Claim Text:
1. A method for signal processing, the method comprising: mixing audio signals in an audio codec integrated within a baseband processor in a wireless device to provide a mixed audio signal, wherein said audio signals are received in said audio codec at a plurality of data sampling rates; up-sampling said mixed audio signal to a sampling rate that is higher than the sampling rate of each of said audio signals to provide an up-sampled mixed audio signal; down-sampling said up-sampled mixed audio signal to a specified output sampling rate using a linear interpolator to provide a down-sampled mixed audio signal; and triggering said linear interpolator at appropriate times to interpolate a new output sample of said down-sampled mixed audio signal based on a ratio of the sampling rate of said up-sampled mixed audio signal to said specified output sampling rate.
