    The recent technology of the television is implementation the digital system over transmitter, transmission channel and receiver. Therefore, television system in Indonesia is dominated by analog system, that less flexible for system development and communication on digital communication system. So that, it need actions to develop the digital broadcasting system to replace the analog broadcasting system. Audio signal information with high quality would help the television audience to increase the perception of the information displayed. Transmission channel capacity will become limited, while the need of channel communication is increased. The limited channel capacity endorse to save all aspect on the telecommunication system. There are some research on audio signal coding to obtain the lower bit rate for transmission channel usage saving. The audio signal is processed, so that the redundant component can be decreased, then we obtain the simple size of information that reliable to be transmitted. The research aim is coding the audio signal on the low bit rate for saving the channel communication usage for digital television broadcasting. The research will be done is develop an audio signal coder on the low bit rate with the suitable decoder. The decoder consists of the parameters detector, signal synthesizer, and the periodic signal generator. The encoder and the decoder development is implemented using C++ software. The hardware for the simulation process consists of microphone, digital signal processor and the personal computer equiped with sound card for audio signal acquisition.
