Sound Pixel Project NSF REU JULY 27TH, 2012
Building a Frame Design Concept Transportable, study, and easily constructed Material: 80/20 Lightweight aluminum alloy composite T-slot framing Speakers Original Concept: independent sound emitters In Use: six sets of stereo speakers Speaker Mounting Cable wiring and cable ties
Music Mixing Concept Enable multiple audio files to mix and create a unified track Default Track Signed 16-bit at a 44100 Hz Clipping Prevention Determines max sample value of the mixed track If the max surpasses the threshold the rest of the track is divided by the ratio of (max/threshold)
Networking Concept A client and server capable of streaming audio to individual speakers Streaming Each client manages a single speaker and is fed a raw audio stream Audio Playback ALSA captures data sent to virtual devices and packages it for soundcard playback
Conclusion The Sound Pixel Project is fully functioning All audio tracks must be pre-loaded into the server then sent to be played Future Projects: Real-time mixing Application interfaces to manage tracks Expanding the speaker grid Track motion with a Kinect
