I want to play BGM. The below code plays BGM on only 64bit mode. What should I do?
- (void)playBgmLoop
{
NSString *path = [[NSBundle mainBundle] pathForResource:#"aikatsu" ofType:#"mp3"];
NSURL *url = [NSURL fileURLWithPath:path];
audio = [[AVAudioPlayer alloc] initWithContentsOfURL:url error:nil];
// Infinite loop
audio.numberOfLoops = -1;
[audio play];
}
#end
Thank you for your help.

I have a timer that plays a sound when time reaches 0, but now I can't understand how to fire the event in order to play the sound if the app is in background mode or the screen is locked, What I found searching on the web was to set "UIBackgroundModes" in my .plist file, and add "audio" as array member.
UIBackgroundModes Array
Item0 String audio
Then add in the app delegate the following code:
NSError *setCategoryErr = nil;
NSError *activationErr = nil;
[[AVAudioSession sharedInstance] setCategory: AVAudioSessionCategoryPlayback error:&setCategoryErr];
[[AVAudioSession sharedInstance] setActive:YES error:&activationErr];
But the sound doesn't get played.. So I was wondering if it's possible to do something like this or I should change method
EDIT:
I imported:
#import <AudioToolbox/AudioToolbox.h>
#import <AVFoundation/AVFoundation.h>
And this is the code I use to create the sound:
AVAudioPlayer *player;
NSString *soundFilePath = [NSString stringWithFormat:#"%#/clock.mp3",
[[NSBundle mainBundle] resourcePath]];
NSURL *soundFileURL = [NSURL fileURLWithPath:soundFilePath];
player = [[AVAudioPlayer alloc] initWithContentsOfURL:soundFileURL
error:nil];
player.numberOfLoops = -1;
dispatch_async(dispatch_get_main_queue(), ^{
[player prepareToPlay];
});
Then to play it:
[player play];
I have just a snippet of Swift code but it should be easy to convert it to Obj-C
Try to use AVPlayerItem init with URL and then set AVPlayer init with PlayerItem
let assetUrl = self.nowPlayingItem!.associatedItem!.valueForProperty(MPMediaItemPropertyAssetURL) as! NSURL
let playerItem = AVPlayerItem(URL: assetUrl)
if let player = self.player {
player.replaceCurrentItemWithPlayerItem(playerItem)
} else {
self.player = AVPlayer(playerItem: playerItem)
}
self.player!.play()
and for this line of code:
NSString *soundFilePath = [NSString stringWithFormat:#"%#/clock.mp3",
[[NSBundle mainBundle] resourcePath]];
Have you tried:
[[NSBundle mainBundle] URLForResource:#"song" withExtension:#"mp3"];
// Create a new player item
NSURL *assetUrl = [nowPlayingItem valueForProperty:MPMediaItemPropertyAssetURL];
AVPlayerItem *playerItem = [AVPlayerItem playerItemWithURL:assetUrl];
// Either create a player or replace it
if (self.player) {
[self.player replaceCurrentItemWithPlayerItem:playerItem];
} else {
self.player = [AVPlayer playerWithPlayerItem:playerItem];
}
nowPlayingItem is here a MPMediaItem but just replace NSURL *assetUrl = [nowPlayingItem valueForProperty:MPMediaItemPropertyAssetURL]; by NSURL *assetUrl =[[NSBundle mainBundle] URLForResource:#"song" withExtension:#"mp3"];
I'm trying to play an audio file when a button is tapped.
If I step through my code it works, but if I just tap on the button no sound is played.
Here is my code:
[[AVAudioSession sharedInstance] setCategory:AVAudioSessionCategoryPlayback error:nil];
AVAudioPlayer * player;
NSString * path = [[NSBundle mainBundle] pathForResource:#"soundOne" ofType:#"mp3"];
NSURL * url = [NSURL fileURLWithPath:path];
player = [[AVAudioPlayer alloc] initWithContentsOfURL:url error:nil];
[player play];
Is this the appropriate way to play audio? Nothing is being flagged as being deprecated.
I also see this message in the debugger:
AudioQueue: request to trim 0 + 2690 = 2690 frames from buffer containing 1152 frames
EDIT:
This code works.
NSString *filePath = [[NSBundle mainBundle] pathForResource:#"soundOne"
ofType:#"mp3"];
NSURL *fileURL = [[NSURL alloc] initFileURLWithPath:filePath];
self.audioPlayer = [[AVAudioPlayer alloc]
initWithContentsOfURL:fileURL error:nil];
[self.audioPlayer prepareToPlay];
self.audioPlayer.currentTime = 0;
[self.audioPlayer play];
How can I play audio with the mute button on?
