Embodiments of the invention achieve increased compression of audio data in comparison to prior art ADPCM compression schemes using modest processing power and resources. For one embodiment, an asymmetric ADPCM encoding scheme is implemented to increase apparent encoding resolution for a specified number of encoding bits. Additionally, or alternatively, such techniques as pattern recognition and encoding, as well as calculation simplification, are employed to increase data compression of audio data.
