Seam Engine Writes the Music Between Two Records

Field notes

The engine analyzes tempo grid, bar phase, key, band energy, and vocal separation before deciding where each record should leave or arrive. It then supplies a generative audio model with real audio on both sides of a hole and writes only that missing passage, testing several candidates for dead air and level continuity. The current build accepts MP3, AAC, WAV, and FLAC files up to 40 MB per record; larger stems are described as planned.
