As a moderator on a friendly group, may I ask John if he would consider adding Amplitude sweeps.

Plotting compressor curves on PC

I'm trying to find a way to measure and plot compressor/limiter curves on a PC. This would involve amplitude sweeps and input / output plots I use the excellent REW for eq frequency plots but can't find a way to plot amplitude other than painstakingly writing it all down and putting the data...

The stepped sine measurement can do that, albeit a little slowly. If you run a stepped sine THD vs level test the the SPL & Phase graph for the result shows output level vs input level, there is also a linearity plot which shows the deviation from a linear response although that is normalised to the maximum input so not ideal for a compressor.

How can I set this up? Can't find it in the Help.

The link in my post goes directly to the stepped sine help. It's on the RTA.

Thanks! Didn't see the link. Doh!
