I had code in a old sdk 3.0 project of mine that is not working with the new sdk. I have copied the code in a very simple project (just a uivue project and I put the sound code in onload) to make sure nothing else I did is messing it up.
I'm getting a error code -46, Domain NSOSStatusErrorDomain
code
- (void)viewDidLoad
{
NSURL *url = [NSURL fileURLWithPath:[NSString stringWithFormat:#"EvilDrop-2.mp3",
[[NSBundle mainBundle] resourcePath]]];
NSError *error;
audioPlayer = [[AVAudioPlayer alloc] initWithContentsOfURL:url error:&error];
audioPlayer.volume=1.0;
audioPlayer.numberOfLoops= 0;
[audioPlayer play];
audioPlayer.delegate = self;
}
That's because you're not using -[NSString stringWithFormat: correctly. However, you don't need that method.
Try this code:
NSURL *myURL;
myURL = [[NSBundle mainBundle]
URLForResource:#"MyFile"
withExtension:#"mp3"];

I am developing an iPhone application.In this app i am using AVAudioPlayer for playing audio.
This is my code for playing the sound.
NSString* resourcePath = [[NSBundle mainBundle] resourcePath];
resourcePath = [resourcePath stringByAppendingString:#"/sound.mp3"];
NSError* err;
player_ = [[AVAudioPlayer alloc] initWithContentsOfURL:
[NSURL fileURLWithPath:resourcePath] error:&err];
if( err )
{
}
else
{
[player_ prepareToPlay];
[player_ play];
int playingLoops = 0;
player_.numberOfLoops = playingLoops;
}
It is woking fine on iphone devices except iPhone5.While i run the app on iPhone 5 i get following error then app crashes.
2012-11-26 09:02:28.484 test[728:1dd03] <0xb0081000> Error '!obj' trying to fetch default input device's sample rate
2012-11-26 09:02:28.484 test[728:1dd03] <0xb0081000> Error getting audio input device sample rate: '!obj'
2012-11-26 09:02:28.494 test[728:1dd03] <0xb0081000> AQMEIOManager::FindIOUnit: error '!dev'
I was also facing same problem giving the same error. when try to solve this problem i notice that there is no problem in code. we need to update media player or install flash player and it's work fine.
You have to add AVAudioPlayerDelegate to your .h file and following code to your .m file
NSString* resourcePath =[[NSBundle mainBundle]pathForResource:#"sound" ofType:#"mp3"];
NSError* err;
AVAudioPlayer *audioplayer =[[AVAudioPlayer alloc]initWithContentsOfURL:[NSURL fileURLWithPath: resourcePath] error:&err];
audioplayer.delegate=self;
if( err )
{
NSLog(#"%#",err);
}
else
{
[audioplayer prepareToPlay];
[audioplayer play];
}
This code is working for me and accept the answer if it is working.
Anbu, try below code.At my end it's working fine.
NSURL *url = [NSURL fileURLWithPath:[NSString stringWithFormat:#"%#/audiofile.mp3", [[NSBundle mainBundle] resourcePath]]];
NSLog(#"File path is:->%#",[NSString stringWithFormat:#"%#/audiofile.mp3", [[NSBundle mainBundle] resourcePath]]);
NSFileManager* manager;
manager = [NSFileManager defaultManager];
if([manager fileExistsAtPath:[NSString stringWithFormat:#"%#/audiofile.mp3", [[NSBundle mainBundle] resourcePath]]])
{
printf("file Exists...\n\n");
}
else
printf("File not exist...\n\n");
NSError *er;
audioPlayer = [[AVAudioPlayer alloc] initWithContentsOfURL:url error:&error];
audioPlayer.numberOfLoops = -1;
if (audioPlayer == nil)
NSLog([er description]);
else
[audioPlayer play];
In any concern, let me know. And, also please check your console for the full path and for file exist or not.
I currently have this code that works. I have two questions.
How do I set the directory to "Supporting Files"?
How do I use a variable in the file name? I need it to pull an mp3 of any animal based on a variable.
- (void)playAnimal{
NSURL *url = [NSURL fileURLWithPath:[NSString stringWithFormat:#"%#/Sheep.mp3", [[NSBundle mainBundle] resourcePath]]];
NSError *error;
audioPlayer = [[AVAudioPlayer alloc] initWithContentsOfURL:url error:&error];
audioPlayer.numberOfLoops = 0;
if (audioPlayer == nil)
NSLog([error description]);
else
[audioPlayer play];
}
I'm very new to Objective-C, so a lot of syntax things are new to me as well as general methods. Thanks for your patience!
Use the following:
NSString *path = [[NSBundle mainBundle] pathForResource:#"Sheep" ofType:#"mp3"]];
NSURL *url = [NSURL fileURLWithPath:path];
When your resources are copied to the bundle, they do not retain their directory structure. Just identify the resource by name and it will find the path for it.
