摘要： This invention relates to reformatting a plurality of audio input signals from a first format to a second format by applying them to a dynamically-varying transformatting matrix. In particular, this invention obtains information attributable to the direction and intensity of one or more directional signal components, calculates the transformatting matrix based on the first and second rules, and applies the audio input signals to the transformatting matrix to produce output signals.

摘要： The loudness of an audio signal is adjusted while reducing changes in its perceived spectral balance, using a dynamically-controllable filter having a high-frequency response characteristic and a low-frequency response characteristic, controlled by dynamically-changing information on the desired gain in each of a plurality of frequency bands of the audio signal.
