Abstract

Edit 28/09/2015 The invention provides an audio encoder for encoding the audio signal (AS) to cause The encoded signal (ES) from that audio signal. Audio encoder (1) that includes A framing device (2) that has been built into a configuration to extract the frame (F) from the audio signal (AS), the quantizer (3) that has been built into the configuration to map. The spectral line (SL1-32) of the resulting spectral signal (SPS) is formed from the frame (F) of the audio signal (AS) to the quantisation index (I0, I1), where the The tie (3) has a dead zone (DZ) wherein the input spectral line (SL) is mapped to the zero quantison index (I0) and the control device (4) that is generated. Up in the dead zone (DZ) configuration, where the control device (4) is comprised of a sound system computation device (5) built into the configuration to calculate at least one indication value. Audio system (TI5-32) for at least one spectral line (SL1-32) or for at least one group of spectral lines (SL1-32) where the control devices (4) are built into the configuration.
