Pitch Ribbon
AI generated monophonic pitch analysis desk with a confidence plot, stable note extraction and MIDI sketch export.

Screenshots supplied by the seller.
Description
AI generated. Pitch Ribbon follows a single melodic source through time using an original YIN style difference analysis. Explore three generated examples or decode a local file.
Inspect frequency, nearest note, cents and confidence on a pitch ribbon. Choose the source channel, gate, confidence threshold, tuning reference and minimum note length. Stable rounded pitches become editable export candidates through segmentation controls.
Audition the original or a simple synthesized note sketch, and export a pitch frame CSV, note MIDI or analysis JSON. This is an analysis aid with documented octave and noise limits, not guaranteed polyphonic transcription.

Technologies
HTML, CSS, JavaScript, Web Audio API
Setup requirements
Open index.html or serve the folder with any static HTTP server. Use a deliberate play action to enable audio.
Dependencies and ongoing costs
No third party libraries, paid APIs or required services. A current Web Audio capable browser is required. Optional static hosting can be free.
Known limitations
Standalone browser analysis utility. Local files limited to 20 MB and 30 seconds, decoded at 44100 Hz. Analysis uses a downsampled 11025 Hz signal, 1024 sample frames and 256 sample hops over approximately 55 to 1200 Hz. Confidence is algorithmic, not a probability of correctness. Octave errors, missed attacks and merged repeated notes can occur. MIDI rounds stable notes and omits vibrato and pitch bends. Transpose affects sketch playback and MIDI rather than the source. Hosted file operations remain unverified.
