	~~Also known~~ as WMA Standard or WMA Std, it was created by Microsoft to compete against [[MP3]], ~~that was quickly becoming a de-facto standard~~ format for lossy compression. ~~Once~~ the ~~second-most widespread lossy format~~, ~~there is as~~ of ~~2021 only one major music store that even offers WMA lossy downloads~~<ref>https://en.wikipedia.org/wiki/~~Comparison_of_digital_music_stores~~</ref>. ~~There are still around hardware~~ WMA ~~players~~ - ~~including in~~-~~car units~~.		The original WMA codec, later referred to as WMA Standard or WMA Std, was created by Microsoft to compete against [[MP3]], the market leading format for lossy compression. It was released in 1999, and an upgrade later the same year; those are sometimes referred to as WMA 1 and WMA 2.

	Windows Media Audio Professional (WMA Pro) was ~~recently released in the~~ early 2000s to address limitations in WMA Standard. It supports [[multichannel]] encoding and high resolutions (24bit, high [[sampling rate]]s). Improving over WMA standard, WMA Pro scored as statistically tied with top encoders in independent listening tests at the time (without lending credibility to Microsoft's claim of MP3 quality at half bitrate), ~~but like~~ WMA Standard ~~it is largely abandoned~~.		Windows Media Audio Professional (WMA Pro) was an early 2000s further development to address limitations in WMA Standard. It supports [[multichannel]] encoding and high resolutions (24bit, high [[sampling rate]]s). Improving over WMA standard, WMA Pro scored as statistically tied with top encoders in independent listening tests at the time (without lending credibility to Microsoft's claim of MP3 quality at half bitrate). Supporting multichannel, it was at some time seen as a potential competition to [[DTS]].

			Like WMA Standard, WMA Pro also came in revised versions: WMA Pro 10 offers an additional layer atop the original WMA Pro 9, information that will be lost on a "WMA 9" player.

This codec, introduced with Windows Media 9, was used in the Microsoft telephones. It was considered to deliver very acceptable voice quality at bitrates around 4 and 20 kbps. It would allow switching over to the WMA Standard algorithm for signals with both voice and music, and Microsoft's encoder could detect music and switch over automatically.
