To replace the original audio of your video file with another sound, do the following:

• use the Open button to import the audio file you wish to overlay into AVS Audio Editor - the audio file will be placed on the Files tab below the already opened video file;

• highlight with the mouse the part of the audio file you want to copy to your video, right-click the highlighted fragment and select Copy from the express menu;

• double-click the video file for its audio track to be displayed;
• place the cursor in the position where you want the copied fragment of the audio file to begin;
• right-click within the Waveform Display area and select the Paste Mix option;

• in the opened window set the original/pasted audio volume relation and click OK. Set Amplify Paste to 100% and Amplify Selection to 0% to mute the original sound completely.
