FIELD: radio engineering, communication.
SUBSTANCE: windower for applying a prediction coding analysis window to a stream of audio samples to obtain windowed data for prediction analysis and for applying a transform coding analysis window to the stream of audio samples to obtain windowed data for transform analysis. The transform coding analysis window is associated with audio samples within a current frame of audio samples and with audio samples of a predefined portion of a future frame of audio samples which is a transform-coding look-ahead portion. The prediction coding analysis window is associated with the portion of the audio samples of the current frame and with audio samples of a predefined portion of the future frame which is a prediction coding look-ahead portion.
EFFECT: high quality of the encoded audio signal.
