System for modifying an acoustic space with audio source content

摘要

An audio signal processing system is configured to separate an audio signal into a dry signal component and one or more reverberant signal components. The dry signal component and the reverberant signal components can be separately modified and then recombined to form a processed audio signal. Alternatively, the dry signal component may be combined with an artificial reverberation component to form the processed audio signal. Modification of the reverberation signal component and generation of the artificial reverberation component may be performed in order to modify the acoustic characteristics of an acoustic space in which the audio signal is driving loudspeakers. The audio signal may be a pre-recorded audio signal or a live audio signal generated inside or outside the acoustic space.

主权项

1. An audio signal processing system for modifying an acoustic space with audio source content, the audio signal processing system comprising:
a processor; a memory in communication with the processor; the memory configured to store a plurality of modules executable by the processor, the modules comprising:
a reverberation generator module configured to adjust an early reflection of an audio signal to modify a user perceived height of a ceiling of a listening space;a signal modification module configured to create a multi-channel output signal based on the adjusted audio signal, the multi-channel output signal comprising a first channel output signal configured to drive a first loudspeaker positioned in a listening space above a listener, and a second channel output signal configured to drive a second loudspeaker positioned in the listening space below an elevation of a listener's ears.
