Deliver Mind-Blowing Performances
DjMirror Pulse is DJ audio analysis software that reads BPM, musical key, and song structure in real time, giving your visuals something to react to.
🎵 Breakthrough Audio Analysis Technology for DJs & VJs
What We Do
Real-time BPM Detection
Industry-leading BPM detection with unparalleled accuracy. Analyzes audio streams in real-time to provide precise tempo information for perfect beat matching and synchronization.
Advanced Rhythm Analysis
Comprehensive rhythm and harmony analysis that goes beyond basic beat detection. Identifies complex rhythmic patterns and harmonic content for professional mixing.
Song Structure Detection
Automatically detects song structures including intro, chorus, build-up, bridge, verse, and outro. Perfect for creating dynamic sets and understanding track progression.

🎵 Advanced Song Structure Detection: Master Every Track’s Flow
Our advanced AI automatically identifies and categorizes different sections of any moment:
Intro / Verse
Opening section that sets the mood and Storytelling sections with vocals
Chorus
Main hook and most recognizable part
Build-up
Tension-building section before drop
Bridge / Outro
Transitional section for variety and Closing section that fades out
🎵 Smart Audio Event Detection: Never Miss a Beat or Drop
Beat Detection
Adaptive peak detection with adaptive thresholds and minimum peak distance constraints
