AudioGraphBuilder.meter() method
The channel-strip meter tap (audio passes through): per channel per window it emits rms_db (the bar), peak_db (the floating peak line) and peak_hold_db (max window peak over the last holdMs, default 1500 ms); with truePeak, also per-channel true_peak_db (BS.1770 4× inter-sample peaks). 10—50 ms windows drive a responsive console meter.
Signature:

name: string;

holdMs?: number;
truePeak?: boolean;
