The idea is to move an audio-track to a specific start position and be
able to re-align it repeatedly. the use-case to synchronize sound-tracks
or recordings. it would be nice to have a simple method to re-align
chunks of audio to some initial (or default) timecode as well.
Maybe this is already possible, and I'm not aware of it - that's why I
asked before making a feature-request ;) - thanks for the quick reply.

the region-editor in ardour2 misses an option to specify an offset where
to start in the audio-clip. - maybe I'm missing something on how to
cut/edit chunks by numbers with ardour.

audio-chunks that have been cut from a region should /inherit/ the
region's timecode. - maybe they already do? how can I make use of it?
Sometimes I end up dragging regions and moving chunks around and it'd be
nice to restore their initial position or duration.
A popup-dialog or menu could allow to select different modes:
- cut a region from the original source for this absolute position
- reposition this chunk of audio so that it's timecode matches
the timecode (or offset) from the souce file. - optionally retain the
absolute start or end position of the chunk.
maybe the latter is enough, the former can already be achieved with a
few extra clicks and the region-editor.
now that I think of it: it may be possible with a few marks, and cursor
jumps and "align-relative".. but this is just brainstorm.

Is it called "nudge-by-capture-offset" ?

The ardour session could /fake/ BWF headers for file-formats which don't
support it, and allow to edit/override the information. yes it's a bit
dubious. Are there any standalone BWF header editors/generators around?
- will ardour re-load the header-information on restart or would that
need to be done before importing the audio?
