MaxMatch automatically balances the left and right channels and maximizes the volume levels. Essentially, this effect uses the effect internally on the left and right channels, then uses the effect. After processing, the left and right channels will have the same average level and at least one channel will have full dynamic range (1.0 or 0dB).

Note that it is rarely possible for all channels to have the same average and full dynamic range at the same time. Most channels will have a dynamic range of slightly less than 1.0 or 0dB.
