    Abstract: A conference system for independently adjusting audio parameters is provided, including a microphone module, a storage module, a digital signal processing module and an amplifier. When any microphone of the microphone module generates an audio signal transmitted to the digital signal processing module, the priority controller determines the priority order of the audio signals entering the digital signal processing module, the digital signal processing module will read the corresponding adjustment parameters stored in the storage module, and the volume controller, equalizer, feedback suppressor perform adjustment on the audio signal. Finally, the mixer mixes the audio signals and outputs to the amplifier. The amplifier amplifies the mixed audio signal and outputs to speakers. In this manner, a single digital signal processing module can adjust different audio signals from different microphones based on different adjustment parameters, without affecting the audio signal from other microphones.
