|43||Real-Time Sound Visualization
|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.
