Fretiq: Browser-Native Electric Guitar String Classification via Engineered Spectral Features and Held-Out Free-Play Evaluation

תקציר מקורי באנגליתarXiv:2607.18303v1 Announce Type: cross Abstract: Identifying which string produces a given pitch in monophonic electric guitar audio is a fundamental classification challenge: a single pitch can often be produced on multiple strings at different fret positions, with timbral differences that prior listening studies confirm are largely imperceptible to untrained humans. Existing approaches using support vector machines and spectral envelope features have achieved F-measures of 0.90 for six-string electric guitar classification, while String-Inverse Frequency features in earlier work achieved F1 scores up to 0.72. We present Fretiq, a preliminary single-instrument, single-player browser-based string classification system built on a 26-dimensional feature representation integrating frequency
