Start at the very beginning
What sound is, how frequency becomes pitch, and why a wave's shape decides its character. No prior music theory needed, just curiosity and headphones.
Learning · A hands-on course in synthesis
Learn how synthesizers really work.
Aether Learn teaches you sound from the ground up, one hands-on lesson at a time. Every idea comes with a real synth engine you play with your finger, so you hear it the moment you read it.
SOUND & FREQUENCYWAVEFORMSFILTERSENVELOPESMODULATION
Five modules. From what sound is, to making sounds you understand.
Learn by playing
Read it, watch it, then play it yourself.
Every lesson has three steps: the idea in plain language, a short demo that moves the controls for you, then a real instrument you play. The waveform, harmonics, filter curve, and envelope all respond in real time as you turn the knobs.
◇
See a wave built from sines
Add pure sine waves one at a time and watch them stack into a bright saw, and hear the tone sharpen with every one. The idea behind every sound, made visible.
◆
Shape tone with filters
Sweep the cutoff, add resonance, and hear the classic filter sweep. A live, EQ-style curve shows exactly which harmonics you keep and which you carve away.
▲
Sculpt sound over time
Attack, hold, decay, sustain, release, and delay: the envelope that turns one raw tone into a pluck, a pad, or a stab. Watch the playhead ride the shape you draw.
∿
Add motion and movement
LFOs, vibrato, tremolo, and the rhythmic filter wobble at the heart of bass music. Point one modulator anywhere and hear the sound come alive.
