 ^-- Note: if you get your ears right over time the legacy options still work fine but over time in my experience so far the legacy option helps then you can kick in the Signal Processing Option 'Sample Rate Converter' and keep up on some of the changes going on in your ears. This is a really valuable and powerful option....

Note:
 A previous development ... with 'hamming'. btw ... the hamming right before kaiser_bessel brings out all the percussion out into and through the main part of the coil (and driver). i mean i didnt even read what these functions do but some how the drive through the kaiser_bessel came from hamming right before and everything started to joy ride the phones.... i need to read up on this because i  was confused as to how i was to place these functions ... if i read ill promise in the sense an accomplishment that anyone might be able to accomplish by of course going through the specifics rather though however taking the list by ear each time isnt really a penalty....
