V07: Main volume and visualizer

Retained analysis
The header visualization toggles between a waveform trace and a frequency plot. The annotation calls the latter a spectrogram, but no time-history axis is shown. Use it for immediate visual feedback, not a saved time-frequency measurement or proof that a transient has disappeared. The master slider is a separate control.
Documentation and visible configuration; not a new native audio test. Project observations are distinct from the source author's claims.
