Re: [sc-users] End to end amplitude control and system headroom?

[Philip Galanter <list@xxxxxxxxxxxxxxxxxx>]

Actually I'm normalizing all the sample files as I prepare them,  
although this isn't always as effective as one might hope.  Sometimes  
you get a sort of outlier cycle with a very high value that limits the  
normalization of the overall signal.

Another alternative I've thought of is coding in a compressor to pump  
things up near the end of the signal chain.  Or I could just go Spinal  
Tap, turn it up to 11, and be sure to mind the Dubley.
