Optimum quantizer design for pre-echo control in a low bit rate audio coding system
In a low bit-rate audio transform coding system, the quantization noise is spread out over the entire analysis block in the time domain after the inverse transformation in the decoder. This increases the likelihood of pre-echoes occurring prior to a transient event. In order to control preechoes...
