Sound and listening systems for the agentic era.
An ecosystem of tools for designing, listening, generating, organizing, sculpting, and automating sound — across creative and computational workflows.

/ Mission
PositionPhonostack builds infrastructure for sound in a world where computation listens, speaks, generates, edits, organizes, and performs.
Sound is no longer made only by hands. It is now also generated, interpreted, organized, and transformed by humans, agents, models, and machines. We build the tools that hold this new reality together.

05/ Principles
04- 01Sound is infrastructure.Not a feature, not an asset. The substrate on which agents, models, and humans now act.
- 02Listening precedes generation.A system that cannot listen cannot decide. We treat audition as a first-class capability.
- 03Material before performance.Sound is matter. Granular, spectral, plastic. Tools should expose its interior, not just play it back.
- 04Memory over output.Every generation, prompt, and gesture is held. The library is alive, navigable, and shared.
