Microphones are used to record speech which can then be recognized by software to allow dictation or computer control. Digital cameras capture images electronically in JPG format on memory cards for use in various professions, while digital video cameras do the same for moving images in MP4 format. MIDI connects musical instruments to computers for digital music recording and playback at a professional level.
