An audio coding apparatus comprises a frequency converter which performs frequency conversion on an audio signal to obtain frequency conversion coefficients, an importance calculator which calculates importance levels of frequency components corresponding to the frequency conversion coefficients obtained by the frequency converter, a coder which performs entropy coding of the frequency conversion coefficients to generate codes of the frequency conversion coefficients, and a comparing unit which compares an amount of the codes generated by the coder with a preset target code amount, wherein the coder performs the entropy coding in order of the importance levels until the comparing unit determines that the amount of the codes generated by the coder reaches the target code amount.
