This is fantastic. I love how it makes Earth’s rotation feel immediate and visceral with zero equipment. The controls and overlays are really well thought out. It would be cool to …

This grew out of a project called Myovine — a BLE EMG armband that streams 2 kHz × 8 channels to a mobile app for real-time muscle activity analysis. The signal processing ran on L…

Who It’s For • Node backends running streaming DSP • Systems needing stateful pipelines + fault tolerance • Teams avoiding separate Python/C++ services • IoT gateways w/ intermitte…

Code Example: const pipeline = await createDspPipeline({ redisHost: "localhost", redisPort: 6379, stateKey: "dsp:user:ch1", }); pipeline .filter({type:"butterworth",mode:"bandpass"…

DSP Primitives: • STFT, Mel-spectrogram, MFCC • FIR/IIR (Butterworth, Chebyshev, Parks-McClellan) • Time + FFT convolution • Decimation, resampling, rectification • Hilbert transfo…

I built dspx after hitting a wall with real-time EMG processing in Node.js. Problem: 2 kHz × 8 channels → filters → decimation → FFT. JS is too slow; the Python sidecar is complex;…
