ROI Calculation Logic

This technology could achieve annual production cost savings of approximately $100K (AI est.) per facility in video content production. This is estimated by automating up to 20% of audio mixing tasks performed by skilled engineers, equivalent to reducing the workload of approximately 2 full-time skilled engineers (at an average annual labor cost of ~$50K/person (AI est.)), combined with resource optimization from reduced overall production time.

Speed to Market
6× faster than in-house development
The core audio processing algorithm is thoroughly disclosed in the patent specification, indicating high technical feasibility. Key functions such as objective metric measurement, gain calculation, and level adjustment can be easily integrated as software modules into existing Digital Audio Workstations (DAWs) or broadcast systems. This could reduce development time by approximately 2.5 years compared to developing equivalent technology from scratch. The algorithm is established, enabling rapid prototyping and validation.
