Perancangan alat antrian suara (CD)
The application of recording and voice playback have already by people nowadays. Some people use the specified voices integrated circuit, otherwise there is a lack such as: we could not select the specified trackof the recording.
In this research, the EEPROM had filled with sound file like *.wav file. To playback the voice recorded in the EEPROM, we used microcontroller and R-2R DAC ( Digital to Analog Converter).
Voice was recorder in the PCM format, 11 Kbyte/sec. the result that voice could be playback normally. Eery microcontroller programmers could try to add or sometimes substract the number of sampling rate to produce the experimentd sound. That’s why in this research, microcontroller and sound theory had beeb elaborated
