RSS: Surround Sound Over Radio, No Wires

Outcome: Lorem ipsum dolor sit amet: a wireless multi channel audio system that transmits discrete surround channels over RF to independent speaker nodes. I designed the transmission chain end to end, consectetur adipiscing elit, sed do eiusmod tempor.

What I Did

  • Designed the RF transmission architecture and channel allocation.
  • Built transmitter and receiver hardware, sed do eiusmod tempor incididunt.
  • Implemented the audio pipeline: encoding, sync, and playback.
  • Measured latency, range, and channel separation against targets.

Motivation

Lorem ipsum dolor sit amet, consectetur adipiscing elit: surround sound normally means running speaker wire across a room. The objective was a system where each speaker only needs power. Constraints: budget, latency ceiling for lip sync, and FCC legal transmission bands.

Results

Lorem ipsum dolor sit amet, consectetur adipiscing elit, measured performance vs. the original objective: latency, range, audio quality. Quis autem vel eum iure reprehenderit qui in ea voluptate velit esse quam nihil molestiae, and what the next revision would change.

Technical Details

Lorem ipsum dolor sit amet: modulation scheme, carrier frequencies, codec and bit rate, sync strategy across nodes, sed do eiusmod tempor incididunt ut labore.
