摘要： An apparatus for decoding an encoded multichannel signal of a current frame to obtain three or more current audio output channels is provided. A multichannel processor is adapted to select two decoded channels from three or more decoded channels depending on first multichannel parameters. Moreover, the multichannel processor is adapted to generate a first group of two or more processed channels based on said selected channels. A noise filling module is adapted to identify for at least one of the selected channels, one or more frequency bands, within which all spectral lines are quantized to zero, and to generate a mixing channel using, depending on side information, a proper subset of three or more previous audio output channels that have been decoded, and to fill the spectral lines of frequency bands, within which all spectral lines are quantized to zero, with noise generated using spectral lines of the mixing channel.

摘要： A method for processing an audio signal (504) in accordance with a room impulse response is described. The audio signal (504) is processed (502) with an early part of the room impulse response separate from a late reverberation of the room impulse response, wherein the processing (514) of the late reverberation comprises generating a scaled reverberated signal, the scaling (526) being dependent on the audio signal (504). The processed early part (506) of the audio signal (504) and the scaled reverberated signal are combined.

摘要： An apparatus for processing an audio input signal comprising one or more audio channels to obtain an audio output signal according to an embodiment is provided. The apparatus comprises a reverberation gain determiner (110) configured to determine reverberation gain information depending on the audio input signal. Moreover, the apparatus comprises a signal processor (120) configured to obtain the audio output signal depending on the reverberation gain information by adding artificial reverberation to the audio input signal or to a preprocessed audio signal, which depends on the audio input signal.
