基于随机出现的音频源产生扬声器信号的设备和方法
摘要：
一种用于针对多通道再现环境中的扬声器通道而产生扬声器信号的粒子产生器，包括：位置产生器(14)，用于提供音频源要出现的多个位置；以及时间产生器(18)，用于提供音频源要出现的出现时间，该时间与位置相关联。此外，提供了单个脉冲响应产生器(16)，用于针对多个位置中的每个位置，产生单个脉冲响应信息。组合脉冲响应由脉冲响应组合器(20)形成，脉冲响应组合器(20)用于根据出现时间来组合单个脉冲响应信息。该整体脉冲响应最终用于调节滤波器(21)，最终利用滤波器(21)，对音频信号进行滤波。
摘要（英）：

Disclosed is a particle generator for generating a loudspeaker signal for a loudspeaker channel in a multichannel reproduction environment. Said particle generator comprises a position generator (14)for providing a plurality of positions in which an audio source is to occur, and a time generator (18) for supplying times during which the audio source is to occur, a time being allocated to a position. An individual pulse response generator (16) is also provided for generating individual pulse response data for each of the plurality of positions. A combined pulse response is formed by a pulse response combining unit (20) to combine the individual pieces of pulse response data according to the times during which the same occur. Said combined pulse response is finally used for adjusting a filter (21), with the aid of which the audio signal is finally filtered.
