Abstract

The invention provides an audio reproduction device, information reproduction system, audio reproduction method. The 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. The invention can reduce the pause in the audio reproduction due to the mute and make the reproduced audio sounded more comfatable.

Description

[0001] Cross References to Related Applications [0002] This application contains subject matter related to and claims priority from Japanese Priority Patent Application No. JP2009-008250 filed in the Japan Patent Office on January 16, 2009, the entire contents of which are hereby incorporated by reference. technical field [0003] The present invention relates to an audio reproduction apparatus, an information reproduction system, an audio reproduction method and a program for audio reproduction of a CD player, a DVD player, a television or the like. Background technique [0004] In an audio (speech) reproducing apparatus, if a discontinuous stream of voice data is reproduced, noise is generated at the discontinuity point, causing discomfort to the listener. [0005] To solve this problem, usually, as figure 1 As shown, the voice signal is muted before and after the discontinuity point to prevent noise generation (for example, see Japanese Unexamined Patent Application Pu...
