Beat cancel (BC), as its name implies, is designed to cancel unpleasant beat interference. Like NR1
(line enhancer), BC uses adaptive filter technology. With this technology BC tracks and cancels a
beat signal just like shaping a band elimination filter.
BC is especially effective when there are multiple beats that are equivalent to or lower in strength
than the target signal. The adaptive filter can self-adjust its characteristics while tracking multiple
beats and effectively cancel them.
