A non-sprocketed tape recorder (analog or digital) that records and plays back eight or more tracks. The most common analog format is 24 tracks on 2-inch tape, frequently with some form of noise reduction. The digital world is shared between the DASH (Digital Audio Stationary Head) format, with 1/2-inch tape recording either 24 or 48 tracks, and the PD (ProDigital) format, recording 32 tracks on 1-inch tape. Modular digital multitracks use video cassettes to store 8 to 12 tracks of audio. Locking together multiple transports can provide up to 128 tracks in a standard configuration.
