摘要：A bit-rate converting apparatus and a method thereof, in which bit-rateconversion is executed by low computational complexity, are provided. The bit-rateconversion is executed in a frequency domain, and psycho-acoustic analysis is not neededby using information included in an inputted bit-stream before the bit-rate conversion isapplied. With this, the computational complexity is lowered. And in order that many equalvalues are not contained in a frequency domain signal, which is inputted to a quantizingmeans, a quantized value before inverse quantizating is applied is modified, or an inversequantized value after the inverse quantizing was applied is modified. With this, finecontrol for the bit-rate is made to be easy.
