I have worked on a similar use case like this before, and was able to get Flex to record the audio with the help of a few libraries. The code transcode the recorded to normal wave form before MP3 compression. If you have not found any solutions yet, I am happy to share the source code.
As for sending things to the server, while MP3 sufficiently reduces the size, if you encounter transfer issue because of size, a more reliable way would be sending data in smaller chunks, and having the server "glue" the chunks together once all the parts are received.
