[RTTY] Audio filters

[K4SB]

I'm wondering how many of you guys use in line audio filtering? And if
so what type unit.

Can't seem to find one on the internet..maybe because I don't know the
right "key word".

And yes the OMNI VI+ has more than adequate DSP and Noise reduction
filters already installed. As well as CW filters down to 250 cycles. 

What I want is is a filter which would go in line with the P38 or the
output of the rig to the sound card.
