WaveformNormalization enum

Controls how amplitude values returned by getWaveform / getWaveformBytes are scaled into the 0.0–1.0 range.

Choose perFile for single-track visualizations where you want the waveform to fill the available height regardless of how loud the source is. Choose absolute when you need to compare loudness across multiple tracks — a quiet recording will then visibly look quieter than a loud one.

Values

perFile → const WaveformNormalization

Each waveform is rescaled so its loudest window equals 1.0.

This is the default and matches the behavior of audio_decoder up to and including 0.7.x. Best for showing a single track in isolation: voice memos, podcast previews, chat voice messages, etc.

const WaveformNormalization('perFile')
absolute → const WaveformNormalization

Amplitudes are scaled so absolute loudness is preserved across files.

Two recordings of different loudness will visually differ in height. Best for music apps that show several tracks side by side.

const WaveformNormalization('absolute')
