remix_and_resample effect optimization

[wyz-honey]

                if isinstance(data, rtc.AudioFrame):
                    # TODO(theomonnom): The remix_and_resample method is low quality
                    # and should be replaced with a continuous resampling
                    frame = data.remix_and_resample(
                        self._sample_rate, self._num_channels
                    )

When will this TODO be optimized? After testing, the accuracy of this solution is much different from that of using pyaudio to read data from the microphone.
