Interesting interview with Bill Cheney of Spectra Sonics in last issue of Tape OP.
I figger audio files do not have these nano peaks. But maybe the conversion process to use outboard gear could add such. ????

LC: My introduction to Spectra Sonics was the 610 compressor. My friend came by with one and told me to turn everything all the way up. It goes crazy.
A normal compressor is a peak-sensing level compressor. Whatever the amplitude of the peak is however much gain reduction you get. In fact, they've taken the definition so far, that anything over 9:1 compression is peak limiting, which is backwards from what we do.
What we do is that the peak is separate from the compression. So we eliminate the peak. The peak limiter in the circuit is in and out of the circuit in 180 nanoseconds [ns]. It's eliminating the peak. So everything else that passes through, there's no peak.
In a peak-limiting mode, you can take our compressor and put it in front of a conventional power amp and get another 10 dB out of that power amp, but not hear it because it's in and out. In the analog world, peaks are bad. Peaks destroy the character of the recorded signal.
LC: It's a fast transient peak that we don't perceive.
Yeah. The peak is gone. There's no musical content; it's purely voltage. So the peak limiter is separate from the compressor. The compressor still attacks at 100 ns, so there is not a transition issue. The compressor ...
