Built by a DJ, for DJs
Crescendo was created by a veteran DJ with over 30 years of experience to solve one problem: preparing better DJ sets faster. Whether you are a professional mobile DJ, wedding DJ, club performer, or just learning how to mix music, this app provides powerful playlist building tools that save hours of gig preparation. Unlike traditional DJ mixing software, Crescendo focuses entirely on planning and structuring your music library before you hit the stage.

Key Features
Harmonic Mixing & Key Detection: Deeply analyze every audio track and organize your music library using the Camelot Wheel. Crescendo detects musical keys automatically so you can build harmonic DJ playlists with smooth transitions and professional-sounding mixes.

On-Device AI Playlist Builder: Simply describe the vibe you want. Prompt the intelligent music assistant to generate a "2-hour house set in the style of James Hype," a "deep warm-up playlist," or "peak-time techno." Powered locally by Gemini Nano on supported devices—your music data never leaves your phone.

Voice Commands: Speak directly to the app to instantly curate a custom track selection based on mood, tempo, or style.

Advanced Music Filters: Sort your audio files in seconds using fast filters for BPM, Camelot Key, genre, energy level, track rating, and artist.

Smart Transitions: Save your favorite track combinations. The intelligent engine remembers your preferred song blends and automatically suggests those transitions for future gig playlists.

Wireless Wi-Fi Music Transfer: Effortlessly drag and drop audio files from your computer browser straight to your Android device over Wi-Fi. No cables or cloud storage subscriptions required.
