Abstract
The conventional error conceal processing generates a greatly fluctuating irregular sound which is unpleasant to ears and causes a remarkable echo effect and click noise. A notification signal detection unit () judges processing for an input frame. In case of an error frame, a sound detection unit () makes judgment whether a preceding non-error data frame is a sound signal. If it is a sound frame, a sound copying unit () generates a replacing frame. If it is a non-sound frame, a transient signal detection unit () judges whether it is an attack signal by the transient signal detection and selects an appropriate area from the preceding non-error frame.
