First sound

This guide mirrors episode 01 of the series: osc -> out.

The goal is tiny on purpose: make one tone, then hear how pitch and waveform change it.

Step 1: Add oscillator

Section titled “Step 1: Add oscillator”

Press A O to add an osc node.

An oscillator is the simplest sound source in blzr.

Step 2: Add output

Section titled “Step 2: Add output”

Press A U to add an out node.

out is the final destination that sends signal to your speakers.

Step 3: Connect and activate audio

Section titled “Step 3: Connect and activate audio”

Connect osc.audio-out to out.audio-in.
Press Space Space in the out node to activate audio.

You should hear a tone immediately.

Step 4: Change pitch

Section titled “Step 4: Change pitch”

Move frequency on osc.

Lower values sound lower. Higher values sound higher.

Step 5: Change waveform

Section titled “Step 5: Change waveform”

Switch type between sine, square, sawtooth, and triangle.

You are still hearing one note, but the character of that note changes.

What you just built

Section titled “What you just built”

This is a patch: two nodes and one connection.

That simple graph is the base pattern for everything else in blzr.
