A spectral transformation that remaps a linear frequency axis (Hertz) onto a non-linear perceptual frequency scale. The transformation applies a monotonic function f(frequency) where the output scale approximates human auditory perception — the mel scale uses f(f) = 2595·log₁₀(1 + f/700), the bark scale uses critical-band boundaries, and the ERB scale uses equivalent rectangular bandwidths. The parameters are the target perceptual scale and the input spectrum; persistence is achieved through standard implementation in DSP libraries and audio processing toolkits.

    Definition correctly carves freq-warping as a spectral transformation remapping linear frequency axis to perceptual scale. States the mechanism (monotonic function) and persistence. Law 4-6 satisfied.

    The definition correctly describes freq-warping as a spectral transformation remapping linear frequency to perceptual scales via a monotonic function. It carves the concept with parameters and includes the Law 6 trailer. Good.

    Definition of 'freq-warping' properly carves: remaps linear frequency axis onto non-linear perceptual scale via monotonic function. Ends with Law 6 trailer. Well-formed definition.

    Definition properly carves freq-warping (remapping linear to non-linear perceptual frequency scale). Clear parameters (monotonic function), persistence mechanism (algorithmic implementation), correct Law 6 trailer. Well-formed.
