Best for
- Karaoke and Practice Tracks: Remove or isolate vocals to create karaoke versions or instrumental practice tracks for musicians and singers.
- Remixing and Production: Extract individual instrument stems (drums, bass, guitars, piano, synths) for remixing, re-arranging or creating stems-based productions.
- Post-Production for Video: Isolate or remove background music and vocals from video soundtracks for editing, dubbing, or sound design.
- Sampling and Sound Design: Isolate clean instrument or vocal samples for sampling, sound design, or reprocessing in a DAW.
- Music Education and Analysis: Separate parts to analyze arrangements, chordal structure, or individual performances for learning and transcription.
- Platform Integration: Embed stem-splitting via API in apps, services or websites to offer automated audio separation to end users or clients.
- Removing or isolating vocals for karaoke, remixing, or sampling
- Extracting individual instrument stems for mixing, mastering, and production
- Integrating stem-splitting into third-party websites, apps or services via business/API solutions
- Batch or automated workflows using community scripts (Python/Colab) to download and merge segments
- Audio-forensics or speech/music separation for research and post-production
PHBench
Vela Partners
A benchmark dataset and evaluation suite mapping Product Hunt launches to Series A outcomes for predictive modeling of startup funding.
Key features
- Large-Scale Mapping: Links 67,292 featured Product Hunt posts to 528 verified Series A outcomes within an 18-month horizon, enabling longitudinal outcome prediction.
- Engineered Signal Set: Provides 61 engineered features per post including engagement signals (votes, comments, reviews), rank signals (daily/weekly/monthly), maker features (maker count, followers), temporal features, topic flags, and interaction terms to support rich modeling.
- Structured Splits and Imbalanced Labels: Published train/validation/test splits (Train: 47,071; Val: 6,753; Test: 13,468) with measured positive rates (~0.76–0.79%), plus withheld test labels for blind benchmark evaluation.
- Evaluation & Submission Workflow: Test labels are withheld and researchers submit predictions (email to benchmark@vela.partners) for centralized scoring to enable fair comparison between models.
- Open License & Citation: Distributed under CC BY 4.0 (per Hugging Face dataset page) with a required citation (Ihlamur et al., PHBench arXiv 2026) for academic and research use.
- Supporting Code & Graph Tools: Associated code and GNN/graph-analysis workflows are available (Weave project on GitHub) to build graph representations and run node-classification experiments; dataset access may require contacting Vela Partners due to access conditions.
- Mapped dataset of 67,292 Product Hunt featured posts linked to 528 verified Series A outcomes (18-month horizon, 2019–2025).
- 61 engineered features per post: engagement signals (votes, comments, reviews), rank signals (daily, weekly, monthly), maker features (maker count, followers), temporal features, topic flags, and interaction terms.
- Standard train/validation/test splits with class imbalance details (Train: 47,071 posts, 372 positives; Val: 6,753 posts, 53 positives; Test: 13,468 posts, test labels withheld).
- Withheld test labels and centralized scoring: submit predictions to benchmark@vela.partners for evaluation.
- Hosted on Hugging Face Datasets with CC-BY-4.0 license; access requires agreeing to share contact information.
- Suitable for benchmarking binary classification models, feature-ablation studies, imbalanced learning experiments, and startup outcome research.
- Tabular data format compatible with common ML tooling (Hugging Face Datasets, pandas, scikit-learn, PyTorch, TensorFlow).
