DMX Music Visualization is software developed by SOH that uses the internationally patented LTCA (Light Technology Controlled by Audio) technology to control stage lighting directly by an audio signal. The program analyzes the audio input in real time and automatically generates a dynamic light show that corresponds with the music. It uses the industry-standard DMX512 protocol for fixture control.

LTCA (Light Technology Controlled by Audio) is an internationally patented technology developed by SOH for direct, centralized control of an entire lighting rig purely by an audio signal. The system operates fully autonomously without an operator, controlling dozens of lighting fixtures so that the light show incorporates artistic elements from the music. Unlike a human lighting operator, it reacts instantly to unpredictable changes in the music and enables non-stop live, dynamic lighting scenes.

• Fully autonomous operation without an operator
• Centralized control – individual lighting effects complement each other
• Light show corresponds with the music and incorporates artistic elements from the audio
• Significantly better utilization of lighting equipment
• Ability to individually control dozens of lighting effects simultaneously
• Non-stop live and dynamic creation of lighting scenes
• Fast reaction to unpredictable changes in the music
• Long-term reliable and trouble-free operation
