the workaround i have at the moment is that audacity lets you export cue points as a .txt file.

As long as you don't add any labels to your cue points, then that text file contains a list of cue point times which you can read directly into an array in pd. 

in audacity, do the following:

Project -> New Label Track
select your cue points (Add Label at Selection)
File -> Export Labels






however, a pd object to read the cue points from .wav or .aiff files would be very useful.  from what i have been reading, all the cue points are stored as a single line of data in the header of the file.


here's a cue point reader as a supercollider patch:
