A new audio coding tool that uses improved time scaling synthesis techniques has been developed which reduces the duration of pre-noise introduced by low-bit rate audio coding of transient material. When transient pre-noise reduction processing is used, decoded PCM audio located prior to transient material is processed in the decoder using time scaling synthesis. The synthesized PCM audio is used to remove or reduce the duration of transient prenoise, improving the perceived quality of low-bit rate audio coded transient material.
