Topic: Digicheck showing >25khz Signals on 44.1 Material
My BFP is set to 96Khz and I frequently see signals exciting the 25k, 32k and 40k bands in the Spectral Analyser in Digicheck. Most material is encoded at 44.1, some at 48 and in many cases I am playing back MP3 files.
There should be no signal above 22k espc. with MP3s. Why is the Spectral Analyser showing something in the ultrasonic bands - are these aliasing artefacts?
Playback is via iTunes or Apple Music or whatever they call it these days. Also via the filesystem's quicklook.
