ALC-Record means Automatic Level Control Record. The ALC is the automatic level control many tape decks have to automatically control the level to avoid too low level (causing increase of noise) and too high level (causing disturbance by clipping the wave).
For recording of LPs or MCs to write a CD it is important that the maximum level is never exceeded, because digital clipping makes distortions of the sound. But if the level is too low you have to normalize the file and this amplifies the noise. With many meters you cannot view the record level good enough for exact level control.
This program pulles down a selectable level control of the soundcard's mixer if the maximum level is reached (and may pull it up if the sound gets more quiet later), this guarantees an optimal record level. It can also be used if you have more than one soundcard (some programs get in trouble then).
