Not to mention audible if it's severe enough. Decimation filters
that only give 6 or 12dB attenuation at fs/2 (typical in many pro
audio ADC chips) can allow audible aliasing too. I wouldn't expect
an oscilloscope to have enough resolution to detect these effects,
but a good spectrum analyser and/or a good pair of ears often can.
