pop and click filters

Does anyone know anything about pop and click filters to minimize surface noise on LPs during conversion to tape (cassette)? I know there are sophisticated software/hardware products on the market now that do this and they may well be the only thing that works but I have heard there were once black boxes that minimized noise without losing too much fidelity. Does anyone know of such products and who made them and where can I find one? Thanks

SAE offered the Impulse Noise Reduction System. There are two currently ending soon on EBay, one model 5000 and a 5000A.

Eld, music is filled with trailing AND leading edge transients. For example, an acoustic piano has not only a sustain pedal but a mute one too. Likewise, string players use their palms to mute vibrating strings and resonating wood. These mutes create trailing edge transients, a necessary ingredient in the production and reproduction of music.

Eld, good observation. Like the response to impulse tones some testers seem fond of, I suppose music or any sound created in air necessarily has certain reverb and decay components. Whether recording and playback captures, lessens or enhances those qualities for us back at the ranch makes interesting food for thought.
