I have no idea what McDSP is doing here but taking a quick look in Plugin Doctor shows that it has very different attack/release times for different frequencies. Low and high frequencies have almost instant timings whereas around 300Hz to 2kHz have much longer attack and release constants. Combine this with clever filtering of the control signal and you can pretty much tailor the harmonic series of the compression.DNAudio wrote: Sun Mar 02, 2025 6:10 pm ..but that harmonic suppression sounds interesting to me. Does it just process less at higher frequencies or is it a smarter form of anti-aliasing?
Mind you, this plugin creates zero harmonic distortion unless it is limiting. All of the "mojo" happens when limiting takes place and it's difficult to know if an actual "transformer" algorithm is being crossfaded in by the control signal from the gain reduction or if it's just the harmonics series from the limiter itself that is the shaped and filtered to become the "transformer emulation".
Whatever is done behind the scenes is rather unique and thus I think it may be difficult to copy the exact sound of this plugin with anything else.
