YOUR WORDS SHAPE THE SOUND
Warm.

you want to hear.
Start with a favorite artist or band, a pedal you love, or an idea that takes a paragraph to explain. You don’t have to know how to code it.
THE IDEAGenerated in 6.8 seconds
“A warm echo with repeats that slowly drift away.”
Read the full prompt
A warm echo with repeats that slowly drift away. Give me Time, Repeats, Tone, Depth, Rate and Mix controls, and a Drift toggle. Keep the dry guitar clear and the echoes soft and musical.
Afterglow
A little movement behind the notes. Space to let them breathe.

Afterglow, with shorter repeats and the same warmth. One follow-up keeps the idea moving.

Make the repeats shorter.”
An actual follow-up to Afterglow. The player above compares both versions.

A few things worth knowing.
Do I need to know how to code?
No. Describe the sound you want in ordinary language. You can audition it and ask for changes in Studio. Advanced mode exposes the generated FAUST code if you want to work with it directly.
Do I need Stratus to try FX Builder?
You can build and audition effects in the browser with an audio file or compatible live input. To take those effects onto a physical pedal, install them on Stratus through the Chaos Audio app.
Do I need a subscription to keep my effects?
No ongoing subscription is required to keep playing effects you have created and installed. Creating or refining effects uses Builds; available allowances and optional plans are explained inside FX Builder.
Can I start with an artist, band or pedal?
Yes. Name an inspiration and describe the qualities you like, or write a completely original idea. Results are original AI-generated interpretations—not promises of identical recordings, circuits, or artist endorsements.
How fast does it work?
The examples here took about 7 to 89 seconds to generate in our 2.0 session. The full 255-word Paper Satellites brief took 16.1 seconds. Those are recorded generation times, not guarantees; loading, compilation and installation can add time. Complex ideas can benefit from a few refinements.
How were these audio examples made?
Each effect was generated in the actual FX Builder 2.0 app from the full prompt shown here. The same licensed guitar performance was processed through that effect’s FAUST code, using the app’s compiler technology. These are software-rendered examples, not recordings through physical Stratus. Playback comparisons are loudness-matched; echo and reverb tails are included.
Guitar: “clean guitar loop.wav” by mil_dew, released under CC0. A four-bar phrase is used with silence for effect tails. Original performances are not recordings of the referenced artists.
