Is it an homework?
In any case:
increasing sample rate: audio reproduction is more accurate but memory occupation is higher
decreasing sample rate: memory occupation is lower but audio reproduction is less accurate

I'd argue that bit depth (resolution) has more to do with audio being more accurate, not sampling rate. A lower sample rate simply means that the maximum (Nyquist) frequency will be lower (half the sampling rate) – dsp_user May 22 '17 at 13:50
