It's an expected result. It isn't 'aliasing', but an effect called
quantisation, which you will hear even in perfectly sampled data.

[tabread4~] already goes some way towards avoiding it, by 
interpolating (going in-between the sample values) to make the
playback smoother. Since you seem interested in the low frequencies
found when slowing sounds down it might help to add a low pass 
filter that smoothes the signal even more.
