WaivOps Lo-Fi Chords Dataset For Music ML

Lo-Fi Chords is an open dataset of 8,000 stereo WAV loops with paired JSON metadata, featuring chord progressions inspired by retro soul and vintage library music. The audio was generated from a large set of MIDI patterns using multi-sampled acoustic, electric, and synth-piano instruments. Data augmentation included humanization, time shifting, filtering, EQ, tape/vinyl noise, and convolution reverb modeling to create varied piano tones and ambient effects for training generative audio models.
