Re: [Audacity-quality] Spectral Selection and Sync-lock - some odd behaviors

[Paul L. <pau...@gm...>]

This is my summary of the behavior:

A track can be selected, or only "sync lock selected" when it is not
selected but at least one track in its sync lock group is selected.

When a track is sync lock selected, pocket watches are drawn in its
background within the time selection.  That applies to label tracks too.

If the clips of an audio track overlap the temporal selection, and the view
is in waveform or wdb, then there are still pocket watches drawn under the
waveform.

But if the clips of a track overlap the temporal selection, and the view is
spectral, then there is no indication of sync lock selection inside the
clip.  That was already true before there was spectral selection, and that
is still true.

If it is a defect that there is no indication of sync lock selection within
the spectrogram, then that is not a new defect special to spectral
selection.

I do not know what would be the good way to draw pocket watches over or
under the spectrogram.  It could be that in the background between clips,
some indication of the spectral selection, not the time selection alone,
could be drawn.  But in the case that the time selection falls completely
within a clip, this would be no help, and spectral selection is not worse
than time-only selection: there is no indication of either.

But the importance of sync lock behavior is not so much what it draws, but
rather how it edits the track.
