Part 3. FAQs

1. How to open a WAV file

There are plenty of third-party software capable of opening a WAV file. However, most users won’t need to seek it out. This is because Windows and Mac systems open the WAV using pre-installed programs.

For Windows, if you double-click a WAV file, it will open using Windows Media Player. For Mac, if you double-click a WAV file, it will open using iTunes or Quicktime. If you’re on a system without these programs installed, then consider third-party software. We recommend Audacity for its extensive features and ease-of-use.

2. Which one is better, WAV or MP3?

  • Advantages of MP3 Small File Format, Compresses Files with Little Perceivable Difference to the Overall Sound Quality, Easy to Convert a WAV or CD to MP3 with Free Software
  • Disadvantages of MP3 - Degraded Quality, Compression Artifacts, Not Suitable for Professional Work
  • Advantages of WAV - Retains full Quality, Simplicity, Advancements in Home Recording
  • Disadvantages of WAV - File Size

Despite several advantages and disadvantages for each, the argument over MP3 or WAV will always come down to quality vs. size. So, the first question is what do you need the file for?

If you are an artist hoping to release a single, most online music stores require the WAV format. When your music is streamed, it’s going to be in some lossy format even if not uploaded as an MP3 file. An MP3 converted to a WAV will still be missing all of the data discarded in the MP3 encoding. So, don’t start from a point where it could only get worse. Imagine paying a mastering engineer to add the final polish then handing over an MP3 to work from. The point is an MP3 will never be better quality than a WAV under any circumstances. When quality is the most important thing always use WAV. If you want to share a demo or idea quickly use MP3.

There are far too many examples to list but it’s common sense, decide what’s more important, quality or speed and size.


Now, you know that there are various methods to convert WAV to MP4, including the best way and free online methods. It is totally up to you which tool you choose to convert the WAV files, but we strongly recommend you to use Aicoosoft Video Converter as your best WAV video converter so that you can get the best user experience.
