Step 1 – Open File
At first, you have to open the MP3 or other audio or video file you want to fade in. To do that press on the “Open” button of the toolbar or select “Open” from the “File” menu.
You can also drag and drop the audio or video file to open it.
Step 2 – Select the part of the MP3 file you want to fade in
Secondly, mark which part of the MP3 file you want to fade in.
You can do this by selecting the part of the MP3 file’s waveform you want to fade in.
Alternatively, if you know the start and end time or duration of the desired fade, enter the start time, end time or fade duration in the appropriate textboxes.
Step 3 – Fade
Now press on the “Fade In” of the toolbar.
Alternatively, you can select “Fade In Selection” from the “Effects” menu.
Step 4 – Specify Output Format Settings
Press on the “Output Format” button to specify various output format settings or leave the default ones.
Step 5 – Get the Result
Lastly, select “Save Whole Clip” from the “Cut” menu to get the result file.
In case, you want only a part of the MP3 file, after selecting it, you can choose also “Cut Only Selection” from the “Cut” menu.
