This article aims to explore dynamic EQ and multiband compression. They are very similar yet not exactly the same, and both shine in different specific use cases. Dynamic EQs and Multiband Compressors share common operational traits, such as threshold settings, but their underlying technical principles and processing behaviors differ significantly:
Characteristics of Multiband Compression: Band Splitting: A multiband compressor first divides the signal into several frequency bands (typically three or four). This is achieved by placing crossover filters at specific frequency points, allowing each band to be processed independently from the others. Independent Compression: Each band features its own dedicated compressor, complete with independent controls for threshold, ratio, attack, release, and makeup gain. When the signal intensity within a specific band exceeds its threshold, that band’s compressor engages, reducing the dynamic range of the signal based on its parameter settings. Output Recombination: The processed bands are then summed back together to form the final output signal.
