Abstract
An audio processor is provided which includes a digital signal processor for processing a digital audio data in an inputted digital audio file and a digital analog converter for converting the digital audio data processed by the digital signal processor into an analog audio data in accordance with a sampling frequency of the digital audio data. The digital signal processor adds a silent data of predetermined amount of time which is the same or longer as time for completing a setting of the sampling frequency in a beginning of the digital audio data in the inputted digital audio file.
Claims6
An audio processor for converting a digital audio data in an inputted digital audio file into an analog audio data, comprising:
- a digital signal processor for processing a digital audio data in an inputted digital audio file;
- and
- a digital analog converter for converting the digital audio data processed by the digital signal processor into the analog audio data in accordance with a sampling frequency of the digital audio data;
- and
- a controller for controlling an operation of the audio processor, wherein
- when the controller judges that a digital audio file is inputted to the digital signal processor, the digital signal processor adds a silent data of time which is the same or longer as time for completing a setting of the sampling frequency in the digital signal processor in a beginning of the digital audio data in the inputted digital audio file;
- wherein the digital signal processor outputs processed digital audio data, to which the silent data was added, to the digital analog converter at a predetermined frequency until the setting of the sampling frequency is completed, and after the setting of the sampling frequency is completed, the digital signal processor outputs the processed digital audio data to the digital analog converter at a set sampling frequency.
