How it works
Set the highest sample peak to a target without compressing dynamics.
Linked-channel sample-peak normalization. Silent input stays silent. This is not LUFS or RMS loudness normalization.

Example
Target peak(%)=95% : 0.5 → 0.95
Limits
PCM WAV input only:8/16/24/32-bit integer or32-bit float, mono/stereo,8000–96000Hz. Output:16-bit PCM WAV. MP3/M4A/OGG/FLAC are not supported in v1.
Memory is checked from duration, channels and sample rate before decoding. The working budget is64MiB mobile or128MiB desktop; source PCM≤32MiB, duration≤180s.
Sample-peak normalization, not LUFS loudness matching.
