Warp Processing™

Warp Processing is the way that ReSound chooses to process sound. ReSound was the first and only manufacturer to base amplification on an accurate model of cochlear frequency analysis.
Warp Processing emulates the way the unaided ear analyzes the frequencies of incoming sound and breaks them into distinct pitches. It does this by decoding thefrequencies and intensities of sounds in a nonlinear way – the same way the ear does.

Most digital techniques for frequency analysis yield constant bandwidth with uniform spacing of the bands, but Warp Processing maps the frequencies into 17 smoothly overlapping frequency bands which match the resolution of the cochlea and correspond to the auditory Bark scale. (The Bark scale incorporates the human auditory system’s critical bandwidth as the scale unit.)
Warp processing is very important in capturing an accurate assessment of the environment. With a short processing delay and smooth frequency response, this feature provides patients with a clear, balanced sound quality that is virtually distortion free.
