Audio analysis
Every analysis detects four core metrics simultaneously:
BPM
Tempo (beats per minute)
90–94%
174
Key
Musical key + relative key
91–94%
F# minor ↔ A Major
Tuning (Hz)
A4 reference frequency
94–97%
432.0 Hz
Loudness (LUFS)
Integrated loudness (EBU R128) + Loudness Range
Broadcast-standard
-8.5 dB LUFS / LRA 8.3 LU
Each metric includes a confidence score (0–100%) so you know how certain the result is.
Visual Report Card
Every analysis generates a cinematic report card image optimized for sharing:
Track name, BPM, Key (with relative key), Tuning, Loudness
Color-coded confidence indicator
Dark, high-contrast design readable on any screen
Tagged MP3
The bot returns a clean MP3 file with ID3 tags:
Title — cleaned track name
BPM — detected tempo
Key — musical key in standard notation
Comment — tuning frequency, loudness, and analysis metadata
Drop it straight into your DAW, DJ software, or music library — everything is tagged.
