Abstract

The invention relates to an audio signal processing device (100) for processing a plurality of audio signals (105) defining the frequency spectrum of a plurality of audio signals, the audio signals being sent to a listener so that the listener perceives that the audio signal comes from a plurality of audio signals (105). virtual location of an audio source. The audio signal processing apparatus comprises: a selector (101) for selecting a spatial arrangement relative to the virtual position of the audio signal source of the listener from a plurality of possible spatial arrangements; a filter (103) for selecting a spatial arrangement based on the selected spatially arranged to filter the plurality of audio signals.

Description

technical field [0001] The present invention relates to an audio signal processing device and method. In particular, the present invention relates to an audio signal processing device and method for a virtual space audio conference system. Background technique [0002] In the past, the sound from the speakers in a multiparty audio conferencing system was often presented to the listener as a mono audio stream - which was basically stacked on top of each other, and when using headphones it was usually presented "inside" the listener's head. [0003] The virtual space audio conferencing system is a special form of multi-party teleconferencing defined by ITU-T recommendation P.1301 "Subjective quality assessment of audio and audio-visual multi-party teleconferencing", which realizes 3D audio rendering of participants' voices. That is, by employing the head-related impulse response (HRIR) or its corresponding frequency-domain representation, the head-related transfer function (H...
