What is sound?

In blzr, sound is a signal changing over time.

The first thing to hear is a simple oscillator.

osc -> out

That patch gives you one continuous tone.

The three controls that matter first

• Frequency changes pitch. Low values sound low, high values sound high.
• Wave type changes tone color. A sine is smooth, a square is buzzy, a sawtooth is bright.
• Amplitude changes loudness. In practice, you usually control that with amp.

Why this matters

Episode 01 of the series starts here on purpose.

If you can hear pitch change and waveform change, you already understand the first layer of synthesis.

Everything after that is shaping, controlling, combining, or hiding this signal inside a larger patch.
