Stereo Tool

I have the Perfect Declipper VST plugin (for use with a
Digital Audio Workstation such as Steinberg WaveLab
or Sony Sound Forge).

If I use Perfect Declipper as an effects plugin with one
of these DAWs, it seems to work without complaint when
rendering audio files at any sample rate supported by the
DAW (up to a limit of 384 kHz, in the case of WaveLab).

My question is -- is Perfect Declipper intended to work
(or work best) at a particular sample rate (44.1 kHz, say),
or is it completely agnostic about this? (I would guess
there might be something like a processing window which
might become smaller with a higher sample rate; also, any
frequency-dependent processing might not function as intended
with a sample rate outside of Perfect Declipper's intended
range of use).

So -- is Perfect Declipper intended to be used only with 44.1 kHz
(or 48 kHz) material, or will it work just as well with
96 kHz, 192 kHz, or even higher?

Thanks.

It will indeed handle anything you throw at it, but the window size (4096 samples) works best at not-too-high sample rates; if you feed it audio at 192 kHz it's actually similar to feeding 48 kHz at 1/4th of the latency (1024) which works less good. The difference isn't huge, but it's there, especially in case of extreme clipping and when there is intermodulation distortion (loud bass causing vibrating mids or highs).
