Limiting is question of ratio, no? They do high enough ratio, and the non-linear circuit gives acceptably fast response. In my example, I used them as limiters. I can flatline transient rich program material with this sort of THAT based compressor if I really want to, with the non-linear side chain...

An adjustable compressor can be used like a limiter, but not the other way around.

I would not be very optimistic about this... looks like a part to be built inside a cheap digital recorder. The bottom line is that sound quality will be dominated first by the side chain (att/rel/etc) and only secondarily by the gain element. So any one of several options you have chewed on could b...

Anyone know if there is a software Dolby B decoder? The Dolby decoders were typically built into chipsets. You could probably roll your own but I don't recall all the curves... it was a below threshold 1-2 expander mainly operating on HF and limited to only X dB of NR. FWIW I was kind of impressed ...

I still have some Dolby B master tapes but sadly no working Dolby B decoders. Anyone know if there is a software Dolby B decoder? When I was working at Peavey we were a Dolby licensee to manage the NR in the 4 track cassette deck I had to engineer. The Dolby decoders were typically built into chips...

http://www.thatcorp.com/datashts/dn03.pdf Isn't a circuit with four setup trimmers per channel, just on the limiter, a bit impractical for a commercial product or even for customer personalization? It's an application note, not a production schematic. Application notes show you what can be done.......

JR, when you've done Limiters, do you have different TCs for attack & release? Compressor/Limiter (& EQ) design was considered a Black Art at Calrec. Clem, my mike mentor, was considered da man for this. I don't wan't to create too much of a veer but yes... Pure limiters are generally fast ...

The limiter question has not yet been acknowledged as I expected it to be. Limiters do not seem to be such a "hot" question among music recordists, but it's essential on location film recording, because the unexpected always happens. Limiters are widely used for live sound too. THAT does ...

Out with the new and in with the old... I pride myself in being able to fix stuff, but recently my fancy electronic bathroom scale broke. The obvious fault was battery corrosion, the ground wire rotted inside the jacket. It was a slick bio-impedance scale with foot pads to measure/calculate body fat...

I'm using Eagle but an older version. I have to build all my own parts.
