## Phase 77
Select audible bounds finds the first and last sample strictly above the chosen dBFS threshold and pads within the existing selection. It only changes selection; use Trim clip to selection to apply a nondestructive timeline trim, or export the selection. Entirely silent/below-threshold ranges leave selection unchanged. This is boundary detection, not automatic removal of internal gaps or a noise gate.
## Phase 78
Snap to zero crossings searches each selected boundary within a source-frame radius up to 65,536. It uses the mono source, chooses earlier positions on equal distance and changes both endpoints only if both searches yield a nonempty range. Source edges qualify only when their adjacent sample is zero. This can reduce boundary discontinuities but does not guarantee click-free output; musical-tick trimming/slicing can move a boundary away from the exact crossing.
