We need several file formats of the audio file because different browsers support different
formats. With the help of the SoundJS library, we provide three to four formats, and the
library will choose the one that can be played in the browser.
The following table shows the audio format support available at the ime of wriing this topic:

Actually, browser compaibility is more complicated than what is shown in the preceding
table. The support is different for different browser versions. The mobile version of browsers
makes things more complicated. I recommend checking the browser support online while
working on a new project. It is because the browser upgrade may add or remove support for
certain audio formats. The following URL contains a good aricle on the latest web audio:

Note that the MP3 format is not really free to use. The patent of MP3
makes serving MP3 files to individuals cost a huge license fee. So, please
use MP3 cauiously and only as the last choice. The following URL is one
among the many aricles that discuss the issues you get using MP3 and
web audio:
