Hi,
Sorry for my late reply.It is the files with AAC extension.But if you go to wikipedia there are two versions of AAC one is AAC and other one is AACplus.The latter one is the advanced version.
You can check the shoutcast.com website where you will find Radio stations with AAC+ file extensions.So I was talking about application development which can stream AAC+ files.At present QT Tool kit supports MP3 and AAC not the latest one so planning to support the same for my own test application.If you can help me on this let me know.
Thanks in advance
