What is the main characteristic of Wide Dynamic Range Compression (WDRC)?

Wide Dynamic Range Compression (WDRC) is primarily characterized by its ability to divide the audio spectrum into multiple bands. This division allows for more precise control over how sounds of varying intensities are processed, ensuring that soft sounds are amplified while keeping louder sounds from becoming overwhelming. This feature is essential for individuals with hearing loss, as it enables them to have a more balanced auditory experience across different frequencies and volumes.

WDRC's functionality across multiple frequency bands helps in minimizing distortion and maximizing clarity, especially in complex listening environments. This is particularly useful because human hearing is sensitive to different frequencies in various ways, and by addressing them in separate bands, WDRC can enhance overall sound quality significantly.
