How to remove
the clicks and pops
from an Audio File
- To remove the clicks and pops from an audio file, you need to use the DirectX plugins.
- Select the file that you want to clean up.
- Go to the DirectX plugins dialogue box. The DirectX plugins are located in the Toolbox menu under DirectX.
- Select the DART De-Click plugin and click OK.
- Smoothing: This is a filter used to smooth/reconstruct the signal in the first stage of noise canceling procedure. Selecting greater values of the smoothing factor may result in a sound that is relatively clean, but muffled and dull. Un-checking the smoothing box will turn off smoothing. We recommend that you keep the smoothing at its default values until you are more familiar with how it works.
- Postfiltering: Postfiltering is effective in reducing tape hiss and surface noise. It can provide considerable rates of noise suppression on silent parts in the recording, and still retain sharpness and freshness of the original sound in its louder parts where the noise is less audible. Un-checking the Postfiltering box will turn off Postfiltering. We recommend that you keep Postfiltering at its default values until you are familiar with how it works.
- Outlier Detector: The outlier detector is a device used to localize impulsive disturbances throughout your sound file. Setting the detector at low values could cause the file to sound like there more clicks than before or make the music sound like it is clipping, because to low of a detection threshold would set off too many false alarms. On the other hand, when relatively large values of detection threshold are adopted, the detector may become to "tolerant" and fail to isolate small noise pulses. Un-checking the detection threshold will turn of the device. However, if smoothing and Postfiltering are unchecked as well then the resulting file will be identical to the original one.
- Maximum Length of Detection Alarms: The maximum length of detection alarms, which can be chosen in the range <1,100>, determines the maximum number of samples in a row that can be scheduled for reconstruction in the automatic detection mode. We recommend you use the default value of 50.
- You may want to change the name of your new file, and you can do this by clicking on the "Change" button. When the dialogue box pops up, enter the name you want to use, and click save.
- You are now ready to De-Click. Click on the process button.
- After the processing is complete, your file will be created with the resulting changes.
- You can now play the new file to make sure it is to your liking.
