A noise removal apparatus is provided for removing noise from frames of digital audio data. The apparatus comprises an error detector and a decoder. The error detector detects whether or not there occurs an error in a coded audio data composed of the digital audio data. The decoder decodes the coded audio data, in which a window function is applied to the coded audio data, and results coming from the application of the window function to different coded audio data are mutually added. The coded audio data to be decoded is error-free coded audio data inputted immediately before the occurrence of the error when the error detector detects that there occurs the error in the coded data.
