Play sounds in iPhone SDK?

Question

Does anyone have a snippet that uses an AudioToolBox structure that can be used to play short sound? I would appreciate it if you share it with me and the rest of the community. Wherever I looked, it doesn't seem too clear with their code.

Thanks!

Answer 1

Here is a simple example of using AVAudioPlayer:

-(void)PlayClick { NSURL* musicFile = [NSURL fileURLWithPath:[[NSBundle mainBundle] pathForResource:@"click" ofType:@"caf"]]; AVAudioPlayer *click = [[AVAudioPlayer alloc] initWithContentsOfURL:musicFile error:nil]; [click play]; [click release]; } 

This assumes that the main package has a file named "click.caf". Since I play a lot in this sound, I actually continue to play it later, rather than releasing it.

Answer 2

I wrote a simple Objective-C wrapper around AudioServicesPlaySystemSound and friends:

 #import <AudioToolbox/AudioToolbox.h> /* Trivial wrapper around system sound as provided by Audio Services. Don't forget to add the Audio Toolbox framework. */ @interface Sound : NSObject { SystemSoundID handle; } // Path is relative to the resources dir. - (id) initWithPath: (NSString*) path; - (void) play; @end @implementation Sound - (id) initWithPath: (NSString*) path { [super init]; NSString *resourceDir = [[NSBundle mainBundle] resourcePath]; NSString *fullPath = [resourceDir stringByAppendingPathComponent:path]; NSURL *url = [NSURL fileURLWithPath:fullPath]; OSStatus errcode = AudioServicesCreateSystemSoundID((CFURLRef) url, &handle); NSAssert1(errcode == 0, @"Failed to load sound: %@", path); return self; } - (void) dealloc { AudioServicesDisposeSystemSoundID(handle); [super dealloc]; } - (void) play { AudioServicesPlaySystemSound(handle); } @end 

Lives here . For other sound parameters see this question .

AudioService sounds are independent of the device volume controller. Even if the phone is in silent mode, sound signals will play. These sounds can only be muted by tapping Settings → Sounds → Rings and alerts .

Custom system sounds can be played with the following code:

 CFBundleRef mainbundle = CFBundleGetMainBundle(); CFURLRef soundFileURLRef = CFBundleCopyResourceURL(mainbundle, CFSTR("tap"), CFSTR("aif"), NULL); AudioServicesCreateSystemSoundID(soundFileURLRef, &soundFileObject); 

Call vibration in iPhone

 AudioServicesPlaySystemSound(kSystemSoundID_Vibrate); 

Reproduction of the built-in sounds of the system.

 AudioServicesPlaySystemSound(1100);
