摘要:
An audio reproduction device includes a decoding processor to decode input voice data, a discontinuousness determination unit to determine whether or not a packet is discontinuous with a preceding packet, a reset processing unit to reset decode information, a frequency analysis unit to perform frequency analysis on the decoded data, an envelope calculation unit to calculate an envelope of the decoded data, a level difference calculation unit to calculate a level difference of the decoded data, a correction processing unit to apply a specific correction process to the decoded data if the correction process is necessary, and a processing determination unit to determine whether or not the correction process is to be performed, to determine whether or not the packet data is discontinuous, to determine which correction process is to be applied, and to output an instruction to perform the correction process.
