From DSP to AI: Evolving Approaches in Audio Processing
Introduction: Audio as a First-Class Intelligence Modality Audio is one of the most information-dense and perceptually sensitive modalities through which humans interact with the world. Unlike vision or text, audio is continuous in time, governed by physical acoustics, and immediately evaluated by the human auditory system with millisecond-level sensitivity. These properties make audio uniquely challenging for artificial intelligence systems. Even small distortions—phase discontinuities, temporal smearing, and spectral artifacts—can result in degraded intelligibility, listener fatigue, or loss of immersion. […]
