Abstract: A method for encoding data, including processing the data one data window at a time, as follows: computing spectral components of data of a first frame of data using data from the one data window, selecting prominent spectral components of the data using a selection method appropriate for the data, and quantizing the prominent spectral components, thereby producing a frame of encoded data. A method for decoding data including frames of encoded data, by performing, for each frame, de-quantizing the frame of encoded data, thereby producing a frame of de-quantized encoded data, smoothing continuity of the de-quantized encoded data based, at least in part, on comparing values of the de-quantized encoded data with values of de-quantized encoded data of a prior frame, thereby producing a frame of smoothed data, and transforming the frame of smoothed data to a frame of time domain data. Related apparatus and methods are also described.
