PROBLEM TO BE SOLVED: To provide a sound encoding method which realizes real-time processing even in a general CPU and to which a variable data length acoustic signal can be inputted. SOLUTION: Four sampled 16-bit data 101 to 104 are converted to 8-bit data 105 to 108, and they are packed in 32-bit registers by fours to generate chain data 109. Chain data 109 is processed to obtain chain data 110. Data are separated from chain data 110 to obtain 8-bit data 111 to 114, and the data length is converted to obtain 16-bit data 115 to 118. |
