How to convert WMA to WAV files

Windows Media Audio or as it is more commonly referred to WMA is an audio data compression technology created and instituted by Microsoft. The name is also used to refer to its audio file format or its audio codecs. It is a proprietary technology that constitutes part of the Windows Media framework. WMA is composed of four specific codecs. The original WMA codec, which is known simply as WMA, was produced as a competitor to the more popular MP3 and RealAudio codecs. WMA Pro, which is a newer and more advanced codec, also supports multichannel and high resolution audio. A lossless codec, WMA Lossless, compresses audio data without the loss of audio quality. In addition to WMA Voice, which targets voice content, applies compression by using a range of low bit rates
WAV or as it is sometimes called WAVE which is short for Waveform audio format, also known as Audio for Windows, is a Microsoft and IBM audio file format standard used for storing an audio bitstream on all PCs. It utilizes the RIFF bitstream format method that allows data to be stored in “chunks”, and is therefore also similar to the 8SVX and the AIFF format used on Amiga and Macintosh computers, respectively. It is the primary format used on Windows systems for raw and normally uncompressed audio.
The WAV format is playable in most CD players and other types of music players hence it is often essential that WMV files are converted to this format for greater application outside of a PC. To convert from WMV to WAV you will need a conversion program that is capable of performing this process. It is also useful to note that some CD burning software is able to convert to this format automatically. It is often recommended that you convert WMV to WAV first even if you may intend to use the MP3 format later, this is because the WAV format will be of a higher audio quality because of its less compressed format.

Things you will need

  • A WMV file
  • A converter in this case the WinFF will be used to demonstrate the necessary steps.


To convert files from WMA to WAV, the easy solution comes in the form of WinFF. This application uses file conversion support from FFmpeg to convert between many different forms of audio and video formats.

  1. First you will need to download and install WinFF following the instructions that come with the software.
  2. Then you will need to open the application and select the WMA file or files you wish to convert to WAV.
  3. Select the Wav for CD option at the [Choose Format to Convert to] menu.
  4. Select a Destination folder to save your file(s) and then click the [Start Converting] button.


  • It is a pretty straightforward process however you should be careful when selecting your destination folder. Do not save it to a location that you are unfamiliar with as it may make locating the file a bit difficult. It is always best to save the file in a folder that is used for music storage purposes.

How to Convert VCD to MP3

MPEG-1 Audio Layer 3 or as it is more popularly considered, MP3, is a patented digital audio encoding format which implements a form of lossy data compression. The lossy compression that is used in the MP3 algorithm is designed to profoundly decrease the amount of data needed to represent the audio recording while still sounding like a pretty good reproduction of the original uncompressed audio for the majority of listeners who use this format. An MP3 file that is developed using the setting of 128 kbit/s will produce a file that is about 1/11th the size of the CD file created from the original audio source. An MP3 file can also be generated at higher or lower bit rates, with higher or lower resulting quality.
Video CD which is almost always abbreviated as VCD, is a standard digital format used for storing video on a Compact Disc. VCDs are able to be played in conventional VCD players, most modern DVD-Video players, personal computers, and within some video game consoles. The VCD standard was established in 1993 by Sony, Philips, Matsushita, and JVC and is considered the White Book standard. Video CDs are authored using the Mode 2/XA format, allowing an estimated 800 megabytes of VCD data to be stored on one 80 minute CD in comparison to 700 megabytes when using Mode 1. This in combination with the net bit rate of VCD video and audio, means that an estimated 80 minutes of VCD content can be stored on a conventional 80 minute CD, 74 minutes of VCD content on a regular 74 minute CD, in essence it may use the exact amount of time specified by the CD. The VCD standard also provides the user with the option of creating DVD-quality still images/slide shows with audio, at resolutions of 704×480 (NTSC) or 704×576 (PAL/SECAM). Version 2.0 has the playback control (PBC), which features a simple menu akin to DVD-video.
Sometimes it may be necessary to convert a VCD to MP3 for increased compatibility with a wider range of products and also as a better storage solution. To accomplish this you can use any software that is able to convert from VCD to MP3.

Things you will need

  • Conversion software for this demonstration is an Audio/Video to MP3 Maker.

It is a format that is used particularly for multimedia; it is mainly used to house digital audio and video information. It may consist of other data forms including subtitles and still images. MP4 is being used more widely these days. Its popularity is largest among the latest iPod players and PSP users. This form of file compression provides a suitable method of storing DVD quality movies at an appropriately small size to optimize storage. The form of compression used to achieve this is called MPEG-4 compression.
DivX is a brand name of products established by DivX, Inc. or as it was formerly known DivXNetworks, Inc. It includes the DivX Codec which has become extremely popular as a result of its ability to compress lengthy video segments into small convenient sizes while maintaining relatively high visual quality. The DivX codec uses lossy MPEG-4 Part 2 compression, where the quality of the video is balanced against the file size for utility. It is one of a number of codecs generally associated with “ripping”, which is basically the process of transferring audio and video multimedia to a hard disk where it is trans-coded.
One may choose to convert MP4 to DivX to minimize the space used for video storage. It is essential to note that the DivX format is more often than not housed as an AVI file. To convert from MP4 to DivX you will need the corresponding software, in general it is a quick and relatively direct process to initiate.

Things you will need

  • Software to convert the video in this case is Open Video Converter
  • The appropriate video decoder for your MP4 file
  • The appropriate AVI video decoder for your DivX file
  • The MP4 video you wish to convert.


  1. First you will need to install the appropriate video decoder and audio decoder for the mp4 format such as FFDSHOW.
  2. Then install the avi video or audio encoder for your DivX file.
  3. If you have not installed your video converter you will need to do so at this point. For this set of instructions it is assumed you may have used Open Video Converter.
  4. Launch Open Video Converter
  5. Click on the Open Video button, and select an mp4 file for conversion from mp4 to avi.
