How to Convert Mp3 to Wav

The WAV format is a lossless audio format, which means that audio copied in this format is an exact duplicate of the original and maintains the same quality as the original file; WAVE or WAV stands for Waveform Audio File Format and was a joint-project by Microsoft and IBM. The WAV format was the primary format used on the Windows operating system for storing audio files that were copied from audio CDs; however in more recent times the WAV format has been superseded by the WMA format on Windows operating systems.

The MP3 format is a lossy audio format which means that unlike the WAV format, the original file does lose some of its quality when converted; however currently the MP3 format is the most popular audio format worldwide because the human ear is not able to identify the loss in quality. The MP3 format was designed by the Moving Picture Experts Group (MPEG) and was intended to work alongside the MPEG video standards.

Even though MP3 is the preferred audio file format for everyday use, the WAV file format is stilled used for some applications; audio or video editing applications may work better with the WAV file format as opposed to other audio formats and WAV can be considered as the PC equivalent to the audio CD format. Whatever the reasons may be converting an MP3 to WAV is no more difficult than the reverse, and once completed you may use the WAV file for whatever reasons you may have.

Things You Will Need

PC or laptop

MP3 files

Adequate hard drive space

Conversion software

Internet connection (optional)


Locate the MP3 files you would like to convert to WAV.

Preferably copy all the MP3 files to a single folder for ease of management.

If you have no conversion software you may either download a free application such as Format Factory or purchase one such as NCH Switch.

Once downloaded install the application and run it.

Locate the option to convert to WAV from the application interface if applicable.

Drag all of the desired MP3 files into the application or the folder if the program supports it.

Hit the button to start the conversion and wait for the process to complete.

Once completed either locate the destination folder or open the output folder from within the application and your converted WAV files should be there.

Do’s and Dont’s

Do not purchase conversion software unless you find it absolutely necessary to do so, or if you have tested and found that a paid application works faster than an available free one.

Don’t set the bitrates for MP3 files too high or too low when converting them as setting it too high increases the size of the file without noticeable improvement in the quality; conversely, setting the bitrates too low will adversely affect the quality.

Bear in mind that if the quality of the MP3 file you are converting was poor to begin with, converting it to the WAV format will not improve the quality.
