Using flex,As can we record sound from microphone and store locally and and upload later?? Is there any relevant links to this please indicate
Check this link for how to use the microphone to record and use FileReference to save the recording
It is possible to record audio using the Microphone API SAMPLE_DATA event. The data property of the event is a ByteArray with the audio data.
A web based Flash application could copy these data samples to a data structure in memory and prompt the user to save the data to a local file. An AIR application would be able to write the data to the file system or SQL database directly.
See the links below for accessing audio from the microphone in ActionScript:

It may help to encode the data in a standardised format to help with reading and editing later (WAV or PCM). You may also want to use compression to reduce the file size for transmission (eg: Ogg Vorbis codec from Adobe).

I'm generating a 44100hz dynamic audio stream in Flash using a flash.media.Sound object and the SAMPLE_DATA event. I'd like to be able to analyze the output instead of just listening to it.
What would be the most straightforward way of converting my Flash stream of float samples to an audio file, in a standard format that can be opened by an audio editor? Is there any audio format that would be particularly suitable for this?
If you don't want to listen to it, there's no need to use Sound or the Event.SAMPLE_DATA at all. Just create the numbers and store them in a ByteArray or other data structure.

A format that can be opened by your audio editor would be preferable.
Otherwise, this totally depends on what you want to do with the sound data.

To use an existing library that encodes the data into the specified format.
tonfall supports "various audio formats Wav AIFF RAW PCM (no header) "Encoder/Decoder
WaveEncoder from Nicolas Bretin apparently encodes to WAV
Of course, if you know the specification, you can write your own encoder.
I have a problematic situation that I wish to expose you because it contains some opposites constraints. Maybe someone will have an idea on how to unlock my problem.
I'm going to make a mobile application with ActionScript 3 and Air for iOS and Android. This application has to download zip file which it uses to display text, bitmap and sound.
This last one is the problem.
After some research, one of the best way I found to check a zip file is FZip, but it allows us to get data from zip on a ByteArray form. And a Sound can't be converted from ByteArray. ( That's what a lots of results about it appear to say. )
One of the solution proposed is to put the ByteArray of a sound and put it in a SWF. Then take the SWF from the zip to get the Sound.
I can't do that because this zip will be uploaded from a admin interface used by anybody. I can't force them to use Flash.
I have few potential direction where I ask for your advices :
• Use Code or Native Extension ( iOS and Android ) to check a zip without files read in ByteArray
• Convert a ByteArray into Sound without have to pass it in a SWF
• Dynamicly create a SWF with the ByteArray of a Sound
• In the last possibility, another way to drag and download few files together which can be consulted in another format than ByteArray ( Like a iOS Bundle but with android too )
Thanks a lot to help me,
You can simply write the ByteArray on a local mp3 (or mp4) file and then play it, to write a ByteArray to file see documentation here.
It it possible to merge sound captured from microphone with an mp3 file selected and save as a new mp3 file in windows phone 8?
Does naudio have wp8 support??
Possible, yes. But you would have to decode the mp3 file into raw PCM data that matches the waveformat of the captured audio data, merge the pcm data (either an additive or mean merge or you'd simply add the captured audio data to the end of the pcm data from the mp3) and encode your new pcm data to MP3. There are plenty of libraries out there that support encoding/decoding of mp3 data and you might even find one that would let you decode/re-encode only the sub-sample of the mp3 file that you're interested in merging with captured audio data.
NAudio has, AFAIK, no WP8 support. I believe that they're currently working on Windows Store App support.
You would need to use WASAPI - which is a native-only API - or the Microsoft.XNA.Audio.Microphone-class to capture data.
I am trying to write a mp3 player using HTML 5 benefits. Play local file, until now, seems ok. Im writing sample codes based on these example : http://antimatter15.github.com/player/player.html
Here's the thing : I have to get the reference of each mp3 file. I want to get all this reference and save on database for when the client access the website i show this playlists. The problem is : doing in that way I mentioned before every time that client close/open browser the blob reference to file is not valid anymore. Iam looking for FileSystem API, that allows to save data into sandbox section. So, data could be cleaned every time users wanted and im still cant save mp3 references on my server database. Could you guys give me sugestions? The real thing is just save a reference from mp3 local file to allow my user create a playlist and every time that he access the web page he could see that playlists.
Thanks in advance,

I doubt this reference(or "object URLs") persistence thing is intentionally unsupported by the browsers. Otherwise you could access the user's filesystem without his awareness. This could be a security problem.
As quoted at here:
Each time you call window.URL.createObjectURL() , a unique object URL is created, even if you've created an object URL for that file already.
Well, i am recording the voice from heaphone and the sound data is stored in ByteArray at runtime, now can i stored as mp3 ??
i want to save as mp3 file on the client system.. For that, i think i have to use air application.. Am i right?
I found this link where someone used Alchemy to convert to MP3.
