Vocoded audio in a finished mix
Neural vocoding leaves characteristic behaviour in the upper spectrum — sibilance that is too even, breath noise that repeats a little too exactly, transitions between phonemes that are cleaner than a human larynx manages. In an isolated vocal stem these are often audible to a trained ear.
In a mixed track they largely are not. Once drums, guitars and reverb occupy the same bands, a spectral measurement of the whole file sees the sum, not the voice. That is a genuine ceiling on what this engine can do, and it is why vocal-specific claims are kept out of the report.
What the engine measures instead
The analysis works on the mix. It reads high-band energy distribution, spectral flatness, brightness variability over time and stereo behaviour, and reports how unusual the combination is. When a vocal is very forward and the backing is sparse, those readings carry more of the vocal's character and the result is more informative.
- Sparse, vocal-forward material: the reading is more relevant to the voice.
- Dense, loud production: the reading is dominated by the mix, not the vocal.
- Any bitrate below roughly 192 kbps: the relevant band is largely gone.
Honest limitations
Heavy tuning, formant shifting and modern vocal chains make human voices measurably less human in exactly the bands that matter. A pop vocal through aggressive pitch correction and a de-esser can read like synthesis. We treat vocal-derived evidence as weak by design rather than letting it dominate the score.
ElevenLabs Music detection FAQ
Not reliably from a mixed file. Once the vocal sits inside a full arrangement, the measurements describe the mix rather than the voice. If you have an isolated vocal stem, the reading is considerably more informative.
