A Native Stereo Editing System for Direct-Stream Digital

The editing in native form of 2.8224 MHz 1-bit audio (Direct Stream Digital) is problematic since the required computation rate to achieve level control, pan, and crossfade in real time is beyond the capabilities of general-purpose digital signal processing chips. A system has been developed which incorporates a special-purpose chip designed specifically for computations on 1-bit audio. This is embedded into the framework of a general-purpose audio editing and premastering system. It behaves, looks, and feels exactly like a stereo, PCM editing system with full flexibility of sample-accurate cross-fades, level control, metering, and nonlinear random-access editing, except that internally it is operating directly on the 1-bit signal. This paper describes the data flow and architecture of the system.
