## What is Underground Club?

Underground Club turns your iPhone into a compact sound laboratory, allowing you to experiment, explore and create your own audio textures without limits.

This app lets you synthesize sound waves, combine them into effects chains, and explore how different settings change the sound. Feel free to experiment with everything from simple timbres to complex sonic structures using tools such as oscillators, filters, and modulation.

Built-in visualization features allow you to check the shape and spectrum of the sound in real time, allowing you to customize the sound intuitively and easily. Test out different presets, create your own combinations, and change parameters to see how the sound changes.

All features work completely offline, requiring no internet connection, subscription or access to your personal data. This makes Underground Club a convenient space for creativity, experimentation and sound exploration.

Underground Club is a portable sound design studio in your pocket, anytime, anywhere.
