Designed MP3 encoder using ARM processor
Wireless audio processor with ADPCM




In this works, we implemented the digital audio transmitter and receiver module for wireless microphone. For digital audio realization, we studied MPEG-I Layer III format and implemented real time encoder using DSP. And we developed real time encoder based on ADPCM also. To communicate via wireless channel, we adopted DS-Spread spectrum technology and implemented using AIM chipset.
