Audio Pitch Tool

The tool analyzes uploaded audio to extract pitch over time, solving the need for objective pitch data in music workflows. It accepts common audio formats and returns a time-aligned pitch track, including frequency in Hz, musical note, MIDI number, and a confidence score. Conceptually, it segments the audio into frames and estimates the fundamental frequency for each frame using robust DSP algorithms, then maps frequency to musical notes using standard 12-TET. The results enable musicians to verify tuning, transcribe melodies, and perform quality checks in production or education. Beneficiaries include performers, teachers, studio engineers, and QA staff who require repeatable pitch data across sessions. Unique value lies in explicit per-frame pitch with confidence, exportable formats, and batch processing for multiple files. Core features include support for multiple analysis methods (YIN, autocorrelation, FFT), frame and hop size configuration, and JSON/CSV exports for downstream tools. Use cases span tuning verification, melody transcription, competition or audition QC, and classroom demonstrations of pitch stability.
