THE DATA

50 full-length vocal stem packs from Sonja.

One vocalist. Consistent microphone, consistent room, consistent quality across every take. No production artifacts. No bleed. Just the voice.

Each pack includes:

• Lead vocal (full performance)

• BGVs / Harmonies (isolated)

• Ad-libs (organized by take)

• Dry WAV stems — 44.1kHz / 24-bit

Everything organized by BPM + KEY + MODE.

Everything ready to feed your pipeline.

WHAT YOU CAN ACTUALLY DO WITH IT

Train voice conversion models. Test synthesis pipelines. Benchmark your timbral modeling. Debug why your model sounds great on read speech and garbage on sung vocals.

This is the data gap. Most open voice datasets are spoken word. Singing is a different problem — breath control, vibrato, pitch drift, consonant release timing. Your model learns on the right data or it learns the wrong thing.

This pack gives you over 150 minutes of the right data to find out which one you're building.

WHO THIS IS FOR

• Building a singing synthesis model

• Training a voice conversion pipeline

• Evaluating synthesis quality against real studio data

• Benchmarking a new audio pipeline before you ship it

THE CATCH

No catch. No form gate. No signup. No "We'll email the zip to you soon."

Just download it and build.

The only rule: don't redistribute the raw stems as a standalone pack. Use them for training, testing, and prototyping. What you build with them is yours.
