"Audio signals often contain DC offset. DC offset is often not easy to recognize when using an audio editor. Offset correction can reduce the magnitude of a signal while maintaining the loudness. This is a potentially useful trick when mastering a track or when fighting in the loudness wars.

Doffset is specially designed to minimize any coloration to the signal and, at the same time, quickly adjust the signal to remove any DC offset. Doffset offers three modes of operation, each giving a slightly different trade-off between bass response and zero DC convergence time."
