According to an embodiment of the invention there is provided a method for multi-rate encoding in a communication system. The method comprises the step of providing a codec with sets of tuning parameters for use in selection of codec modes. Each set of tuning parameters provides an average bit rate. A bit rate target is received for encoding a signal by the codec, the bit rate target having any value between the minimum and maximum average bit rate of the codec. An encoding mode is then selected based on the bit rate target and the sets of tuning parameters, and the signal is encoded by means of the selected encoding mode. A multi-rate codec comprising a selector for selecting an encoding mode from a set of encoding modes based on a bit rate target is also provided. <IMAGE> |
