uses Processing to visualize sound, perhaps for live performance. As sound is picked up on your computer's microphone, this sketch produces two rows of spectrogram-like marks before the slate is cleared to start again. You can think of this as a paint brush that uses different bands of the audio spectrum as hairs or bristles.

There's a folder in this repo called spectrogram. It contains the code used to make the visualization above.

1. Copy spectrogram into your Processing sketches folder. On a mac, this is typically ~/Documents/Processing
2. Open spectrogram in Processing.
3. Now make some sounds (like talking, yelling, singing) and see things appear and change on screen.

• This is tuned for input from a MacBookPro microphone.
• This visualization likes a noisy mic.
• You may need to tinker with the code to get results you like. If I were using this with a quiet mic like a SM7B, I'd probably amplify the measured signal by multiplying the value of spectrum[i] by some constant.

Thanks for your kind attention!
