How do I send the metadata header to the icecast server ? I am recording in AAC and streaming it to the icecast server through ios but the file shows corrupt . I suspect that the metadata needs to be added to be able to play a file. How do i send the metadata ? SHould i send it as a string ? What should be the format ?

The metadata is not required for a stream to function. If your data is corrupt, you are either encoding it wrong or are sending the wrong Content-Type header.
That being said, once you get your stream working, if you would like to send metadata, this is done out-of-band of the actual audio stream. Metadata is updated with a simple HTTP request to the Icecast server.
