How to use
- Drag a file in, or click the dropzone to choose one.
- Click Analyze. We extract 30-second chunks one at a time and scan every sample for digital clipping. Larger files take longer but stay within browser memory limits.
- Copy the result if you need to share it.
What this checks
A sample clips when its absolute value reaches or exceeds full-scale (1.0 in Float32 PCM, 0 dBFS). We count every clipped sample and report the first ten timestamps so you can locate problem spots.
Verdict: 0–2 clipped samples is pass; 3–100 is warn; above 100 is fail. Lossy decoders (AAC, Opus) routinely round 1–2 samples just above 1.0 on a clean master, so isolated clips on a re-encoded file are normal — we only warn once the count looks deliberate.
