Audio Volume Smoothing Using Moving-Average Target Control

The patent implements a single time-to-volume table that can generate multiple gradual volume change patterns (fade-in, fade-out, volume swell, volume shrink) by varying control parameters such as start time, end time, and application timing. This universal approach allows the system to achieve diverse volume control patterns without storing multiple separate tables, thereby reducing data storage requirements while maintaining full functionality.

The patent pre-calculates and stores volume values in a time-to-volume table at predetermined time intervals, eliminating the need for complex real-time calculations during execution. The system simply retrieves and applies pre-computed volume values based on the current time and pattern parameters, achieving precise volume control through straightforward table lookup and interpolation operations rather than complex algorithms.

The patent dynamically adjusts the volume according to the selected gradual change pattern (fade-in, fade-out, swell, shrink) and the current time relative to the pattern duration. Instead of applying target volume changes directly, the system calculates intermediate volume values based on the progression through the pattern, ensuring smooth transitions that respond to user actions while avoiding sudden jumps that would cause discomfort.
