An electronic filter circuit that divides an audio signal into separate frequency ranges. Speaker systems use active or passive crossovers to direct certain frequencies to the woofer or tweeter. Multiband audio processors use crossovers to divide the audio into frequency ranges to be processed independently. A deesser, for example, uses a crossover filter to separate high frequencies, which may be compressed, from lower frequencies which pass through unaffected.
