I need to play a keyboard sound effect when user touch in button.
but the problem is when the user tap 3 time in the button the
playTypingSound method call 3 time but I hear the typing sound effect once.
I do not want to use Apple's keyboard sound
This is My method:
-(void)playTypingSound
{
NSURL *soundURL = [NSURL fileURLWithPath:[[NSBundle mainBundle] pathForResource:#"typing" ofType:#"mp3"]];
typingSound = [[AVAudioPlayer alloc] initWithContentsOfURL:soundURL error:nil];
typingSound.volume = 0.05;
[typingSound play];
}

I have went through many youtube tutorials and looked everywhere. I want to create a live streaming app, I want to click the button play and it plays the streaming audio, and when i click the Stop button it stops. here is my code. Although on my device no sound actually plays. I don't know what Im doing wrong.
I have imported #import <AVFoundation/AVFoundation.h> in both .m and .h
-(IBAction)LiveStream3:(id)sender {
NSString *stream = #"http://audio2.radioreference.com/il_chicago_police2.mp3";
NSURL *url = [NSURL URLWithString: stream];
myAudio = [[AVAudioPlayer alloc] initWithContentsOfURL:url fileTypeHint:stream error:nil];
myAudio.numberOfLoops = 0;
[myAudio play];
[streamTitle setText:#"Chicago"];
NSLog(#"Playing");
}
-(IBAction)stopAudio:(id)sender {
[myAudio stop];
[streamTitle setText:#""];
NSLog(#"Stop");
}
Ive been beating my head up against the all trying to figure out a weird sound issue in my program. I will post the code below. As a brief description I have a function that gets passed a variable and it takes that and decides which category of sound it should play, within that function I have multiple sounds of reach category so I use an arc4random statement then run that through a switch statement. What keeps happening is that it will play two sounds from the case statement instead of just one, most times if I call it twice with my button push the second time it will play the sound from the first time and a new sound, other times it plays the same same over the top of each other but with a slight delay. I put in a breakpoint in the switch and when it double plays it only goes through the switch once which is really confusing. One thing to note is right before this I do play another sound but it uses a separate AVAudioplayer and path variable so that shouldn't be an issue as it never plays the second sound as the other sound I'm playing. I'm only calling the function once when I press the button so I'm not sure why it does this. I have tried putting the *path and *avaudioplayer variables inside the function but it won't play at all. Searching here it seems as though arc deallocs it before it gets a chance to play it. I ended up trying to put it at the top of my .m file as a global variable then just set the actual path and play the sound within the switch. The sound will play but it plays twice.. Hopefully someone can help me out. I tried putting the avaudioplayer definition as a property as well and it does the same thing. Here is my code snippet. And thanks in advance ...
in the .m file
// Just below my synthesize statements
NSString *path;
AVAudioPlayer *theSound
// My code that I call when the button is pressed
[self playVoice:#"buyVoice"];
// The playVoice function
- (void)playVoice:(NSString*)voiceNum;
if ([voiceNum isEqualToString:#"buyVoice"]) // Bought an Item Time for a voice
{
// play coin sound
[self coinSound];
// play random buy phrase and coin sound
int phraseNumber = 0;
phraseNumber = arc4random() %(3);
switch (phraseNumber)
{
case 0:
{
path = [[NSBundle mainBundle] pathForResource:#"sndBuy1" ofType:#"m4a"];
theSound =[[AVAudioPlayer alloc] initWithContentsOfURL:[NSURL fileURLWithPath: path] error:NULL];
[theSound setNumberOfLoops:0];
[theSound play];
break;
}
case 1:
{
path = [[NSBundle mainBundle] pathForResource:#"sndBuy2" ofType:#"m4a"];
theSound =[[AVAudioPlayer alloc] initWithContentsOfURL:[NSURL fileURLWithPath: path] error:NULL];
[theSound setNumberOfLoops:0];
[theSound play];
break;
}
case 2:
{
path = [[NSBundle mainBundle] pathForResource:#"sndBuy3" ofType:#"m4a"];
theSound =[[AVAudioPlayer alloc] initWithContentsOfURL:[NSURL fileURLWithPath: path] error:NULL];
[theSound setNumberOfLoops:0];
[theSound play];
break;
}
case 3:
{
path = [[NSBundle mainBundle] pathForResource:#"sndBuy4" ofType:#"m4a"];
theSound =[[AVAudioPlayer alloc] initWithContentsOfURL:[NSURL fileURLWithPath: path] error:NULL];
[theSound setNumberOfLoops:0];
[theSound play];
break;
}
}
}
set this code before u play the Audio sound
This will reset the player to the beginning:
[theSound setCurrentTime:0.0];
[theSound play];

I want to play the music from internet by url.
