We plan to design a sound visualization model by using a pitch detector to detect pitch and output with musical notation on the screen. Furthermore, we are going to store the melody and mimic piano sound on chips.

1. Detect Pitch.

We plan to make a pitch detector in hardware to detect sound in real time at a 10k sampling rate, and a LED light to indicate when it is ON or OFF. An autocorrelation analysis, center clipping, infinite peak clipping will be used to build up the detector.

2. Output music notation in real time.

Once a note has been detected, it will show on the screen at the right position. The previous notes on the music notation will move right. It will look like flowing music. The screen will be connected on a black board with detector in which we could display the sound in real time.

3. Store the melody.

We are going to store the melody in pitch into registers for future replay.

4. Mimic instruments sound.

we will use instrument sounds package, like guitar, piano, and violin to replay the melody on arduino. The mimic will not be in real time and only for replay mode.

LED Cube

Featured Project

LED technology is more advanced and much more efficient than traditional incandescent light bulbs and as such our team decided we wanted to build a device related to LEDs. An LED cube is inherently aesthetically pleasing and ours will be capable of displaying 3D animations and lighting patterns with much increased complexity compared to any 2D display of comparable resolution. Environmental interaction will also be able to control the various lighting effects on the cube. Although our plan is for a visually pleasing cube, our implementation can easily be adapted for more practical applications such as displaying 3D models.
