    • A computer for handling audio signals includes, within one box, programmable digital processing circuitry, read/write memory, digital-to-analog circuitry, one or more speakers, and an equalization element for altering the frequency response of signals applied to the speaker. The equalization element can be used to boost low frequency signals sent to the speaker if the speaker has poor low frequency response. Preferably the computer also has headphone and line-out jacks to which it supplies un-equalized audio outputs. The computer's internal speaker can be driven by a bridge mode amplifier, and, to save space, the speaker's electro-magnetic transducer can be placed in the concave recess formed by its speaker cones. The computer can have two speakers to play stereo. Preferably the computer receives analog inputs, such as from a built-in CD-ROM drive, a mike-in jack, and a line-in jack, and uses an analog-to-digital converter to digitizes these signals so they can be digitally manipulated by the computer. The computer preferably has a devices for selectively supplying the analog output from its digital-to-analog circuitry to either its internal speaker, headphone jack, or line-out jack. All of the computer's audio electronics can be placed on its motherboard, or they can be placed on a daughter board which plugs into the motherboard.
    • 用于处理音频信号的计算机在一个框内包括可编程数字处理电路，读/写存储器，数模转换电路，一个或多个扬声器以及用于改变施加到扬声器的信号的频率响应的均衡元件。 如果扬声器的低频响应差，则均衡元件可用于提升发送到扬声器的低频信号。 优选地，计算机还具有耳机和线路输出插孔，其提供不均衡的音频输出。 计算机的内部扬声器可以由桥式放大器驱动，为了节省空间，扬声器的电磁换能器可以放置在由其扬声器锥体形成的凹槽中。 电脑可以有两个扬声器播放立体声。 优选地，计算机接收诸如来自内置CD-ROM驱动器，麦克风插孔和线路输入插孔的模拟输入，并且使用模数转换器来数字化这些信号，使得它们可以是数字的 由电脑操纵。 计算机优选地具有用于从其数模转换电路选择性地将模拟输出提供给其内部扬声器，耳机插孔或线路输出插孔的装置。 所有电脑的音频电子产品都可以放置在主板上，也可以放置在插入主板的子板上。

    • A method of merging a first data stream with a second data stream to generate a third data stream. The method comprises receiving a first packet from the first data stream, the first packet containing a first packet ID and a first data payload and receiving a second packet from the second data stream, the second packet containing a second packet ID and a second data payload. The method also includes storing first data in a plurality of packet ID arrival registers, a first portion of the first data indicating that the first packet ID is equal to the ID associated with a first of the plurality of the packet ID arrival registers and storing second data in the plurality of packet ID arrival registers, a first portion of the second data indicating that the second packet ID is equal to the ID associated with the second of the plurality of the packet ID arrival registers. The method further includes calculating a first autocorrelation vector; calculating a second autocorrelation vector; and based at least in part upon a comparison of the magnitude of the first autocorrelation vector and the magnitude of the second autocorrelation vector, including the first packet in the third data stream.
