Real-time audio record/playback from a Ruby web app

I am wondering if anyone has success with audio record (from microphone on the users browser) and playback from a web based app (Ruby/RoR)?

What I have found so far - I could write a flex/flash app which will record the audio and then have a server side like Red5 or so to receive and convert. This sounds more involved and I also saw different types of hosting issues etc people are having - so I am thinking there may be better/easier solutions out there!! I looked at html5/web-kit too but seems to only works on chrome and is limited to text fields etc.

In my app, i want to record users voice, save it on a aws/s3 as mp3 or similar file format and play it back to user within the app based on users input/choice. While flash based solution is workable for now, non-flash based solution will be preferred as it will support more devices (you know devices I am referring)..

There is a way using HTML5 and a server. Just record a video.
Convert the video to audio, then use the audio as you wish.

This implementation takes audio from a video and runs ffmpeg to extract the audio:

This is in PHP, but it should not be too hard to create a Ruby version. Easy peasy.

The only options for web based record are Flash, Silverlight or Java. None of these will work on an iPhone or iPad - You will need a native app for that.

You don't need to use Red5 for Flash recording - you can record direct to memory, optionally encode (or zip), and then upload the the data. You might be better doing mp3 encoding server-side using ffmpeg or SoX before moving the file to s3.
