Digital Flat-Top Clipping
Detect consecutive hard clipped samples hitting digital ceiling in seconds.
Platform Quality Specifications Reference
| Platform / Standard | Target Loudness | True Peak Ceiling | Technical Notes |
|---|---|---|---|
| Spotify | -14 LUFS | -1.0 dBTP | Normalizes louder tracks down; tracks > -14 LUFS lose perceived dynamics. |
| Apple Music | -16 LUFS | -1.0 dBTP | Sound Check enabled; preserves transient headroom on AAC transcodes. |
| YouTube | -14 LUFS | -1.0 dBTP | Applies rigid peak limiter on non-compliant audio. |
