A method for processing audio signals for creating a three dimensional sound environment includes: receiving at least one input signal from at least one sound source; creating a simulated signal at least partly based on the received at least one input signal, the simulated signal representing a simulation of at least one input signal reflecting from the ground or a floor; and creating an output signal at least partly on the basis of the simulated signal and the at least one received input signal, the output signal including a plurality of audio channels; at least two channels of the audio channels of the output signal representing signals for sound transducers above a listener's ear level at a nominal listening position, and at least two channels of the audio channels of the output signal representing signals for sound transducers below a listener's ear level at a nominal listening position.

A system detects a lack of vigilance by a driver of a motor vehicle. The system includes a first monitoring unit to assess whether the vigilance of the driver is or is not above a vigilance threshold, at least two distinct loudspeakers, and a sound stage generator to control the at least two loudspeakers so as to simulate a stereophonic sound originating from a virtual sound source that is mobile relative to a seat of the driver when the vigilance of the driver becomes less than the vigilance threshold.

To enable multichannel audio data to be transmitted favorably. Multichannel audio data of a predetermined number of channels is acquired. The multichannel audio data has a sampling frequency corresponding to the predetermined number of channels. Audio data of the respective channels configuring the multichannel audio data are sequentially transmitted to a reception side via a predetermined transmission channel for each unit audio data. Information indicating the sampling frequency is added to the transmission audio data.

Disclosed is a binaural audio signal processing device. The binaural audio signal processing device includes a binaural renderer and an extra exciter. The binaural renderer receives an audio signal, and outputs a binaural-rendered audio signal by performing binaural rendering on the received audio signal. The extra exciter generates a stimulation to a body of a user, wherein the stimulation corresponds to the binaural-rendered audio signal.

Disclosed is a method and a system to determine an audio precompensation controller for an associated sound generating system including a total of N≧2 loudspeakers, each having a loudspeaker input. The audio precompensation controller has a number L≧1 inputs for L input signals and N outputs for N controller output signals, one to each loudspeaker.
