Patent ID: 7043440

Claim:
A play back apparatus in which, according to a play back command from an operation section, the PCM audio data is generated from compression data in which the audio information is coded, and an audio is played back according to the PCM audio data, said play back apparatus comprising: a control section for conducting the control of each section of said apparatus according to each kind of commands from an operation section; a compression decoder for decode processing the compression data, generating the PCM audio data, and successively outputting thereof; a first storage section for successively renewing the temporarily stored data successively generated according to the PCM audio data and temporality storing thereof, and appropriately repeatedly reading out the temporarily stored data which is temporarily stored, and successively outputting thereof; and a switching section for selecting either one of the PCM audio data successively outputted from said compression decoder or the temporarily stored data stored in said first storage section, and outputting thereof, wherein when a quick traverse play back command or quick returning play back command is given by said operation section, (1) said control section controls said switching section and selectively outputs the temporarily stored data stored in said first storage section and (2) said switch section outputs a special audio data, wherein the special audio data is an imitation sound into which the quick traverse play-back of the audio information is converted.
