A system and method of dynamically switching the threshold of a data queue, such as FIFO, is disclosed. The data queue has a first threshold and a second threshold, wherein the first threshold is greater than the second threshold. The data queue is dynamically switched between the first threshold and the second threshold according to different power state of a central processing unit (CPU). A system memory is requested to fill the data queue with data whenever amount of the data queue is less than the switched first/second threshold.

A method for realizing virtual multi-channel by spectrum analysis is disclosed. The low-frequency-effect sound data is obtained by averaging sound data of left and right channels in the two-channel sound source and filtering the average by a first low pass filter. The central channel sound data is obtained by averaging sound data of the left and the right channels in the two-channel sound source and filtering the average by a second low pass filter. The surround right and left sound data is obtained by copying sound data of the left and the right channels in the two-channel sound source, respectively.

A recording method for improving interrupted interferences, for use in a recording apparatus. First, a buffer is allocated, and then, the size of the buffer is checked. If the size of the buffer is smaller than a minimum recording segment, an alternative buffer is allocated; otherwise, data is recorded to the buffer. Then the data is recorded to the alternative buffer, the data in the alternative buffer is interpolated to the buffer.
