A great way to instantaneously peak limit is to overload a non feedback tube or transistor amplifier.
This could further be improved by including pre and post emphasis. For example increasing high frequency content then overloading and then reducing high frequency content as used in FM broadcasting.
This has the advantage of rounding edges!. it has also been used in tube guitar amplifiers driving the low pass speaker. Mike Oldfield conceived an ingenious technique of clipping a guitar on a tape recorder mic input then eqing to increase treble then overloading then eqing to decrease treble or something of that sort (more on a transcribed interview of Mike Oldfield on the web).
Tape recorders use the same amazing principle of low cut (head is constant current driven by a high Z amplifier, this gives 6bd per octave drop as in a Pleiades filter). Then the tape can be softly saturated ,the differentiated signal is the integrated (high cut), magic!.Most of the greatest sounding music recordings on our planet use this technique to advantage. Same with vinyl, pre post emphasis, RIAA.
It would be great to make a tape recorder with no tape. This could be done by using 2 heads facing each other and take to advantage pre post emphasis. Or use a Pleiades transformer wound on a Magnetec or noncrystalline core or other core to use B-H magnetic saturation curves for instantaneous peak limiting with the high cut needed to restore flat response and consequently rounding the instantaneously peak limited signal.
