Abstract
We propose AI Audio Engineering as an emerging discipline that extends classical digital signal processing (DSP) and physical modeling with data-driven inference, perceptual evaluation, and lifecycle operations for audio artifacts. The framework is motivated by two demonstrators. The first applies measurements of plucked-string instruments to derive modes, coupling terms, and nonlinearities that constrain a dual-polarization digital waveguide model together with a neural residual surrogate. The experimental setup, measurement protocol, and signal-processing pipeline are described in detail. The second demonstrator embeds real-time finite-difference time-domain and digital-waveguide models in an extended-reality (XR) environment via the SIVE Toolkit, using haptic controllers and binaural room acoustics. The XR platform functions both as a performance surface and as an instrumented data-collection system for perceptual evaluation and player-in-the-loop adaptation. We argue that measurement, physical modeling, learning, and perceptual evaluation form a continuous loop in which audio models become deployable, maintainable, and continuously improvable artifacts, closing the industry-reported gap in which a large fraction of (audio) ML models never leaves the experimental stage. Implications for the Audio Engineering community are discussed.
