Abstract

Summary

Introduces the subdivision of the audible frequency range into critical bands, the psychoacoustic structure later associated with the Bark scale. Its importance for compression is foundational: perceptual codecs use critical-band masking behavior to decide which quantization noise and spectral detail can be hidden from listeners.
