Quite often, an anti-aliasing filter takes the form of a low pass filter. The issue here is that when you cut the problematic frequencies, you also cut the desirable frequencies above the cutoff point. The best way to deal with aliasing …

The anti-aliasing would have a cut-off frequency of 20 KHz, but since this is not an ideal filter usually the sampling frequency used goes from 44.1 KHz to 96 KHz, allowing a transition band of at least 2 KHz. An illustration of an anti-aliasing filter being applied to a raw signal is shown below. Say that you want to sample f1 and f2 only.

The anti-aliasing filter used may have a bandwidth of 20 kHz but the response is 40 dB down starting from 24 kHz. This means that the minimum sampling frequency has to be increased to 48 kHz instead of 40 kHz for the ideal filter. Alternatively, if we fix the sampling rate, then we need an anti-alias filter with a sharper cut-off.

Could these effects - producing very small errors in the sub-20kHz audio band - explain any of the reported differences between 44.1kHz and 96kHz sampled systems? [1,2,3,4] If these aspects are relevant then how should the design of anti-alias and anti-image filters for 96kHz sampled systems differ from those for 44.1kHz sample rate systems?

ES AntiAlias is a free plugin that filters out harmonics that occur above the nyquist frequency by oversampling the input signal and then filtering. If you are using any instruments or effects that generate aliased digital audio (many of them) ES AntiAlias can improve the sound quality.
Anti-aliasing filter - Wikipedia
https://en.wikipedia.org/wiki/Anti-aliasing_filter
Audio applications Anti-aliasing filters are used at the input of an analog-to-digital converter. Similar filters are used as reconstruction filters at the output of a digital-to-analog converter. In the latter case, the filter prevents imaging, the reverse process of aliasing where in-band frequencies are mirrored out of band. Oversampling

Anti-Alias Low Pass Filtering – this process attempts to filter out the frequencies that exceed the Nyquist frequency from the input signal. These frequencies would otherwise be folded back into the audio range. The effectiveness is contingent upon the current sampling rate.
