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.

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

Best anti-aliasing filter to use for sampling audio on ...

My problem is: I haven't the faintest clue where to begin for a hardware anti-aliasing filter design. My instinct is to go with something with a sharp cutoff at the expense of adding some pass-band ripple. I know Matlab uses Chebyshev at 80% of the nyquist for anti-aliasing, but it looks like maybe an Elliptic filter would give even sharper cutoff?
