You betcha, Ian! Good observation.

Anyway, bottoms up.  Upward compression only, minimal or negligible 
effect on the mid to loud passages. This has been my proposal always! 
And make it optional, list: for noisy locations to make it clear what 
you are doing.

ROBIN, please give me a link so I can change the DNS and we can go live.


Thanks,



Bob
