measures sub, low bass, mid bass and low mids in third-octave steps, then lifts or lowers each zone, notches single droning resonances and keeps the low end mono and in phase.
balances everything above the bass against the reference. in auto mode every track is analyzed on its own and keeps its character while the faults get fixed.
adjusts compression so the track carries the punch and energy of the reference.
lifts the audio to a clean, competitive level while guarding against digital distortion.
removes dc offset and filters sub-bass rumble below 23 hz.
writes 24 bit wav files built for smooth playback on every system. several tracks are mastered one after another against the same reference and arrive as one zip.
