I have waited my entire life for this product.

Built this over the weekend to bridge the gap between &quot;can hum a melody&quot; and &quot;can code algorithmic music patterns&quot; (Strudel&#x2F;TidalCycles) for live coding and live dj&#x27;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&#x2F;TidalCycles code
All client-side, nothing leaves your machine
Why multiple algorithms:
Different pitch detection approaches work better for different inputs. CREPE is most accurate but computationally expensive; YIN is fast and works well for clean monophonic input; FFT&#x2F;HPS handles harmonic-rich sounds; AMDF is lightweight. Let users switch based on their use case.Technical details:React, runs entirely in browser via Web Audio API
Canvas-based visualization with real-time waveform renderingThe original problem: I wanted to learn live coding but had zero music theory. This makes it trivial to capture melodic ideas and immediately use them in pattern-based music systems.Try it: <a href="https:&#x2F;&#x2F;dioptre.github.io&#x2F;tidal&#x2F;" rel="nofollow">https:&#x2F;&#x2F;dioptre.github.io&#x2F;tidal&#x2F;</a>Works best on desktop. Will work more like a Digital Audio Workbench (DAW).Source: <a href="https:&#x2F;&#x2F;github.com&#x2F;dioptre&#x2F;tidal" rel="nofollow">https:&#x2F;&#x2F;github.com&#x2F;dioptre&#x2F;tidal</a>