Here is the code I have tried for this:
CFStringRef state;
UInt32 propertySize = sizeof(CFStringRef);
OSStatus audioStatus = AudioSessionGetProperty(kAudioSessionProperty_AudioRoute, &propertySize, &state);
if (audioStatus == kAudioSessionNoError) {
//NSLog(#"audio route: %#", state);
return (CFStringGetLength(state) <+ 0);
}
return NO;
Stick this before you call play:
[[AVAudioSession sharedInstance] setCategory:AVAudioSessionCategoryPlayback error:&error];
[[AVAudioSession sharedInstance] setActive:YES error:&error];
That should do it.
I want to implement a player that plays sounds and/or music. I have these two methods:
-(void)playSound:(int)soundIndex
{
NSURL *url = [NSURL fileURLWithPath:[[NSBundle mainBundle] pathForResource:[SoundFxFilenameArray objectAtIndex:soundIndex] ofType:#"mp3"]];
if(FxPlayer)
{
[FxPlayer release];
FxPlayer = nil;
}
[[AVAudioSession sharedInstance] setCategory:AVAudioSessionCategorySoloAmbient error:nil];
FxPlayer = [[AVAudioPlayer alloc] initWithContentsOfURL:url error:nil];
[FxPlayer play];
}
-(void)playMusic:(NSString *)filename
{
NSURL *url = [NSURL URLWithString:[[NSBundle mainBundle] pathForResource:filename ofType:#"mp3"]];
if(MusicPlayer)
{
[MusicPlayer release];
MusicPlayer = nil;
}
MusicPlayer = [[AVAudioPlayer alloc] initWithContentsOfURL:url error:nil];
[MusicPlayer play];
}
Now, [[SoundPlayer sharedManager] playSound:FXIndex_Default] works just fine. When I try to play music though, [[SoundPlayer sharedManager] playMusic:#"music_file_name_here" just doesn't do anything. Note that both the sound file and the music file are of the same format (mp3).
Also, the "sharedInstance" is because I implemented the singleton pattern for this audio player.
Any pointers or ideas on what is so wrong in my code so that I can play sounds but not music?
Use fileURLWithPath instead of URLWithString in playMusic:
NSURL *url = [NSURL fileURLWithPath:[[NSBundle mainBundle] pathForResource:filename ofType:#"mp3"]];
URLWithString expects a complete URL such as "file://path/to/file.mp3" as argument, fileURLWithPath expects just a file path.
I need to play some system sound when users click button in my application which is running on iPad. How to implement it in iOS?
If you want to play a short sound (shorter than 30 sec), you can do it easily like this:
Note: You'll have to add AudioToolbox framework and import it (#import <AudioToolbox/AudioToolbox.h>)
SystemSoundID mySSID;
NSString *path = [[NSBundle mainBundle] pathForResource:#"beep" ofType:#"wav"];
AudioServicesCreateSystemSoundID((CFURLRef)[NSURL fileURLWithPath: path], &mySSID);
AudioServicesPlaySystemSound(mySSID);
Also note that the file can be:
No longer than 30 seconds in duration
In linear PCM or IMA4 (IMA/ADPCM) format
Packaged in a .caf, .aif, or .wav file
You should use AVAudioPlayer.
There's a great tutorial here on using AVAudioPlayer to play sounds. A very simple example of it's use:
NSURL *url = [NSURL fileURLWithPath:[NSString stringWithFormat:#"%#/audiofile.mp3",dataPath];
NSError *error;
audioPlayer = [[AVAudioPlayer alloc] initWithContentsOfURL:url error:&error];
if (audioPlayer == nil)
NSLog([error description]);
else
[audioPlayer play];
NSString *path = [[NSBundle mainBundle] pathForResource:#"gorilla 2" ofType:#"mp3"];
AVAudioPlayer* theAudio=[[AVAudioPlayer alloc] initWithContentsOfURL:[NSURL fileURLWithPath:path] error:NULL];
theAudio.delegate=self;
[theAudio play];
I have this code to play a sound but the first time you play it it takes a good 5 seconds to load...
How can I speed this up?
-(IBAction)playSound{ //play the cricket noise
NSString *soundPath = [[NSBundle mainBundle] pathForResource:#"Cricket_Sound" ofType:#"mp3"];
audioPlayer =[[AVAudioPlayer alloc] initWithContentsOfURL:[NSURL fileURLWithPath:soundPath] error:NULL];
audioPlayer.delegate = self;
[audioPlayer prepareToPlay];
audioPlayer.numberOfLoops = 0;
[audioPlayer play];
}
You can try by putting the following section of your code in viewDidLoad so that the audioPlayer instance is ready to play before it is asked to actually play the audio:
NSString *soundPath = [[NSBundle mainBundle] pathForResource:#"Cricket_Sound" ofType:#"mp3"];
audioPlayer =[[AVAudioPlayer alloc] initWithContentsOfURL:[NSURL fileURLWithPath:soundPath] error:NULL];
audioPlayer.delegate = self;
[audioPlayer prepareToPlay];
audioPlayer.numberOfLoops = 0;
