This is kinda interesting, but it's slightly peverse as some ofthe results
can be got by looking at the source! Though it's good to confirm what the
results actually are.

Like Fons I'm a bit concerned about the tests, 0dB square wave in
particular is worrying.

The point about latency is interesting. I did consider delaying the input
in the SC* plugins, but I guess that analogue compressors likly didn't
have it, and they're often considered to be the best so it can't be too
important.

Have you measureued the systemic delay of the waves compressor to verify
that it does have a delay line?
