Using the Hiss Reduction effect (Edit View only)
The Hiss Reduction effect reduces hiss from sources such as audio cassettes, vinyl records,
or microphones. This effect greatly lowers the amplitude of a frequency range if it falls
below an amplitude threshold called the noise floor. Audio in frequency ranges that are
louder than the threshold remain untouched. If audio has a consistent level of background
hiss, that hiss can be removed completely.
Using the Hiss Reduction graph to adjust the noise floor
To reduce other types of noise that have a wide frequency range, try the Noise Reduction
effect. (See “Using the Noise Reduction effect (Edit View only)” on page 128.)
