Correction examples

This page asks a simple question: given a corrupted vocal over the original backing, which system recovers pitches that sound in tune with the band?

For every song you hear six mixes. The clean original mix comes first. Next is a GRU-detuned vocal only. Then comes detune plus global outshift. That third vocal is the shared input to MIDIBack, BERT-APC (GRU-only), and DDPC (Uniform). The last three clips are their corrected outputs mixed with the same original backing. Pitch edits use Praat TD-PSOLA via Parselmouth.
