Detect Tampering and Edits in Audio Files
A free audio forensics tool for detecting signs of editing, splicing, or AI generation in recordings. Analyzes audio consistency and patterns to verify authenticity.
How to Use
Upload an audio file
Wait for analysis to complete
Review spectrogram for visual anomalies
Check noise floor and compression results
Read the verdict and confidence score
Detect audio tampering and deepfakes
How is this calculated?
This score combines 4 weighted heuristic checks. It is not a statistical confidence interval and does not replace professional forensic analysis.
score = (1 − raw / 6) × 100, where raw is the sum of weighted checks below:
- Noise-floor inconsistency (RMS coefficient of variation ≥ 0.80) — adds 0.5
- Multi-pass compression (low + high cutoff clusters) — adds 0.5
- ENF discontinuity (50/60 Hz hum drops or spikes) — adds 1.0
- Spectral cuts (flux > mean + 4σ) — adds 0.3 (any) up to ≈2.0 (many)
