Press Play and watch the entire course replay as a self-playing audiovisual performance: sine, harmonics, square, organ, bell, envelopes, and a finale chord.
In the world
This is the test a working sound designer faces every day: here is a reference tone, now recreate it from scratch on whatever synth is in front of you.
Three target presets are loaded into the widget: an organ, a bell, and a vowel. Each has a spectral silhouette and a specific envelope profile. Pick one, study its shape, and rebuild it on the rack using everything from the course: mixer faders for the harmonic recipe, per-partial ADSRs for the decay profile, VCOs retuned for inharmonic content if the target is a bell.
When your spectrum mirror silhouette overlays the target within a visible tolerance, the patch is matched. Then move to the next target.
Did you know?
Jean-Claude Risset at Bell Labs in 1965 was the first person to resynthesize a trumpet from its Fourier analysis - partial by partial, envelope by envelope. Listeners could not tell the computer version from the recording. Every technique you learned in this course descends from that experiment.
Explore
A spectral aurora fills the sky. This is a self-playing 45-second journey through the sounds you built during the course - organ tones, bells, vowels, piano strikes, tremolo sweeps. The camera flies through shimmering aurora ribbons as each sound paints the sky with its harmonic signature. Sit back and watch your course come alive.
