I have a global variable audioPlayer. Every time user click on "Buzz" button, it call this function:
static func playBuzz() {
if audioPlayer == nil {
let url = Bundle.main.path(forResource: "6", ofType: "wav")!
let contentURL = URL.init(fileURLWithPath: url)
do {
audioPlayer = try AVAudioPlayer(contentsOf: contentURL)
audioPlayer.volume = 1.0
} catch {
}
}
print("play buzz ")
DispatchQueue.global().async {
audioPlayer.prepareToPlay()
audioPlayer.play()
}
}
}
But when I call this, it play sound very randomly. Sometimes it play sound, sometimes it don't play sound. How can I resolve this problem?
The answer is when audioPlaying is play, I call play it won't process. My audio player have 1 second duration.
So to fix this, I put more lines:
if audioPlayer.isPlaying {
DispatchQueue.main.asyncAfter(deadline: .now() + 1) { //Make sure to call play() after audioPlayer finish playing.
audioPlayer.prepareToPlay()
audioPlayer.play()
return
}
}

I call the superPlay function to start audio playback a little while later I call the superPlay function again to stop the playback. This does not work though because player.isPlaying is false even knowing the sound is clearly playing in an infinite loop. I have no idea why please help!
func superPlay(timeInterval: TimeInterval, soundName: String) {
do {
alarmSound = soundName
//set up audio session
try AVAudioSession.sharedInstance().setCategory(.playAndRecord, options: [.defaultToSpeaker, .duckOthers])
try AVAudioSession.sharedInstance().setActive(true)
let url = Bundle.main.url(forResource: alarmSound, withExtension: "mp3")
player = try! AVAudioPlayer(contentsOf: url!)
player.numberOfLoops = -1
//Start AVAudioPlayer
print(timeInterval)
print(time)
let playbackDelay = timeInterval // must be ≥ 0
if player.isPlaying {
player.stop()
} else {
player.play(atTime: player.deviceCurrentTime + playbackDelay) //time is a TimeInterval after which the audio will start
}
}
catch {
print(error)
}
}
I have spent a couple more days debugging this now. What is happening is the original play is being assigned to a specific AudioPlayer ID for example the print is: "Optional(<AVAudioPlayer: 0x600002802280>)"
When I call the function again to stop the play the AVAudioPlayer is assigned a different ID therefore it does not find that the old player is still playing and moves forward with playing a new sound on top of the old sound.
I am not sure how to store the AVAudioPlayer ID and then call the function so that it checks the store Player for if it is ".isPlaying"??
This happen because you initialize it before stopping current audio. Try this way:-
func superPlay(timeInterval: TimeInterval, soundName: String) {
// If audio is playing already then stop it.
if let audioPlayer = player {
if player.isplaying {
player.stop()
}
}
// Initilize audio player object with new sound
do {
alarmSound = soundName
//set up audio session
try AVAudioSession.sharedInstance().setCategory(.playAndRecord, options: [.defaultToSpeaker, .duckOthers])
try AVAudioSession.sharedInstance().setActive(true)
let url = Bundle.main.url(forResource: alarmSound, withExtension: "mp3")
player = try! AVAudioPlayer(contentsOf: url!)
player.numberOfLoops = -1
//Start AVAudioPlayer
print(timeInterval)
print(time)
let playbackDelay = timeInterval // must be ≥ 0
player.play(atTime: player.deviceCurrentTime + playbackDelay) //time is a TimeInterval after which the audio will start
}
catch {
print(error)
}
}
I am having some issues with playing sound in Xcode 9.2.
I tried watching few different tutorials and guides, but with no luck.
Either code is outdated, my app with crashes, the sound doesn't work, or it starts and cuts out after few milliseconds...
func updateDiceImages() {
// This is where the actual sound is attempted to play,
it should be triggered every time the button is pressed. Rest of the app works fine.
var soundEffect: AVAudioPlayer?
let path = Bundle.main.path(forResource: "rollingDice.wav", ofType:nil)!
let url = URL(fileURLWithPath: path)
do {
soundEffect = try AVAudioPlayer(contentsOf: url)
soundEffect?.play()
} catch {
print(error)
}
...
I am just not sure what I am doing wrong, tried tons of variations.
I am completely open to giving any information that I can provide. I didn't paste the whole code so it doesn't bother or swamp the people that try to read it.
Thank you so much for the help! =)
This is a taken piece of code from one of my applications, it works completely.
import AVFoundation
final class AudioManager {
private init() { }
static let shared = AudioManager()
private var player: AVAudioPlayer?
enum SoundType {
case incomingCall
}
open func playSound(_ type: SoundType) {
switch type {
case .incomingCall:
playIncomingCall()
}
}
// MARK: - Sounds
private func playIncomingCall() {
guard let url = Bundle.main.url(forResource: "incoming", withExtension: "wav") else { return }
playSound(url)
}
private func playSound(_ url: URL) {
do {
try AVAudioSession.sharedInstance().setCategory(AVAudioSessionCategoryAmbient)
try AVAudioSession.sharedInstance().setActive(true)
player = try AVAudioPlayer(contentsOf: url, fileTypeHint: AVFileType.wav.rawValue)
guard let player = player else { return }
player.numberOfLoops = -1 // infinity loop
player.prepareToPlay()
player.play()
debugPrint("playSound play sound")
} catch {
debugPrint(error.localizedDescription)
}
}
open func stop() {
player?.stop()
}
}
I have a struct with my audio player in it:
struct MT_Audio {
func playAudio(_ fileName:String, _ fileExtension:String, _ atVolume:Float) {
var audioPlayer = AVAudioPlayer()
if let audioPath = Bundle.main.path(forResource: fileName, ofType: fileExtension) {
let audioURL = URL(string:audioPath)
do {
audioPlayer = try AVAudioPlayer(contentsOf: audioURL!)
