In a minimum phase system phase response and magnitude response are mutually dependent. A near brick wall response filter will necessarily have pretty non-linear phase response which causes pre-echoes.

Date: Monday, January 21, 2013, 5:14 AM another wish of mine is to have a really tight (48db) lowpass filter with minimal effect on the remaining stuff. I'd like to use it for two things: I have some shellac recordings with lots of surface noise and no real signal above 15kHZ and I noticed that my beloved roland drummachines have high frequency stuff in their samples (sampled at double sampling rate), which seem to get problematic since there is real hifi converters.. it would be really nice to have a filter to remove those things without touching the rest.. any recommendations welcome!
