SonixClock

The monotonic clock VoxaTrace stamps audio with (ADR-021).

nowNanos is in the same time domain as com.musicmuni.voxatrace.sonix.model.AudioBuffer.timestamp and the wall-nanos argument of audibleTimeMsAtWallNanos — Android CLOCK_MONOTONIC, iOS Mach absolute time converted to nanoseconds. Use it when correlating app-side events with capture timestamps or asking a player for its audible position "now"; platform wall-clock APIs are NOT in this domain.
