    • An audio system includes a general-purpose computer in the audio signal path to provide, or to enhance, pre-amplification functions. In one embodiment, in response to audio signals from a pre-amplifier, a programmable multimedia controller including the general-purpose computer generates control commands and passes these control commands via a signal path back to the pre-amplifier. In a second embodiment, rather than control a separate pre-amplifier, the programmable multimedia controller itself implements the pre-amplification functions. In yet another embodiment, a power amplifier includes the general-purpose computer and pre-amplification functions are implemented there. Also, a display screen shows a virtual control panel that is used to control the pre-amplification of audio signals. The virtual control panel provides a graphical user interface that simulates, replicates, or replaces with an alternate arrangement, the physical controls and readouts found on the control panel of a physical device. Audio-interactive graphics, images and/or artwork may also be shown on the display screen.
    • 音频系统包括音频信号路径中的通用计算机,以提供或增强预放大功能。 在一个实施例中,响应于来自前置放大器的音频信号,包括通用计算机的可编程多媒体控制器生成控制命令并将这些控制命令经由信号路径传递回前置放大器。 在第二实施例中,不是控制单独的前置放大器,而是可编程多媒体控制器本身实现预放大功能。 在又一个实施例中,功率放大器包括通用计算机,并且在那里实现预放大功能。 另外,显示屏幕显示了用于控制音频信号的预放大的虚拟控制面板。 虚拟控制面板提供了一个图形用户界面,用于模拟,复制或替换备用安排,物理设备控制面板上的物理控制和读数。 音频交互式图形,图像和/或艺术作品也可以显示在显示屏上。
