PyTorch port of CREPE (Kim et al., ICASSP 2018) — deep CNN for monophonic pitch estimation. 360 pitch bins covering C1-B7 with 20-cent resolution. Model capacity options from tiny to full. Near-perfect accuracy on clean monophonic signals. GitHub: maxrmorrison/torchcrepe (516 stars). Install: pip install torchcrepe.

Relevance

Essential for banjo solo pitch tracking. Banjo is primarily monophonic — CREPE provides highly accurate F0 contours. Combine with onset detection for note-level transcription. Latest alternative: PESTO (2025, self-supervised, faster).
