A device includes a receiver configured to receive an inter-channel prediction gain parameter and an encoded audio signal. The encoded audio signal includes an encoded mid signal. The device also includes a decoder configured to generate a synthesized mid signal based on the encoded mid signal. The decoder is configured to generate an intermediate synthesized side signal based on the synthesized mid signal and the inter-channel prediction gain parameter. The decoder is further configured to filter the intermediate synthesized side signal to generate a synthesized side signal.
