1.  Open the desired file. 

2.  Select the 'DC Offset Correction' command in the 'Enhancement' menu. The 

correction is made to the selected part of the audio file. 

 

With this command, you do not have any selection choices and it is not possible 
to check the result of optimization in advance. 

Noise reduction improves recordings where noise disturbs the sound of the 
audio file by removing undesired noises (background noise, buzzing, etc.) in a 
particular bandwidth. 

1.  Open the desired file. 

2.  In the 'Enhancement' menu, select the 'Noise Reduction' command. 

 

3. Select a presetting by clicking on the dropdown button and highlighting the 

desired list box field or set the subtraction profile, by placing the mouse 
cursor on that part of the green line that you wish to alter, – a white square 
will appear at the place where you click the mouse – and drag the square to 
the position desired. 

 

Click on the 

 button to play back the audio file with the changes stated. This 

allows you to check straightaway that you are happy with the results. 

4.  Click on the 'OK' button to take over the changes. 

Noise analysis helps in analyzing undesired noises such as background noises, 
buzzing, etc. The results obtained by analyzing the frequency characteristics of 
the noise can be used to filter this noise out of the recording.  

 

'Noise analysis' does not itself alter the audio file. However it enables 'Noise 
Reduction' to be made.
