File extension swa file type description:
Adobe Shockwave music file

The SWA file extension is associated with Adobe Shockwave (formerly Macromedia Shockwave), which  was Macromedia's first and most successful multimedia player prior to the introduction of Macromedia Flash (now Adobe Flash).

In an attempt to raise its brand profile all Macromedia players prefixed Shockwave to their names in the late 1990s. Although this campaign was very successful and helped establish Shockwave Flash as a dominant multimedia plugin, Shockwave and Flash became more difficult to maintain as two separate products. In 2005, Macromedia marketed three distinct browser player plugins under the brand names Macromedia Authorware, Macromedia Shockwave and Macromedia Flash.

A *.swa file contains audio data playable with Shockwave.
