The AVA Multiband Compressor is the latest implementation of Harrison’s renowned Multiband Compression algorithm, as used in ultra high-end post & film facilities worldwide. Now in the fourth generation, the Harrison Multiband Compression algorithm has been continuously tweaked by their customers in high-end music, film, broadcast, and video-post production.

Harrison’s reputation for "True Analog In-The-Box" sound is due to their unique development heritage: they first created an analog console processor and then converted the processor to digital while retaining the sound and character of the original analog console.
