DC offset correction improves recordings from poorly calibrated equipment (not 
centered around the zero point). The subsonic frequencies are removed and 
with them the DC errors. 

1.  Open the file of your choice and select the appropriate area. 

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. 

The filter toolbox filters interference frequencies out of the recording. It has not 
only the normal functions such as low, high and bandpass filters, but also a 
user-defined frequency curve and three individual notch filters. The notch filters 
can be used to remove specific interference such as the buzzing of the power 
supply.  

1.  Choose 'Filter Toolbox' from the 'Enhancement' menu. 

 

2.  Check the box in the 'Band Pass Filter' area if you want to use this filter, and 

specify the upper and lower limits of the frequency range by turning the 
corresponding knobs.  

3. In the 'Notch Filters' area, choose the filter you want and specify the center 

frequency by turning the knob.  

4.  Check the box in the 'User drawn filter response' area if you want to use your 

own frequency. You can draw this using the green line. 

 

Clicking on the 

button plays the audio file with the specified changes. This
