Veena Chromatic Tuner▲53
We're happy to present Veena Chromatic Tuner, an app we've developed for musicians, instrument makers, and ethnomusicologists who need more than just a standard chromatic tuner. Our goal was to create a tool that not only supports pitch detection but also provides deep support for diverse musical intonation systems and offers intuitive visual feedback. The Problem We're Solving: Many tuners are good for Equal Temperament, but has limited support when it comes to the Just Intonation, microtonal music, or the specific requirements of instruments like the Veena where fret positions are…

OpenMeters – A fast and free audio metering/visualization suite▲16
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. -…

Voice Composer – Browser-based pitch detection to MIDI/strudel/tidal▲32
Built this over the weekend to bridge the gap between "can hum a melody" and "can code algorithmic music patterns" (Strudel/TidalCycles) for live coding and live dj'ing. What it does: Real-time pitch detection in browser using multiple algorithms: CREPE (deep learning model via TensorFlow.js) YIN (autocorrelation-based fundamental frequency estimation) FFT with harmonic product spectrum AMDF (average magnitude difference function) Outputs: visual piano roll, MIDI files, Strudel/TidalCycles code All client-side, nothing leaves your machine Why multiple algorithms: Different pitch…
