"VoiceNotes for Android": Sample App using Flex, AIR, and the Microphone API

VoiceNotes for Android is a sample application built with Flex and deployed on Adobe AIR for Android. The application allows you to record voice messages and play them back later. It demonstrates the Microphone API introduced in the latest builds of AIR for Android. VoiceNotes for Android is based on the desktop version of VoiceNotes I recently blogged as an AIR 2 sample.

If you want to compile or run the application on your device, make sure you install the latest version of the AIR for Android SDK and Runtime respectively. The apk was built using the AIR for Android 20100720 build.

    Great post! Christophe, do you know how can I compare to sounds files to see if booth have the same audio? If yes, can you make a new post teaching how to do it or a link with a sample to my email?

    Newbie alert!!

    when i download the fxp file and load it into flash builder “burrito” it gives me a “desktop application” not “mobile Application” . How do I change this so I can build it for the mobile environment and then download and run on an android device?

    Hi Christophe,

    Thanks you for the wonderful information. I have downloaded the application for android, and checked it is working absolutely fine when recording is happening. The problem I am facing is when I am doing full duplex that is when some thing is both the capturing and playback (through speaker) are happening simultaneously, then the captured audio is getting clipped and distorted may be due to the high sensitivity of the mic or loud volume of speaker. When I am reducing the speaker level I am not able to hear audio only. So I want to reduce the mic level. How to do it. Any information on this will be greatly helpful.

    Thanking you,
    ksam.

    Hey there just wanted to give you a quick heads up. The words in your content seem to be running off the screen in Firefox.
    I’m not sure if this is a formatting issue or something to do with web browser compatibility but I
    figured I’d post to let you know. The design and style look great
    though! Hope you get the issue fixed soon. Kudos

    […] I'll share what I know, which is not terribly much, I'm afraid, but may get you started. There are two providers for android – Vlingo and Google voice. When you use speech-to-text voice samples are sent to one of these providers servers, yes they are, you can read the fine print – don't believe me, use wireshark or similar to trace it out. Most of the information in proprietary on these system's so it is hard to say. Check this out for some overview Speech recognition – Wikipedia, the free encyclopedia As far as sending samples to your own database, I think it is doable, you'll have to work with MediaRecorder and/or Sensors (MIC).
