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?
