WebAug 16, 2024 · At 22.05kHz, anything above the nyquist frequency of 11.025kHz will be severely attenuated. The cut-off line at ~7.5kHz can't be caused by this unless the file was originally sampled at 15kHz, which is incredibly unlikely. Furthermore the resampling should leave some attenuation above 7.5kHz, so this looks more like a cut-off filter.
