It's supposed to be possible with tabread4~, by using the onset inlet.
There's an example in one of the help files. I looked at it a year ago and
it was incomprehensible. YMMV.

If you figure it out, please post a simple example patch. This is my
greatest joy-killer in Pd, because I really want to work with audio files
which may be 1-2 hrs long.
