Sound brightness refers to the perceived quality of a sound that determines how sharp or dull the sound is. Bright sounds have higher frequencies and are more intense and clear, while dull sounds have lower frequencies and are softer and less distinct. Adjusting parameters like frequency content and amplitude can alter the brightness of a sound.
