Abstract
A sound reproducing device includes a decoder section () configured to decode an audio-signal bit stream input from the outside world, and to generate a decoded PCM signal; a control section () configured to identify reproduction conditions from reproduction-instruction information obtained from the outside world and decoding information obtained from the decoder section (), and to provide a reproduction instruction; and an additional-audio addition section () configured to process additional audio data input from the outside world, to add a result with the decoded PCM signal, and to output a result as an output PCM signal. The additional-audio addition section () includes an additional-audio generation section () configured to process the additional audio data so that the additional audio data can be added with the decoded PCM signal, and to output a result as an additional-audio PCM signal, and an adder () configured to mix the additional-audio PCM signal and the decoded PCM signal. The additional-audio generation section () includes a plurality of processing means (and) depending on a trade-off between the amount of load of computation process in the processing and acoustic properties of a processing result. The control section () identifies one of the plurality of processing means (and) based on the reproduction-instruction information and the decoding information. The additional-audio generation section () processes the additional audio data by the processing means identified by the control section ().
