Clean Up Background Noises In Avs Audio Editor

AVS Audio Editor, produced by Online Media Technologies, is an inexpensive, simple to use application that allows you to record and edit audio from virtually any input device or source file. Although not as comprehensive and feature rich as higher-priced applications, AVS Audio Editor contains all of the controls and effects that most home or amateur users require. One handy feature included with the program is the Noise Removal tool that lets you quickly eliminate hiss, pops, clicks and other background noise from audio files. Mastering use of the Noise Removal tool takes a little practice, but is not that difficult.


1. Launch AVS Audio Editor by clicking its desktop icon. Alternatively, click “Start,” “All Programs,” “AVS4You,” “Audio” and then “AVS Audio Editor.”

2. Click the “Open” button on the AVS Audio Editor toolbar. Navigate to an audio file on your computer that you want to edit and from which you want to remove background noise. Highlight the file and click “Open.” AVS Audio Editor displays a waveform graph of the audio file in the display window.

3. Click “Noise Removal” on the toolbar. In the Noise Removal window, click the “Get Noise Profile” button. Use your mouse to select a silent portion of the audio file or one with very low volume levels. Click the waveform graph at the point where a silent or low-volume level portion of the track begins, then pull the mouse to the right to select a part of the file. Release the left mouse button. If the frequency spikes are too close together and you cannot select a range or portion of the waveform graph, click the magnifying glass with the “+” symbol to zoom in on the waveform graph.

4. Click the “OK” button in the “Get Noise Profile” window. The Noise Removal window again appears on the screen. Click the “Default” link in the Presets list to use standard noise-reduction filters for the file. Alternatively, use the “Smoothing,” “Noise Reduction” and “Noise Bandwidth” sliders to create a custom background noise filter setting.

5. Click the “Preview” button, to listen to the audio file with the selected noise reduction filters applied. Click the “Stop” button to cancel the playback of the preview selection.

6. Click the “OK” button if the sound of the audio file is acceptable to you. Alternatively, adjust the sliders to increase or decrease the level of noise reduction for the file. Click the “OK” button to apply the filters and changes to the file. Wait a few seconds for AVS Audio Editor to apply the background noise filters to the entire file.

7. Click the “Save” button on the AVS Audio Editor toolbar. Click “Yes” to overwrite the old filename or “Save As” to save the edited file with a new filename. Close AVS Audio Editor.
