What is a WAV file?

WAV is also known as Waveform Audio File Format and this file format is used to store audio data along with bit rate, sample rate, and other data. This format was first created and used by IBM and Microsoft in August 1991, and since it has been used in different places. This format is very popular on different platforms such as Windows Media Player, iTunes, VLC, and many more. A WAV file is used to store uncompressed audio data which can be store 2GB in older devices and 4GB in modern devices. 4GB of audio file is equivalent to 4.5 hours of audio however, the bit rate will affect the size.

WAV files are much bigger in size and not as popular as MP3 as the data is uncompressed. Uncompressed data takes more space on the disk compared to compressed audio formats. For example, 4GB WAV files can contain 4.5 hours of audio, and 4GB of MP3 file can contain 1000 songs or 4000 minutes = 60 hours of audio. However, the quality does suffer because of compression and takes more time while reading compared to an uncompressed format.

Uncompressed data is like chunks when compared to compressed data and have “raw” audio data, raw data is very useful for music producers. Raw data contains more information on the audio and gives you more audio editing options.

What is a WLMP file?

In the latest version of Moviemaker, it uses WMP format instead of WLMP format. The WLMP file stands for Windows Live Media Player and is used for Movie Maker Project by Microsoft. Older versions of the Movie Maker used to store the file with MSWMM file extension. These extensions were used whenever you worked on Windows Movie Maker and saved any of your projects. But WLMP format file can not be opened with any other player, not even third-party applications. So converting these files into MP4 is a necessary step, especially when you have no interest in opening Movie Maker. 

If you are using the older version of Movie Maker then the extension will be MSWMM, after several updates it started using the WLMP format. In the latest update aka Movie Maker 10, it uses WMP format. Keep in mind that the formats change but the core functionality of the app and file remains the same. Change of extensions maybe is done for better compression of the data or ease in transferring over the net. This method is pretty common on different applications but in most cases, the update supports the previous extension

Note: WLMP files do not contain the actual media rather it contains the location of the media file along with all the effects, transitions, and more. The WLMP file doesn’t even contain photos or music but only their location on your local disk.
