Cross platform Voice Recorder and player

We need an simple web based voice recorder that will work with mobile devices and standard browsers. User presses RECORD App captures the audio from his/her device and records for a pre-set amount of time. User can play back the audio and either click SEND or RECORD AGAIN Video file is immediately saved and posted as a playable link below the recorder. Admin access to delete select audio files from web interface Something similar to [login to view URL] would be fine I would prefer this to work on mobile devices as well as desktop computers, but if this proves difficult or expensive, I would be happy to stick with desktop browser only. No flash Locally hosted application, no servers Joomla integration would be nice
