Abstract
A system and method of the present invention conceal errors caused by lost audio in an audio transmission. A frame error detector detects audio data lost in an audio data transmission. An audio decoder generates frequency and time domain data from received audio data. A transient detector detects the presence of a transient audio signal in the received audio data. A frame synthesizer interpolates frequency domain data to generate synthetic audio data to construct audio data in place of the lost audio data.
