please anyone know is there any sample code for beat detection iPhone?.How to implement fft algorithm in iphone to detect music beats?.I see in one forum that apple's sample code auriotouch doing the beat detection, is it correct?.
thanks

Do you really want to do beat detection, or you just want to show output level?
AVAudioPlayer has
- (float)peakPowerForChannel:(NSUInteger)channelNumber;
method which allows you to easily create output level meter by calling it periodically.

If answer is yes, what are the frameworks can I use? I'm planning to do an app which records in slow-motion mode because in normal I just can record to max 60fps. Can I do it with swift or do I need to use objective-c? I would like to capture 240fps with slow-motion.
I get 1920x1080 240 fps in ultrawideanglecamera mode. And get that camera with discoverySession method of swift.

I am developing a iPhone application that needs realtime sound processing. What i would like to archive is to get the sound loudness (from the microphone), compare it with a threshold and do some logic based on the loudness level. Is there any library in iOS that would enable me to do this? Does iOS have any built in function that would give me the current sound loudness level?
Thanks!
This SO question looks like a good place to start (it's close enough to be a dupe, maybe, but I figured I'd answer anyway).

I need to implement creating custom gesture(like Gesture Builder in Android) in my iPhone application. So, is there any good tutorial or sample application?.
Thanks
The best thing is to watch the WWDC sessions on gestures. They're free and available through iTunes if you're a registered developer.

Is there a basic tutorial for the AVFoundation for use with the camera anywhere?
UIImagePicker isn't the right tool for my app and it looks like this is but I'm not sure how to get it going.
I can kind of see how to take a picture using AVCaptureStillImageOutput but I can't see how to display the camera view onto the screen.
Any help is much appreciated.
Thanks
Oliver
If you're a registered Apple developer, session 409 (in the Graphics and Media section) of this year's WWDC is a very good tutorial: http://developer.apple.com/videos/wwdc/2010/
here are more direct links ...

I am working on an app which should allow user to record video on iPhone 3GS.
I was looking into MediaPlayer references but could not find anything there. Can someone give me a head start on the APIs to look for?
You want the UIImagePickerController, which is basically a dialog box that you can show to let the user either take pictures or record video.
