I have a wmv file which contains only video and i have a wav file of
the same duration as the wmv file. I would like to know how i can add
the audio data to the wmv file.

There's a StreamEdit interface exposed by the WM Encoder SDK

I would like to know whether it is necessary to convert the wav file
to wma? I was reading the same thing on another fourm where one of the
users had the same question as mine. In a reply someone told that the
wav has to be converted to wma before doing the stream edit operation.

Yes - the stream editor interface only operates on ASF content (i.e.
WMA or WMV), I'm not sure if it requires the content to be indexed
(probably not - which stream's index would it pick ?).

WAV just wouldn't work as an input format there, and as you can see
it's not listed as a source type in the stream editor application
(only ASF, WMA and WMV are listed)

Specifically in the SDK, WMEncStreamEdit interface doesn't offer any
encoding options - if you follow the examples in the SDK, you can
setup your sources, then call Stream.Validate and catch an exception
if the stream type is unsupported (it should be, for WAV).