Just as an FYI, the following works, as well:
NSString *path = [[NSBundle mainBundle] pathForResource:#"Sheep.mp3" ofType:#""]];
NSURL *url = [NSURL fileURLWithPath:path];
This may be useful if you have a set of resources logically grouped together in a plist and you are programmatically reading those out. For example:
// reference to a dictionary with the entry 'Sheep.mp3'
NSString *resourceName = [dictionary objectForKey:item1];
NSString *path = [[NSBundle mainBundle] pathForResource:resourceName ofType:#""]];
NSURL *url = [NSURL fileURLWithPath:path];
So I'm trying to test out the audio player on the iPhone, and I went off Troy Brant's iOS book. I have the Core Audio, Core Foundation, AudioToolbox, and AVFoundation frameworks added to my project. The error message I get is in the subject field. I read like 20 pages of Google search results before resorting to asking here! /sigh. Thanks if you can help. Here's my code, pretty much verbatim out of his book:
NSString *soundFilePath = [[NSBundle mainBundle] pathForResource:#"Yonah" ofType:#"caf"];
NSLog(#"%#", soundFilePath);
NSURL *fileURL = [NSURL URLWithString:soundFilePath];
NSError *error;
audioPlayer = [[AVAudioPlayer alloc] initWithContentsOfURL:fileURL error:&error];
if (!error)
{
audioPlayer.delegate = self;
//audioPlayer.numberOfLoops = -1;
[audioPlayer play];
}
else
{
NSLog(#"Error loading audio clip: %#", [error localizedDescription]);
}
EDIT: Holy Shinto. I figured out what it was. I changed
NSURL *fileURL = [NSURL URLWithString:soundFilePath];
to
NSURL *fileURL = [NSURL fileURLWithPath:soundFilePath];
to the latter and I was getting a weird error, weirder than the one in the subject BUT I googled that and I changed my OS input device from my webcam to my internal microphone and guess what, it worked under the fileURLWithPath method. I'll be. Damned.
try this one- convert your url into NSdata
NSString* resourcePath = self.audioStr; //your url
NSData *_objectData = [NSData dataWithContentsOfURL:[NSURL URLWithString:resourcePath]];
NSError *error = [[NSError alloc] init];
NSLog(#"url is %#",resourcePath);
audioPlayer = [[AVAudioPlayer alloc] initWithData:_objectData error:&error];
audioPlayer.numberOfLoops = 0;
if (error)
{
NSLog(#"Error in audioPlayer: %#",
[error localizedDescription]);
} else {
audioPlayer.delegate = self;
[audioPlayer prepareToPlay];
}`
Try to read the audio file with something like this:
audioPlayer_ = [[AVAudioPlayer alloc] initWithContentsOfURL:
[NSURL fileURLWithPath:[NSString stringWithString:soundFilePath_]]
error:&error];
I want to play mp3 file placed in resources as code is given below,
NSString *st=#"alarm_1.mp3";
NSLog(st);
NSURL* musicFile = [NSURL fileURLWithPath:st];
AVAudioPlayer *click = [[AVAudioPlayer alloc] initWithContentsOfURL:musicFile error:nil];
//AVAudioPlayer *click1=[[AVAudioPlayer alloc]initWithContentsOfURL:[NSURL URLWithString:#"alarm_1.mp3"]];
[click prepareToPlay];
[click play];
[click release];
but unfortunately i cant hear the sound
please help
I don't think your file name is right. Try this syntax:
NSURL *clickURL = [NSURL fileURLWithPath:[NSString stringWithFormat:#"%#/alarm_1.mp3", [[NSBundle mainBundle] resourcePath]]];
AVAudioPlayer *audioPlayer = [[AVAudioPlayer alloc]initWithContentsOfURL:clickURL error:nil];
I had a similar problem due to ARC. Instead of defining the AVAudioPlayer in the same method you are using it, you should should have an instance variable somewhere else, such as the UIViewController. This way ARC doesn't auto release this object and audio can play.
NSURL *url = [NSURL fileURLWithPath:[NSString stringWithFormat:#"%#/alarm_1.mp3", [[NSBundle mainBundle] resourcePath]]];
NSError *error;
AVAudioPlayer *audioPlayer = [[AVAudioPlayer alloc] initWithContentsOfURL:url error:&error];
audioPlayer.numberOfLoops = -1;
[audioPlayer play];
This is answer
My Problem is the following. I got this code and i guess a corrupt NSURL since the AVAudioPlayer is nil after initializing:
NSString *dummyURLString = #"http://a825.phobos.apple.com/us/r2000/005/Music/d8/a8/d2/mzi.jelhjoev.aac.p.m4p";
NSError *error;
NSURL *url = [NSURL URLWithString:dummyURLString];
AVAudioPlayer *player = [[AVAudioPlayer alloc] initWithContentsOfURL:url error:&error];
[player play];
Any suggestions what is going wrong here?
The &error shows this:
Error Domain=NSOSStatusErrorDomain Code=-43 "Operation could not be completed. (OSStatus error -43.)"
AVAudioPlayer only works with local URL's. It must be a File URL (file://)
See Apple's Technical Q&A QA1634
I tried this first but got error 2003334207:
NSData *soundData = [NSData dataWithContentsOfURL:URL];
AVAudioPlayer *player = [[AVAudioPlayer alloc] initWithData:soundData error:&error];
Seems that AVAudioPlayer really wants a file. So I put the data into a file first:
NSURL *url = [NSURL URLWithString:#"http://a825.phobos.apple.com/us/r2000/005/Music/d8/a8/d2/mzi.jelhjoev.aac.p.m4p"];
NSData *soundData = [NSData dataWithContentsOfURL:url];
NSString *filePath = [[NSSearchPathForDirectoriesInDomains(NSDocumentDirectory,
NSUserDomainMask, YES) objectAtIndex:0]
stringByAppendingPathComponent:#"sound.caf"];
[soundData writeToFile:filePath atomically:YES];
player = [[AVAudioPlayer alloc] initWithContentsOfURL:[NSURL
fileURLWithPath:filePath] error:NULL];
NSLog(#"error %#", error);
Instead of using the AVAudioPlayer you can use the AVPlayer. The AVPlayer works as well with remote URLs
