Increase Sound Quality of MP3 and WAV Files with Vloud
Vloud is a free online audio tool which allows you to increase the volume of your MP3 or WAV files to light, loud, louder and download the file again to your computer.
All you need to do is to browse for the MP3 or WAV file that you want to increase the sound quality and upload it to Vloud; it will take some time depending on your file size. After the finishing of uploading process, you can download the same file with high quality sound without increasing the size of the MP3 file. The maximum file size supported by Vloud is 10 MB.
There are also other ways to increase the quality of MP3 files such as increase the bitrates of MP3 files using Nero audio encoder, but it also increases the size of your MP3 file as you increase the bitrates. You can compress it again but this will turn out to provide lossy format.
