Because at this stage (before the sampler and the ADC) you are still in the analog world, the anti-aliasing filter is an analog filter. An ideal anti-alias filter passes all the appropriate input frequencies (below f1) and cuts off all the undesired frequencies (above f1). However, such a filter is not physically realizable. In practice, filters look as shown in illustration (b) below. …

To eliminate this you need a lowpass filter with cutoff of 20 kHz at 192 kHz sample rate and sufficient attenuation at 24 kHz. Finally you just down sample the result by factor of three by simply throwing away every second and third sample. This works without aliasing, since the lowpass filter has already eliminated all content that would alias.

Typically an analog anti-aliasing filter is used to band-limit wideband signals at the input of an analog-to-digital converter. In addition, as the converter’s sampling rate changes, an anti-aliasing filter’s passband should increase or decrease accordingly.

To remove aliasing, you need to use an anti-aliasing filter. 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 is by preventing it, but if you can’t, your next best move is to apply an …
Which anti aliasing filter algorithm for efficient audio ...

I'm building a real-time audio resampler (think pitch bend) that needs to have a several different performance vs quality configuration options. I understand that I'll need to apply a low-pass filter before resampling in order to avoid aliasing. The requirements for the first filter are this: very efficient; better than nothing
