摘要： An audio codec in a wireless device may be utilized for up sampling two or more audio signals to a same data sampling rate. Each audio signal, such as digital audio, voice, and polyringer, for example, may be received at one of a plurality of data sampling rates. Audio signals may be equalized and/or compensated with an FIR filter before up sampling or with an IIR filter to reduce overall processing latency. Multiple half-band interpolation operations may perform the up sampling. The first half-band filter may be replaced by an IIR filter to reduce overall processing latency. A gain of the up-sampled data may be adjusted to reduce noise effects. The channels of the up-sampled audio signals may be mixed and later further up sampled for subsequent communication to an output device. The up-sampled mixed audio signals may be down sampled for communication to a Bluetooth radio.

摘要： One or more circuits in a mobile phone may be utilized for up sampling two or more audio signals to a same data sampling rate. Each audio signal, such as digital audio, voice, and polyringer, for example, may be received at one of a plurality of data sampling rates and one or more of the following wireless standards: WCDMA, HSDPA, GSM, GPRS, EDGE, and/or Bluetooth. Audio signals may be equalized and/or compensated with an FIR filter before up sampling or with an IIR filter to reduce overall processing latency. Multiple half-band interpolation operations may perform the up sampling. The first half-band filter may be replaced by an IIR filter to reduce overall processing latency. A gain of the up-sampled data may be adjusted to reduce noise effects. The channels of the up-sampled audio signals may be mixed and later further up sampled for subsequent communication to an output device.
摘要翻译：移动电话中的一个或多个电路可用于将两个或多个音频信号上采样到相同的数据采样率。可以以多种数据采样率和以下无线标准中的一种或多种以下无线标准中的一种来接收每个音频信号，例如数字音频，话音和多声道，WCDMA，HSDPA，GSM，GPRS，EDGE和 /或蓝牙。音频信号可以在上采样之前用FIR滤波器或IIR滤波器进行均衡和/或补偿，以减少整体处理等待时间。多个半带插值操作可以执行上采样。第一个半带滤波器可以被IIR滤波器代替，以减少整体处理等待时间。可以调整上采样数据的增益以减少噪声影响。上采样音频信号的信道可以混合并且稍后进一步上采样以便随后与输出设备进行通信。
