ABSTRACT:
In a digital recorder, a signal process can be performed on digital audio data track by track or event by event in a recording mode or in a reproducing mode. In the recording/reproducing mode, transfer of digital audio data between a hard disk and respective audio input/output devices is executed in real time under control of a DMA controller and a HD controller. A DSP provided between the DMA controller and the HD controller performs the signal process such as a filtering process on digital audio data (block data) of several samplings in a lump, which are transferred (DMA transfer) in a lump between the buffer and the hard disk.
