wavtomid chung is a high-quality polyphonic audio-to-MIDI converter designed to transform WAV and MP3 files into accurate MIDI files. Developed with free and open-source tools, it offers precise transcription suitable for piano recordings and similar instruments. The converter utilizes a refined algorithm that approaches the quality of original audio, ensuring detailed note detection and timing accuracy.

The software incorporates a spectrum filter to enhance audio detection and reduce the impact of reverb and self-harmonics, improving the clarity of the MIDI output. While it performs best with well-tuned piano recordings, it has shown promising results with pieces by artists like Bill Evans and Finanwen. It is specifically optimized for instrumental tracks and is not suitable for vocals or drum recordings.

wavtomid chung also supports importing MIDI files and allows users to apply a 'wavtomid-like' effect to existing MIDI sequences by exporting the processed output as new MIDI files. This feature expands creative possibilities for musicians and producers seeking to enhance or manipulate MIDI data derived from audio sources.
