A communication system that includes multiple conferencing devices connected in a daisy-chain configuration is communicably connected to far-end conference participants. Multiple conferencing devices provide improved sound quality to the far-end participants by reducing aural artifacts resulting from reverberation and echo. The daisy-chain communication system also reduces the processing and transmission time of the near-end audio signal by processing and transmitting the audio signal in frequency domain. Each conferencing device in the daisy chain performs signal conditioning on its audio signal before transmitting it in the frequency domain to a mixer. The output signal of the mixer is converted back to the time domain before being transmitted to the far-end. The daisy-chain configuration also provides a distributed bridge to external communication devices that can be connected to each conferencing device.
