We’ve published a preview of the Celtic Constellation Reference Sessions dataset: aligned multitrack recordings of traditional and contemporary Celtic ensemble arrangements.
The architecture is aligned pairs. Each piece exists as dry isolated stems, the same performance processed through a production chain, and the finished mix. The intent is that a model can learn the relationship between raw source material and produced output, rather than only seeing one or the other.
The preview includes two full mixed tracks and short paired stem excerpts from two instruments, pulled from the same time window so the alignment is audible. Full-length stems are not included in the preview.
Instruments in the series: Scottish Smallpipes, Highland Bagpipes, Irish Tin Whistle, Irish Low Whistle, Uilleann Pipes, Bodhrán.
Technical: 96 kHz capture, 24-bit WAV delivery, articulation-level metadata.
This sits alongside our Human Vocality Primitives series (17 categories, complete) and preview material for several other instrument traditions. Everything is rights-cleared and purpose-recorded — no scraped material, full performer consent, unencumbered rights.
Happy to answer questions about the capture methodology, metadata schema, or the aligned-pair structure.
