Clipping & Inter-sample Peak Estimator
Scan for estimated inter-sample peaks, hard clipping, and consecutive clipped samples with a visual waveform timeline.
What this tool tells you
What it does
Use this when you want to check a file for hard clipping and estimated inter-sample peaks before or after mastering.
How to use it
Open a file and review the clipped-sample count, maximum consecutive clips, and the estimated inter-sample peak alongside the waveform timeline.
How to interpret it
The inter-sample peak value is an interpolated estimate, not a validated standards-labeled measurement. Even a single hard-clipped sample can be audible depending on context; consecutive clipped samples are the stronger signal of an issue.
Frequently Asked Questions
- What is inter-sample peaking?
- Inter-sample peaks (ISP) occur when reconstructed analog signals between digital samples exceed 0 dBFS. This happens even when no individual sample clips, and can cause distortion in DACs.
- How many clipped samples is too many?
- Even a single clipped sample can be audible depending on context. A few isolated clips may be acceptable, but consecutive clipped samples indicate serious mastering issues.
