A new method to enhance the error concealment of single AAC frame loss is presented. This scheme exploits the time-domain aliasing cancellation property of the MDCT-based audio coder. A mean square error improvement of approximately 10 dB is achieved. The advantage of this method over the frame repetition technique that has the same computational weight is highlighted.
