Hybrid noise shaping for audio coding using perfectly overlapped window
In recent years, audio coding technology has been standardized based on several frameworks that incorporate linear predictive coding (LPC).
Audio coding with unified noise shaping and phase contrast control
As LPC reduces information in the frequency domain, LP-based frequency-domain noise-shaping (FDNS) was previously proposed.
HARP-Net: Hyper-Autoencoded Reconstruction Propagation for Scalable Neural Audio Coding
The assumption is that, in a mirrored autoencoder topology, a decoder layer reconstructs the intermediate feature representation of its corresponding encoder layer.
Psychoacoustic Calibration of Loss Functions for Efficient End-to-End Neural Audio Coding
Conventional audio coding technologies commonly leverage human perception of sound, or psychoacoustics, to reduce the bitrate while preserving the perceptual quality of the decoded audio signals.
