To better show what the device can do and how it feels like, I spent the past week developing a web-based simulator using Emscripten. It runs the stock firmware with most features available except for networking. Check it out and let me know what you think! The firmware will be open-source and available…

This has been a pet project of mine for the past ~5 months. It consists of six visualizations: - Spectrogram: Implements the reassignment method for sharper time and frequency resolution. - Spectrum analyzer: A-weighted, frequency guidelines, loudest frequency tooltip. - Waveform: Colored based on frequency, loudness, or static - Oscilloscope: Tracks pitch and autocorrelates against a reference signal, provides stability. Also includes a regular zero-crossing trigger. - Stereometer & Phase meter: Linear and exponential scaling modes, adjustable windows. Multi-band correlation meter. -…
