ADOBE AUDITION 175 User Guide 5 Select the entire file (or the portion you want to noise-reduce). 6 Go to Effects > Noise Reduction >Noise Reduction again. 7 Click on OK to perform the noise reduction. Special The options in this menu can be used to introduce some processing effects that are both innovative and wild-n-wacky. Have fun and experiment. Convolution Convolution is the effect of multiplying every sample in one wave or impulse by the samples that are contained within another waveform. In a sense, this feature uses one waveform to "model" the sound of another waveform. The result can be that of filtering, echoing, phase shifting, or any combination of these effects. That is, any filtered version of a waveform can be echoed at any delay, any number of times. Convolution dialog For example, "convolving" someone saying "Hey" with a drum track (short full spectrum sounds such as snares work best) will result in the drums saying "Hey" each time they are hit. You can build impulses from scratch by specifying how to filter the audio and the delay at which it should be echoed, or by copying audio directly from a waveform.
