System and methods for motion restoration in acoustic processing of recorded sounds

摘要

A motion signal processing technique modifies digital audio recordings in order to restore a sense of motion, liveliness, and spatial dynamics. The technique compensates for the static presentation of sound created by modern recording and sound synthesis techniques and common modern playback equipment such as headphones and ear buds in order to create a more natural, immersive, and enjoyable listening experience.

1. A method for adjusting perception of recorded sounds, comprising:
detecting a transient signal within an input audio waveform, the transient signal having associated transient signal characteristics; selecting a motion simulation based on the detected transient signal characteristics, the motion simulation having associated motion simulation parameters; selecting the motion simulation parameters using the transient signal characteristics to reduce the perception of motion simulation; and applying a motion simulation processing algorithm, using the selected motion simulation and motion simulation parameters, to generate an output audio waveform.
