Free directshow audio software for windows

River Past QuickTime DirectShow Filter for WMP let you play QuickTime, MPEG-4(MP4, M4V), DV and 3G (3gp and 3g2) video, MPEG-4(M4A) and AMR audio, animated GIF and FLC animations in Windows Media Player.
It is implemented as a DirectShow filter, using the native QuickTime codecs. By using QT codecs, it has the compatbility as the regular QT Player. It is compatible with all file types supported by QuickTime - including MOV, MP4, M4V, 3GP, 3G2, DV, AMR, M4A, animated GIF, and FLC animation.
However, it only uses the codecs from QuickTime, without the additional weight of the full QT. By using the standard, multi-threaded DirectShow architecture, it is fast and feels at home in Windows Media Player. Indeed, it is often much faster than the standard QT Player.
You have to have QuickTime installed. The filter uses the codecs from the QT installation.
Once installed, you can open mov, mp4, m4v, m4a, dv, 3gp, 3g2, amr, and flc files in Windows Media Player. It is not a seperate application software.
Note, it does not change the default file association. It enables WMP to play the QuickTime files types. However, it does not make WMP the default player for those file types. You can change them yourself.
No Adware or spyware. Compatible with Windows XP and Vista, including 64-bit Windows.
