My client needs to let a user record a message from the browser, then export the message as an audio file (e.g., WAV).
How is this best accomplished? Flash, Java, HTML5? By best, I mean something that is straightforward to implement and also broadly supported.
What are people's experiences using HTML5?
Thanks!
Well I suspect that such a feature of HTML5 would be pretty non-standard, and the browser support would differ a lot (with many browsers not including any).
Java is not as popular as flash and there are many people who don't have JRE's at all.
So all in all I would go for the Flash solution in this case. And maybe with an HTML5 fallback for some limited cases, shall resources allow.
Flash is one option but you need a media streaming server (Adobe Media Server, Wowza, Red5). There is no way to capture and store audio on Flash locally to a file.
If you are willing to go with Java applets there are multiple solutions. All of them require access to local filesystem and will ask users for additional permissions. For example try http://www.javasonics.com/ or Google "applet record audio".
