A sound design studio for the generative era

Build sound stacks
from prompts, scenes
and images.

Phonostack helps creators turn scenes, images, prompts and sonic ideas into structured sound stacks: generated sounds, music layers, voices, prompt cards, variations, metadata and export-ready files.

Compose sound the way a designer thinks.

How it works

What if your prompt box could build a whole sound stack?

Design labs — specialized environments for every sound family

Each lab is tuned for a specific family of sounds: Foley, atmosphere, creature, human, vehicle, texture, UI, music and more. Same prompt language, same library, different vocabulary and controls.

Tools — workflows that extend every sound stack

Built with ElevenLabs.

Phonostack integrates ElevenLabs sound effects, voices, dialogue, music and related audio tools into a unified workflow for generative sound design.
