Show HN: Veena Chromatic Tuner

Summary

Veena Chromatic Tuner lets you to tune in Equal Temperament/Just Intonation with oscilloscope-like stable waveform display. This powerful, versatile tuning application is designed for musicians who need precise control over their instrument tuning across multiple musical traditions (Equal Temperament, Just Intonation). It displays the pitch (frequency) and deviation in cents via a needle interface. A unique visual feature is its linear and circular waveform display of input audio: the waveform appears stabilised when in tune with reference note selected, rotates right when sharp, and rotates left when flat, providing immediate visual feedback for precise adjustments. This dynamic visual feedback, akin to a digital oscilloscope's trigger synchronisation, offers immediate and precise adjustment cues.A Veena instrument mode has been added, allowing users to play and tune notes across 24 fret positions. This feature is particularly useful for instrument makers. When choosing Just Intonation or Carnatic tuning profiles, fret positions are based on specific ratios. Consequently, this mode allows you to observe how note positions on the first and other strings vary relative to each other when pure intonation is applied.
