## What is SinOscillators?

SinOscillators is a strange synthesizer with nine oscillators. It uses a unique sine wave generation algorithm, resulting in sounds that are difficult to predict and control. Sometimes the sounds are noisy, sometimes eerie, but sometimes they're captivating enough to listen to for a long time.

This app allows you to set and control the following:

- Buffer: Size of audio buffer
- Transition: Parameter transition time
- Spread: Stereo sound spread
- Volume: Overall volume

- Shuffle: Randomly set oscillators to the same value
- Clusterize: Set the oscillators to similar values
- Harmonize: Adjust oscillators systematically
- Mute: Temporarily silence oscillators

- Slider: Set oscillator’s parameter lik a pitch
- Button: Play or stop oscillators

- Randomize: Randomly change parameters
- Targets: The percentage of random parameter changes
- Timer: Randomly change parameters at specified intervals
