Apple Releases iTunes SDK for Windows
amichalo writes "Apple's recent release of an iTunes SDK for Windows provides the ability for third party programs, such as WinAmp and Windows Media Player, to support the AAC file format. Ars Technica has additional commentary. The SDK uses the COM interface and supports iTunes 4.5 only."
Well, iTunes for Windows actually uses Quicktime for playback.
Theres this nice project over at SourceForge http://sourceforge.net/projects/qtcomponents/ with Ogg Vorbis components for Quicktime (and thus iTunes). It's still beta, and there is a pause when iTunes switch between formats, but it plays Ogg Vorbis.
The crossfading can be found under Edit->Prefrerences->Effects.
Winamp 5.x already supports AAC out of the "box"; it will rip to AAC quite transparently.
Check it out... www.winamp.com; its worth it for the shoutcast capabilities alone.
