Abstract:
A solid-state audio recording unit for outputting, while storing incoming audio data into a memory, audio data stored in the memory on a real-time basis, said solid-state audio recording unit comprising:two input buffers for alternately holding incoming audio data; a memory for storing audio data; two output buffers for alternately holding audio data read from the memory; and control means for controlling the two input buffers and the two output buffers, said control means, during a period, controlling one of the two input buffers to hold audio data according to a reference clock, and one of the two output buffers to output audio data according to the reference clock, during a first part of the period, controlling the audio data held by the other input buffer to be written into the memory according to a second clock having a higher frequency than the reference clock, and, during a residual time of said period other than said first part, controlling audio data already written into the memory to be read from the memory and written into the other of the two output buffers according to a third clock having a higher frequency than the reference clock, said control means repeating the same operation alternately between the two input buffers and the two output buffers.
