Abstract
The present invention relates to a system and a method for reducing access times for retrieving audio samples. The system uses a wave table cache. The wave table cache allows devices such as a Digital Signal Processor (DSP) to retrieve audio samples in a linear fashion from the wave table cache at a rate much faster than individually fetching the required portions of the audio sample from the main memory of the system. The DSP may then use the audio samples to generate signals to create sounds based on the audio samples.
