Wave Enhancer

Wave Enhancer is an application designed to improve the sound quality of wave files through a series of simple settings.
The program plays Windows wave files and allows you to modify their quality by increasing their sample rate. You can also add effects such as playing the sound at slightly different times in the left and right speaker.
The wave files can be modified by clicking the “Output format” button in the top bar. The software lets you choose between two different frequencies (22,050 and 44,100 Hz), two settings for bit depth (8 and 16 bit), as well as three sound options (Mono, Stereo and Stereo effects).
However, these particular options work with low quality files exclusively and every time you try to edit higher-quality wave files, the software prompts you via a pop up window.
Wave Enhancer has a clean, user friendly interface that should be easy to figure out even by those with less experience. The app also lets you create playlists by simply clicking the button on the UI. The files in the lists run continuously and it’s possible to skip from one to another by clicking on the specific.
The app supports two different languages, English and French, which you can switch between from the “Options” tab. File association is also available, but exclusively for WAV format. The same menu allows you to play the file while it's being saved to disk or to put it on auto repeat.
Overall, Wave Enhancer is a tool with a basic design and functionality that doesn't give you much room to modify the wave files in your directories. However, compared to other similar tools, it has a very low impact on the computer's performance, as CPU usage is minimal.
