A frequency scale that transforms linear Hertz values to a perceptual mel scale using the formula m = 2595 × log₁₀(1 + f/700), where f is frequency in Hz. The scale approximates the human auditory system's non-linear frequency resolution and persists through computational implementations in audio processing toolkits and standardization in speech and audio analysis pipelines.

Definition
Why it is in scope
A human-made frequency scale used in audio and music processing that maps linear frequencies to a perceptual scale approximating human hearing. Developed by Stevens, Volkmann, and Newman (1937), it is the foundation for mel-scale filtering and the mel-frequency cepstrum. Built to persist because it standardizes perceptually-motivated frequency representations across speech recognition, audio analysis, and music information retrieval.

mel-frequency-scaled IS a specific kind of frequency-scale: it maps frequencies to a perceptual (non-linear) axis using the mel formula. A competent speaker would call it 'a frequency scale.'

Mel-frequency-scaling is built and maintained for the sake of speech-recognition — it maps frequencies to a perceptual axis that approximates human auditory filtering, forming the basis of MFCC features central to ASR systems.

Mel-frequency scaling IS a specific kind of frequency warping — it warps the linear frequency axis into the perceptual mel scale. A competent speaker calls mel-frequency scaling 'a frequency warping' method. Nearest-kind INSTANCE_OF.
