document everything: run the track through multiple detectors, save spectrograms, capture metadata, and get a timestamped report. For legal proceedings, use a certified forensic audio lab. Screenshots of detection results are better than nothing, but chain-of-custody documentation is essential for court.
