Re: A bandpass filter, an EQ, maybe even a notch filter.
Thanks for the detailed reply.
You've given me lots of food for thought. I was out last night with my Hearphones and your post had me thinking and listening for sounds that I would want to remove (hi-pass filter), pinpoint and remove (notch filter), or isolate by frequency (bandpass filter).
These are interesting ideas. Thank you for giving me a reason to ponder them.
