Never used RX. That’s bizarre though because there is an Izotope tutorial, albeit a low level one, which explicitly states that it’s amplitude.orthodox wrote: ↑07 May 2021I can't point it on the internet, but it somehow comes from analog signal reconstruction from its sampled values, interpolation of the signal with the condition of limited frequency band, the Nyquist ISI criterion and such.
You can see the perfect illustration in Izotope RX, if you zoom in a (silent) waveform to the samples and try to move one sample.
Is this just an abstract representation? I can see why it would make sense given that the range quoted is unsigned.
