Hi Brittany,
Most forms of pitch-shifting shift the fundamental and all harmonic
frequencies proportionally.  So when you shift the F0 of a male speaker up
by 4 semitones, it will sound like the voice of a person with a higher
pitched voice. It will sound very natural and understandable.

I don't know how audacity or garage band would do the shifting; they may
do it differently than other commercial devices, but you could easily
measure the signals before and after to determine which frequencies (F0
and harmonics) were shifted.

Best regards,

Chuck
