Saving voice recordings

[Scott Matheson <sm...@intralinks.com>]

Hi
    We have a working app that records a student voice, saves the binary on a server letting the teacher download

However the files are big, and the upload does not always work, the upload seems to not complete, is this a problems with flex?

First does any one have the above concept working, recording voice, saving to server then downloading

Also is anyone recording / converting to as smaller format ie mp3

Last has anyone done the above with a media server ?

             We have been working on this for a few weeks, local play back of the student voice is fine, the last part is were we have had the issues ie the transformation and saving, if you could share you code that would be a big help

We are fine with the play back from MP3, we have 15,000 prerecorded mp3 as part of our apps and that works fine

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.
