| Abstract: | ISD4004 voice recording and playing chip are widely used in many areas, but there are many problems in the process of voice recorder to chip. This article briefly describes the characteristics of the series of chips and how it works and then puts forward by PC audio output interface and RS232 serial interface, combined with a single-chip ISD4000 series recording a voice chip bulk after all kinds of audio signals, and allows any section of the audio output. |
