I'm new on Swift. I write because I want to ask a question. Me and my friend we are developing an audio player, but we have a problem. The player also works in background and remote controls from the lockscreen and the control center work, but if music is interrupted by one of these two controls, the play/pause button of our player is not updated with the correct icon. My question is, how can I make

I run the following code on simulator and I don't get any sound: NSString *soundPath = [[NSBundle mainBundle] pathForResource:@"pageflip" ofType:@"mp3"]; NSURL *soundUrl = [NSURL fileURLWithPath:soundPath]; AudioServicesCreateSystemSoundID((__bridge CFURLRef) soundUrl, &_soundEffect); AudioServicesPlaySystemSound(_soundEffect); The code has been successfully tested on xCode 5 and iOS 7. Libraries imported as required. I've logged the soundPath and it returns the correct location on the filesystem. Has anyone experienced a similar issue? This is an issue with the simulator. On a device it'll

I am creating a SpriteKit Game with background music looping. The problem is that the music is too loud. How do I lower the volume? Here is the code I used to set up the music var backGroundMusic = AVAudioPlayer() var bgMusicUrl:NSURL = NSBundle.mainBundle().URLForResource("BackGround", withExtension: "wav") backGroundMusic = AVAudioPlayer(contentsOfURL:bgMusicUrl, error: nil) backGroundMusic.numberOfLoops = (-1) backGroundMusic.prepareToPlay() backGroundMusic.play() Have you tried this? backGroundMusic.volume = 0.5 Volume goes from 0.0 to 1.0 (full volume). https://developer.apple.com/library

I'm new to the iPhone-Development. I want to play a Sound when an UIButton is tapped. I tried the following: ViewController.h: @interface JahrenzeitenViewController : UIViewController <AVAudioPlayerDelegate> { UIButton *button_PlaySound; AVAudioPlayer *audioPlayer; } @property (nonatomic, retain) IBOutlet UIButton *button_PlaySound; ViewController.m - (IBAction)playSound { //[audioPlayer release]; //audioPlayer = nil; NSString *audioFilePath = [[NSBundle mainBundle] pathForResource:@"test" ofType:@"wav"]; NSURL *audioFileURL = [NSURL fileURLWithPath:audioFilePath]; NSError *error = nil;

Statement of Problem: I have a collection of sound effects in my app stored as .m4a files (AAC format, 48 KHz, 16-bit) that I want to play at a variety of speeds and pitches, without having to pre-generate all the variants as separate files. Although the .rate property of an AVAudioPlayer object can alter playback speed, it always maintains the original pitch, which is not what I want. Instead, I simply want to play the sound sample faster or slower and have the pitch go up or down to match — just like speeding up or slowing down an old-fashioned reel-to-reel tape recorder. In other words, I

I have an App that records and then plays back an audio file. Currently the audio playback is playing through the earpiece speaker. Could someone tell me how Swift would handle coding this to force the audio out the loud speaker instead? Below is a one of the instances I'm using to play the audio file: @IBAction func playAudioVader(sender: UIButton) { playAudioWithVariablePitch(-1000) } func playAudioWithVariablePitch(pitch: Float){ audioPlayer.stop() audioEngine.stop() audioEngine.reset() var audioPlayerNode = AVAudioPlayerNode() audioEngine.attachNode(audioPlayerNode) var changePitchEffect =
