ShuangzSoft Audio Editor is a simple audio editor that enables you to perform some basic editing functions with audio files in either MP3 or WAV format. Therefore it's a good choice for quick, easy audio editing tasks.
When opening a file, the program shows it as an audio wave which makes it easier to work on it. It also allows you to select certain areas of the file by using markers.
The tools included in ShuangzSoft Audio Editor are changing the volume (increasing or decreasing its level), creating fade in and fade out areas at the beginning and the end of the track and also splitting audio files. You can save the results in both WAV and MP3.