audioPlayer.volume = atVolume
audioPlayer.prepareToPlay()
audioPlayer.play()
} catch {
print(error)
}
}
}
}
//I'm calling it in viewDidLoad like this:
guard let fileURL = Bundle.main.url(forResource:"heartbeat-01a", withExtension: "mp3")
else {
print("can't find file")
return
}
let myAudioPlayer = MT_Audio() //<--RESOLVED THE ISSUE BY MAKING THIS A PROPERTY OF THE VIEWCONTROLLER
myAudioPlayer.playAudio("heartbeat-01a", "mp3", 1.0)
Since it doesn't crash and burn on the guard I know the file is there. I've also put a break point in after the try and I am getting to the audio player. When I go to the actual file and click on it in Xcode it plays. This fails on both the sim and device. Any help would be appreciated.
Looks like your audioPlayer is only stored within your playAudio function.
Try to keep the audioPlayer as an variable inside your class like this:
struct MT_Audio {
var audioPlayer: AVAudioPlayer?
mutating func playAudio(_ fileName:String, _ fileExtension:String, _ atVolume:Float) {
// is now member of your struct -> var audioPlayer = AVAudioPlayer()
if let audioPath = Bundle.main.path(forResource: fileName, ofType: fileExtension) {
let audioURL = URL(string:audioPath)
do {
let audioPlayer = try AVAudioPlayer(contentsOf: audioURL!)
audioPlayer.volume = atVolume
audioPlayer.prepareToPlay()
audioPlayer.play()
} catch {
print(error)
}
}
}
}
I have been trying to make a game to teach myself swift, and cant seem to get this code to work. I am extremely new to this, and can't seem to find out why it won't work... XCode doesn't flag any problems, build sucseed, and debugger even prints "Got to Stage 1 & Got to Stage 2... anything help?
I Imported AVFoundation..
class GAME {
class func SuperStartGame(playerwhowon1: SKSpriteNode) {
var player = AVAudioPlayer()
func PlaySound() {
guard let URL = Bundle.main.url(forResource: "PowerUp", withExtension: "mp3")
else {
print("Didn't Find URL")
return
}
do {
print("Got to Stage 1")
try AVAudioSession.sharedInstance().setCategory(AVAudioSessionCategoryPlayback)
try AVAudioSession.sharedInstance().setActive(true)
player = try AVAudioPlayer(contentsOf: URL, fileTypeHint: "mp3")
player.prepareToPlay()
player.play()
print("Got to Stage 2")
} catch let error as NSError {
print("error: \(error.localizedDescription)")
}
RoundNumber += 1
Round.text = "Round \(RoundNumber)"
if playerwhowon1 == Mine {
MyScore.run(addscoreM) {
PlaySound()
Round.run(NewRoundForRound) {
...
Code keeps going.. thats the only part that is relevant to the sound. I added the sound file to Xcode, and made sure it was added tot he project target... it is in my main bundle.
Make sure that your device isn't muted
mp3 file is copied to bundle
Example VC playing sound:
class ViewController: UIViewController {
var game = Game()
#IBAction func playAction(_ sender: UIButton) {
game.playSound()
}
}
class Game {
var player: AVAudioPlayer?
func playSound() {
guard let URL = Bundle.main.url(forResource: "SampleAudio", withExtension: "mp3") else {
print("Didn't Find URL")
return
}
do {
try AVAudioSession.sharedInstance().setCategory(AVAudioSessionCategoryPlayback)
try AVAudioSession.sharedInstance().setActive(true)
player = try AVAudioPlayer(contentsOf: URL, fileTypeHint: "mp3")
player?.prepareToPlay()
player?.play()
} catch let error as NSError {
print("\(error.localizedDescription)")
}
}
}
I have a code in Swift which plays a bird game. A bird collects eggs. I want to play a coin sound upon bird touching the egg. I tried code below but it's not playing upon contact. How can I accomplish it?
do {
// Preperation
try AVAudioSession.sharedInstance().setCategory(AVAudioSessionCategoryPlayback)
} catch _ {
}
do {
try AVAudioSession.sharedInstance().setActive(true)
} catch _ {
}
// Play the sound
do {
audioPlayer = try AVAudioPlayer(contentsOfURL: alertSound)
} catch _{
}
audioPlayer.prepareToPlay()
audioPlayer.play()
Create a path to the sound file
let path = NSBundle.mainBundle().pathForResource("(sound name)", ofType: (type) )!
Url for the path
var url = NSURL()
Variable to hold sound
var soundEffect: AVAudioPlayer!
Then when you want to play the sound
url = NSURL(fileURLWithPath: path)
do {
let sound = try AVAudioPlayer(contentsOfURL: url)
soundEffect = sound
sound.play()
} catch {
}
