Audio signal processors, systems and methods that distribute ambient signals across multiple ambient signal channels

摘要

An audio signal processor for providing an ambient signal channel based on an input audio signal is configured to extract the ambient signal based on the input audio signal. The signal processor is configured to distribute the ambient signal to multiple ambient signal channels, depending on the position or orientation of the sound source within the input audio signal, and the number of ambient signal channels is greater than the number of channels of the input audio signal. ..
