How to denoise audio files?

Drag our audio draft into the material window. (ctrl+I, choose our materials)

Double-click our audio draft, and a waveform file will appear in our operation window.

Place the mouse on the far right side of the timeline and drag the timeline selection box to the left to enlarge the timeline.

Observing the audio file, we can see that the noise in the recorded part 1.2.3 is obvious.

(If you open the software without spectrum frequency window, you can press shift+D to bring it up. )

1.2.3 output is the noise sampling we need, and the criteria for selecting noise sampling are: 1 noise time is long enough, 2 there is no recording.

Selective noise sampling

1. Zoom in on the timeline until we can easily select the noise.

2. Click the end of the noise and drag the mouse to the top of the noise.

So we chose noise sampling.

Capture noise samples

Effect-noise reduction \ recovery-capture noise samples.

Shortcut key (shift+P)

Select all audio files,

1. Displays all time axes of audio, so that you can view all waveform files.

2.ctrl+a selects all audio.

Noise reduction treatment

Effect-Noise Reduction \ Recovery-Noise Reduction (Processing)

Shortcut key (ctrl+shift+P)

1. In the pop-up effect-noise reduction interface, adjust the noise reduction parameters (80-95) and noise reduction range (30-50). The specific effect depends on the situation. If the noise reduction is too large, the sound quality will be distorted.

2. Apply and wait for the effect to be processed.

Audition shows that the noise reduction effect is obviously improved. Look at the picture, the original noise part is gone, and the noise reduction is successful.

Export audio file, ctrl+shift+s,

Set specific options for your own export. accomplish
