  • EZ Clean Filter Example

    In this tutorial, we’re going to use the Classic Source/Destination mode to run you thru the software. You can choose this mode by clicking on Edit/Preferences in the program. Make sure the check box that is labeled Enable Fast Edit is unchecked. If you just unchecked it, close and restart the program to get going in Classic mode.

    Next, open the Demo1 .wav file the way we did in the testing section above.

    Listen to this file by either clicking the Play button or hitting the spacebar – it’s full of clicks, hiss, low frequency noise, etc. It’s a mess. Stop the playback when you’re done listening.

    And, now let’s get to the fun part. Click the Filter Menu and choose EZ-Clean. The filter looks like this:

    EZ Clean Is Almost Too Easy
    Notice that there are only three sliders, one for scratches or clicks, one for crackle (or small clicks) and another for hiss or other continuous type noises. We are simply going to listen to the audio and move these three sliders as we listen.

    Move each slider to approximately the settings shown above. We don’t need to be perfectly accurate, just set them similar to what you see. When you move these sliders to the left, the filtering becomes more aggressive. Now click the Preview button. You’ll start to hear the audio. To stop a Preview, just click the preview button again and it will stop in a toggle switch sort of action.

    Now, in Preview mode, listen for a second or two. Now click the checkbox labeled Bypass. This “bypasses” the filter and stops the filtering. You are now hearing the original music without the filters in place. Note the large amount of clicks and hiss.

    Uncheck the bypass box to start filtering again. What a relief! That’s much better isn’t it? But, you can do better yet. Move the Hiss slider a bit farther to the left until you remove more of the random noise. Remember, moving the sliders to the left, makes them filter more, so just slide them until you are happy with the result. If you move the controls too far to the left, you may introduce digital artifacts and/or distortion into the signal. You must strike a balance between noise reduction and artifact/distortion creation with these tools.

    Now note the Hum filter on the EZ-Clean screen. If you live in the US, you’ll check the 60 Hz box to remove power line hum. If you live in Europe, you’ll check the 50 Hz box. There are many other tools to remove larger amounts of hum in DCArt10, but this one is quick and easy.

    Now, stop the preview by clicking on the Cancel Button in the Progress- box. Click on “Run Filter” and you now have a destination file that is fully cleaned! Could this possibly be any easier?
