Hey Product Hunt! 👋 I'm the creator of Système D (STM-D), a free web application I built for sound technicians, live sound engineers, audio students, and anyone passionate about sound. I wanted to bring useful audio tools together in one place — from practical calculators and learning resources to measurement tools and a 3D stackbuilder for visualizing speaker configurations. The goal is simple: make everyday audio work easier and make useful tools accessible to everyone, without ads or paywalls. STM-D is an independent project, built out of a genuine passion for audio and a desire to create something useful for the community. I'm sharing it here to reach more people in the audio world, get honest feedback, and keep improving the platform. If you work with sound, I'd love for you to give it a try and tell me what you think! 🚀 Check it out: https://stm-d.com Thanks for checking it out!
