AN ADAPTIVE TIME/FREQUENCY-BASED AUDIO ENCODING METHOD

摘要

The invention proposes an enhanced adaptive time/frequency-based audio encoding method for encoding an input signal into an output data stream that allows a high efficiencyencoding at a high audio or speech quality. The invention proposes selecting the time-basedencoding mode or thefrequency-based encoding mode for therespective frequency-domain signalofthe plurality of the frequency-domain signals pertaining to the input signalbased on a peakednessofsaid respective frequency-domain signal.
