The intensity and frequency components are represented through colors, helping differentiate speakers or sound types instantly. Designed for simplicity, the extension launches and starts capturing sounds immediately without complex setup, supporting screens 800×480 or larger and modern OS versions. It is free from advertisements and allows for easy copying to SD memory card, providing a seamless and reliable audio visualization experience.
