Audio file in Microsoft Windows Media format

WMA file format icon

WMA is a file extension used with Windows Media Player. WMA stands for Windows Media Audio. WMA is both an audio format and an audio codec. WMA was intended to be a competitor for the MP3 and RealAudio audio formats.

There are 4 versions of the WMA codec:

  • WMA is the original codec, and was initially released in 1999.
  • WMA Pro is an improved lossy codec intended for audio professionals, though it is limited by the current range of hardware and software needed to support the codec.
  • WMA Lossless is a lossless codec intended for archival and storage purposes. Using VBR, it can compress the audio file without any loss of quality.
  • WMA Voice is a lossy codec that was designed for low bandwith voice playback applications.

MIME type :audio/x-ms-wma

I checked on WMA because I need to convert my CD library to USB & Phone media. Having ripped a music CD using WMP, then burnt it onto a USB stick, while the album was present I could not play it on my PC or in the car as files not recognised! I was lookingh for a way to convert WMA files to MP3 for playback anywhere. I would have thought it would have been MUCH SIMPLER to burn an audio CD straight to MP3 format, but of course as usual, MS Windows always tries to make it far too difficult to achieve the logical outcome!

I wanted to put a variety of music onto a USB to make it easier for use in the car. I could not understand why some albums did not appear until my grandson suggested it may be in the wrong format...can I change the format??
