Uses filters modelled on the logarithmic organization of the human cochlea with narrower filters at low frequencies, where sensitivity is high, and broader filters at higher frequencies.

– Variable-width filters mimic the human ear
– Enables low processing delay

Suited to listeners who prefer authentic, more natural sound clarity.

Analyses sound using relatively narrow, uniformly spaced filters, enabling detailed parallel spectral analysis and efficient processing.

– Extra processing power
– High-resolution data processing

Often favored by listeners who prefer enhanced speech contrast and foreground focus.
