StarMP3/AAC

StarMP3/AAC - 2 channel Digital Audio Decoder StarMP3/AAC is a single-chip digital audio decoder, capable of decoding ISO/IEC 11172-3 Layer III(MP3)audio format and ISO/IEC 13818-7(AAC) audio format.

StarMP3/AAC receivers the input bit stream through a serial data nterface. The decoded signal is 16-bit serial PCM format that can be sent directly to DAC. The off-chip DAC Interface is programmable to adapt the PCM putput of StarMP3/AAC to the most common DACs used on the market.

An 8-bit host interface port is provided to receive control information from and send tatus information to host. 8-bit microcontrollers such as those of Intel or Motorola can be connected easily.

StarMP3/AAC has the capabilty of compressing voice signals. It can receive voice signals through ADC. The compressed voice signal is transmitted to or received from host through serial data interface. It can also reproduce the voice signal from the compressed voice signal.
