In multichannel audio coding, an improved coding efficiency is achieved by the following measure: the noise filling of zero-quantized scale factor bands is performed using noise filling sources other than artificially generated noise or spectral replica. In particular, the coding efficiency in multichannel audio coding may be rendered more efficient by performing the noise filling based on noise generated using spectral lines from a previous frame of, or a different channel of the current frame of, the multichannel audio signal.

A method to process narrowband signals includes dividing the signal into segments of length N, where N optimizes filter bandwidth, FFT size, processing and memory. Each N-length segment is processed sequentially by filtering, a FFT and a peak detector that identifies the N-length segment's K largest spectral components. The frequency, bandwidth and power for the K largest spectral components are stored sequentially as N-processed data. After processing multiple N-length segments, reconstructing individual frequency spectrums for J continuous segments of the N-processed data, mapping the J reconstructed spectrums to a single spectrum, and applying the peak detector to the composite spectrum to separately store the single spectrum's K largest frequencies, with powers and bandwidths, as (N×J)-processed data. The N-length data is processed in groups of J until all N-length data is reprocessed. J may have multiple values, generating multiple processed data sets.
