Abstract (en)
[origin: WO2004047486A2] The invention relates to a device, which is provided for determining a pulse response in an environment, inside of which a loudspeaker (10) and a microphone (12) are placed, and which operates while using an audio signal. A device (20) for effecting the spectral coloring of a test signal, which is preferably a pseudo noise signal, operates while using a psychoacoustic masking threshold of the audio signal in order to obtain a colored test signal that is embedded in the audio signal in order to obtain a measurement signal that can be fed to the loudspeaker (10). A device (30, 32) for determining the pulse response preferably carries out a cross-correlation of a reaction signal, which is received from the environment via the microphone, and of the test signal or of the colored test signal. This enables a pulse response of an environment to be determined even while playing an audio piece in order to provide an optimal description of the environment for a wavefield synthesis.
