The present invention overcomes the serious practical limitations inherent in presently-existing RAM-based audiovisual effects processing systems for essentially instantaneous playback of data. The method of the invention divides individual audio effects into two discrete segments, and stores these two segments in a distributed storage system. The first segment of an effect is stored in memory, allowing nearly instantaneous access and playback of this segment. The second segment is stored in a storage device with a relatively long access time. In operation, the first portion of the effect is played from memory, while the second portion is simultaneously retrieved from storage, such that the second portion is retrieved and is available for playback by the time the playing of the first segment terminates. Playback of these two segments in perfect succession effectively furnishes instantaneous playback of audio data, while reducing cost, facilitating loading of effects data, and providing further operational advantages. The disclosed method and apparatus is equally suitable for implementing essentially instantaneous playback of video or audiovisual data.
