Apparatus and method for storing and retrieving audio data simultaneously. A digital audio logger is provided with a digital audio tape (DAT) for permanent storage of audio data and with a random access storage (RAS) device that provides fast retrieval of audio. Both the DAT and RAS devices have audio written from a buffer that initially stores audio data temporarily. Two pointers are provided for the RAS device. Because of the randomness characteristic of the RAS device, data can be retrieved rapidly with a first one of the pointers and for this reason has advantages in fast retrieval. The RAS device communicates with a supervisor whereby data can be retrieved therefrom through the first pointer while the RAS device is receiving data from the buffer through the second pointer.
In a method of storing and retrieving audio from a digital audio logger, the steps comprising:
In a system for processing audio having an interface for receiving audio from an audio source, a digital signal processor in communication with the interface for compressing the audio signals, a controller in communication with the digital signal processor for receiving audio therefrom and arranging data in a prescribed order, a supervisor in communication with said controller accessing data from said system, and a buffer in communication with the controller for receiving arranged audio from the controller, the improvement comprising:
An audio data storage device, comprising:
