After a very brief pass this am, these scripts appear to work just fine! Good work!
I think putting the word scrubber in the title would be the most informative. Actually, would Rubber Scrubber Dubber be too whimsical? 

ha ha ha! That name has it all!  Only thing missing is 3 men in a tub!  

rubber signifies the time stretch function, scrubber indicates the mode of action, dubber indicates the recording function.

thanks! This is great!
