I am trying to make a simple application which will store the sound said by user , say on click of record button and will play it back to him/her , say on click of play button.
Can anyone suggest me some appropriate way to do this ??
Thanks,
Miraaj
You can use QuickTime Kit's capture APIs to record a movie of the audio, and QTMovie (from the same framework) to convert it to a more conventional format for audio files and to play back both the intermediate file and the converted file.
There used to be a QuickTime Kit Programming Guide, but it didn't cover capturing and is now gone from developer.apple.com. You should file a bug against the docs.
This answer will work in a Cocoa (Mac) app. If you meant to ask about the iPhone, you should re-tag your question, as the solution will be completely different for a Cocoa app vs. a Cocoa Touch (iPhone) app.
I used direct sound to create an entire internet phone application a few years ago. Your question is far simpler, you won't have to deal with the circular buffer as critically. Direct sound is pretty main stream and you can find a lot of help with it in forums, and it's free!

I tired to googling that how share videos form camera roll in windows phone 8 like in Nokia video upload and facebook app. I used to try this
http://msdn.microsoft.com/en-us/library/windowsphone/develop/ff967563(v=vs.105).aspx
Only share picture but I want to share only videos for my app e.g. when my app show in list when share a video by camera roll of windows phone in sharing
To quote the link you included in your question:
Note that this extensibility is only available when the photo is a JPG
file.
And from my experience, I can confirm that it is not possible to register your app as a share target for a video file.
In other words, if a user tries to share a video from the camera roll or another app, there is no way to make your app appear as one of the options in that list.
Did you try using the share media task function?
Check this article out from the msdn :

You can use MediaLibrary and there is already an answer for your question in this link. As said, there is no way to select existing sound media and video files through default choosers. Thank you.
I m developing an app which can record audio stream.
I want to know that is it possible to record that audio in background, i,e when the application is in deactivated mode?
I have already tried to do that in many different ways,but its not helping out.
Please suggest me some way to do such...
Thank you.
As mentioned in the comments, it's not possible to record in the background.
Your app must be running in the foreground for it to be able to record audio using the microphone. For an overview of all the audio recording options, please refer to this tutorial on the Nokia Developer Wiki.
Also, an app will not run when the phone is locked - it is suspended. So if your app was recording, it would stop when the phone is locked. You can change this behaviour with IdleDetectionMode.Disabled which means your app keeps running even though the phone is locked.
Haven't implemented it before, but classifying it as a VOIP app could be the way to go:

Please see: Is there a way I can capture my iPhone screen as a video?
This post describes many ways to capture video. It looks like there isn't a completely intuitive way to record the video, but this post lists some of the options others have used for their applications.
I want to write a basic app so I can upload some images to my personal server and as the CMD+Shift+4 Screen capture method apple offers doesn't let you upload your images I thought I would start from scratch... I've looked around quite a lot on how to make something what lets me grab a selection of my screen (like the crosshair apple offer) and can't find any samples/pointers however I've seen other tools such as gyazo use the exact same capture system apple offer :S... Is it some sort of framework I can access in Xcode or something?
If anyone knows how its done I would be very grateful.
Thanks
Liam
You can just run screencapture(1) and capture to a temporary file location which your app then reads.
I'm working with the iPhone 3.0 SDK (bit of a novice really), and I have set up an Interface Builder View with several UIButtons in it. I also have several sound files in the Xcode project.
I have searched for this and none of the solutions seem to work for me. Does anyone know how to make a short sound play once upon pressing a button?
Sorry about the simplistic question, but Apple's avTouch doesn't build on my Xcode.
Thanks
For the most basic needs, the AVAudioPlayer class will work. It has the simplest interface on the iPhone SDK and is best suited for what you're describing.
If you need lower latency or multiple sounds at once, then your choice is between OpenAL or Core Audio. See the oalTouch example for OpenAL use.
