Yes. A compressor is like someone turning down the volume if it exceeds
a certain treshold and turning it back to normal when it drops below it.
This means that loud peaks are not so strong anymore while the rest
still has normal volume. With those peaks being gone, you could
normalize the waveform again to raise its overall volume. There won't be
clipping because the peaks are gone.
