Abstract
There is disclosed a device that can record a sound by selecting a directivity direction as desired by the user at the time of recording and can play back the sound by selecting, at the time of playback, a desired directivity direction by the user, separate from the directivity direction specified at the time of recording. The device has microphones, a touch panel for specifying a directivity direction, and a signal processing unit. A recording module performs directivity control in a direction specified on the touch panel and records audio data subjected to effect processing in a memory as directivity-controlled data, and records audio data that are not subjected to directivity control or effect processing in the memory as directivity-control unprocessed data. A playback module performs directivity control on the directivity-control unprocessed data recorded in the memory in a direction specified on the touch panel at the time of playback and performs effect processing on the resulting data, and plays back and outputs them.
