OtsAV DJ
OtsAV DJ is a professional DJ automation and live mixing software developed by Ots Labs in Australia. It combines traditional DJ mixing capabilities with powerful automation features, making it suitable for both live performance and unattended music playback in commercial environments like bars, restaurants, retail stores, and radio stations.
The software features a dual-deck mixing interface with waveform displays, crossfader, per-channel EQ and volume controls, and beat detection for manual and assisted mixing. The visual interface is functional and information-dense, prioritizing utility over aesthetics. Audio quality is high, with professional-grade processing and support for various output configurations.
OtsAV's automation capabilities are its primary differentiator. The OtsAutoMix system can run entire music programs unattended, with intelligent track selection, beat-matched transitions, and scheduling. DJs can pre-program music rotations based on time of day, day of week, genre rules, and energy curves. This makes OtsAV popular in commercial installations where consistent, professional-quality background music is needed without a live DJ.
The software includes video mixing support for music video DJ sets, with video output to external displays and support for various video formats. Karaoke features handle CDG format playback with lyric display and singer management. Internet broadcasting capabilities enable streaming to online radio stations via Shoutcast and Icecast protocols.
OtsAV supports MIDI controllers for hardware integration, multiple audio outputs for headphone cueing, and plugin architecture for extended functionality. The software's commercial licensing model is designed for business use, with editions tailored to different professional scenarios (DJ, Radio, TV). While OtsAV may not have the brand recognition of Serato or rekordbox in the performance DJ market, it has carved out a reliable niche in commercial audio installations and automated DJ scenarios where uptime and consistency are critical.
