Yes, aliasing is related to frequency. Sampling theorem states that
sampling rate must be twice as the higher frequency of the sound you
want to reproduce. If the sampling rate is too low, high frequencies
in your sound will give low frequencies in the sample : high frequencies
will be _aliased_ to lower frequencies.

With 4 bits, you can have 16 differents values. Thus, it will be hard to
reproduce a smooth sinusoide with only 16 values and your sound will be
altered and will sound "lo-fi".

In fact, sampling rate and resolution are both important to reproduce
acurately a sound.

I hope this clear (sorry for my english... not my native language :-(
