GreenGo uses ultra high-precision BPM detection with multiple analysis methods including IOI histogram analysis and beat interval tracking with weighted consensus. It applies integer BPM snapping to common production tempos, a high-pass filter at 60 Hz to remove sub-bass interference, and beat phase coherence verification. The BPM range is 70–200, covering all major DJ genres from hip-hop to drum & bass.
GreenGo uses a multi-signal fusion key detection engine with genre-aware parameter profiles. It combines four independent methods: libKeyFinder DLL analysis, librosa chroma ensemble (CQT + CENS + STFT), STFT-only chroma analysis, and sub-bass root detection for EDM tonic confirmation. Results are output in both Camelot notation (Rekordbox, Serato, VirtualDJ) and Open Key notation (Traktor).
Camelot notation is a simplified key labeling system used by DJs for harmonic mixing. Each musical key gets a number (1–12) and a letter (A for minor, B for major). For example, A minor = 8A, C major = 8B. Keys adjacent on the Camelot wheel (same number or ±1) sound good when mixed together. GreenGo outputs both Camelot and Open Key notation automatically.
Yes. GreenGo includes a vibe detection engine powered by machine learning RandomForest and XGBoost models trained on over 14,000 tracks. It detects energy (1–10), danceability (1–10), and mood labels including Aggressive, Intense, Euphoric, Dark, Neutral, Happy, Melancholic, Chill, and Romantic. Mood detection uses genre-aware probability weighting for improved accuracy.
Yes. GreenGo supports batch processing with configurable parallel workers (1–8 threads). Paste multiple URLs at once for batch downloading, or select an entire folder of local files for batch BPM, key, and mood analysis. All results are automatically written to ID3 tags.
Yes. GreenGo writes BPM, musical key (Camelot and Open Key), title, artist, and genre directly into ID3 tags (TBPM, TKEY, TXXX:INITIALKEY, TXXX:OPENKEY). These tags are automatically recognized by Rekordbox, Serato DJ, Traktor, VirtualDJ, and any other DJ software that reads standard ID3 metadata.
GreenGo supports MP3, WAV, AAC, FLAC, M4A, and OGG. Audio quality options include 128kbps, 192kbps, 256kbps, and 320kbps. BPM and key detection works on all supported formats.
GreenGo can capture audio from 10+ supported YouTubes. Capture is built directly into the GreenGo browser — supported pages get a one-click capture button as you browse, with no separate extension to install.
Mixed In Key ($58 one-time) focuses on key and BPM analysis of local files. GreenGo (from $5.99/month) is a complete browser-based pipeline — capture audio as you browse, split stems, detect BPM and key, detect mood and energy, write ID3 metadata, convert formats, and map your library automatically. Subscription with a 7-day free trial.
Tunebat is a free online BPM and key finder that analyzes uploaded audio files in your browser. GreenGo is a desktop application that handles the entire workflow downloading from URLs, batch BPM and key detection, mood analysis, ID3 metadata tagging, format conversion, and library organization. GreenGo processes files locally with multi-algorithm fusion for higher accuracy and writes results directly into your audio files.
No. Capture is built directly into the GreenGo browser. On supported audio pages, a one-click capture button appears automatically as you browse — tracks are queued straight into GreenGo for stem separation, BPM & key analysis, and tagging. Everything stays on your computer — no remote servers, no tracking.
Yes. GreenGo is a subscription with a 7-day free trial. Plans are Monthly ($5.99/mo), 3 Months ($15.99), or Yearly ($60). Subscriptions renew automatically and can be cancelled anytime from your account.