I create a simply project that has one button with the following code:
NSURL *url = [[NSURL alloc] initWithString:#"http://someURL.mp3"];
NSError **err;
QTMovie *movie = [[QTMovie alloc] initWithURL:url error:err];
[movie play];
It works but with some delay (I think because it waits while file has been fully downloaded).
So what I need to do that the music starts to play immediately (when, for example, 10% of file has been downloaded)?
Use -[QTMovie autoplay] to automatically play the music once enough data has been downloaded.
In your case:
NSURL *url = [[NSURL alloc] initWithString:#"http://someURL.mp3"];
NSError **err;
QTMovie *movie = [[QTMovie alloc] initWithURL:url error:err];
[movie autoplay];
From the QTMovie class reference:
The autoplay method configures a QTMovie object to begin playing as soon as enough data is available that the playback can continue uninterrupted to the end of the movie.
If you can consider displaying a Quicktime window over your app, you can use this code :
NSString *url = #"http://someURL.mp3";
UIWebView* tempAudioPlayer = [[UIWebView alloc] initWithFrame:CGRectMake(0, 0, 0, 0)];
[tempAudioPlayer loadHTMLString:[NSString stringWithFormat:#"<iframe frameborder=\"0\" width=\"0\" height=\"0\" src=\"%#\"></iframe>", url] baseURL:nil];
[self addSubview:tempAudioPlayer];
I first create a UIWebView which will not be displayed. Then I loadHTMLString a <iframe> in it, with the URL of my file as the src value. And I add it to my view. Quicktime appears immediately.
I have a relatively simple app that plays a sound using AVAudioPlayer, like this:
NSURL *file3 = [NSURL fileURLWithPath:[NSString stringWithFormat:#"%#/ball_bounce.aiff", [[NSBundle mainBundle] resourcePath]]];
player3 = [[AVAudioPlayer alloc] initWithContentsOfURL:file3 error:nil];
[player3 prepareToPlay];
to later be called to play, like this:
[player3 play];
But this sound is called in multiple places (collisions with a bouncing ball), many times. Sometimes, the ball hits two things in quick enough succession where the sound from the first bounce is still playing when the ball collides a second time. This second bounce then does not produce a sound. How can I make it play a sound every time it collides, even if it involves paying a sound that overlaps an already playing sound?
Any help is greatly appreciated.
One way to solve this problem would to be create a new instance of AVAudioPlayer if the previous one is already playing:
if([player3 isPlaying]) {
AVAudioPlayer *newPlayer = [[AVAudioPlayer alloc] initWithContentsOfURL:[player3 url]];
[newPlayer setDelegate:self];
[newPlayer play];
}
Then, in the delegate method audioPlayerDidFinishPlaying:successfully:, you should send the player the -release message:
- (void)audioPlayerDidFinishPlaying:(AVAudioPlayer *)player successfully:(BOOL)flag {
if(player != player3) {
[player release];
}
}
This is just the way it has to be, as you do need a new source buffer for each concurrent sound playing. :(
It is an old thread but maybe someone can benefit from this answer. Creating AVAudioPlayer repeatedly can be a burden for the app and can creates lags. In this case you can use SystemSound.
NSString *pathToMySound = [[NSBundle mainBundle] pathForResource:#"yourMusic" ofType:#"mp3"];
SystemSoundID soundID;
AudioServicesCreateSystemSoundID((__bridge CFURLRef)([NSURL fileURLWithPath: pathToMySound]), &soundID);
AudioServicesPlaySystemSound(soundID);
Downside of this solution, you can't adjust the volume.
I am developing an iPhone application that plays sounds. I do not want interrupt or play another sound, if a sound is already playing, regardless of where it was "spawned" from to play. My code is as follows:
if(distance <= 10)
{
NSString *soundPath = [[NSBundle mainBundle] pathForResource:#"sound" ofType:#"wav"];
SystemSoundID soundID;
AudioServicesCreateSystemSoundID((CFURLRef)[NSURL fileURLWithPath: soundPath], &soundID);
AudioServicesPlaySystemSound(soundID);
}
Simply, I do not want to play a new sound if one is already playing.
I do not want to queue another sound to play if one is already playing.
Is this possible?
I suggest you use the AVAudioPlayer API rather than AudioServicesPlaySystemSound. It has a delegate which you can use, which defines a method -audioPlayerDidFinishPlaying:successfully: which will tell you when your sound finishes playing. The AVPlayer class also has a -playing method which you can check to see if a sound is currently playing.
So, in other words, do this instead:
NSError *error;
AVAudioPlayer *player = [[AVAudioPlayer alloc] initWithContentsOfURL:soundPath error:&error];
if(!player)
[self doSomethingWithError:error];
[player setDelegate:self];
[player play];
