So I am following through an old tutorial and I think with the changes in xcode and swift this code is now no longer usable, but i am not sure. Would love some help.
Declaring constant for the audio effect
let cannonSound = SKAction.playSoundFileNamed("cannon.wav", waitForCompletion: false)
Calling the audio effect within my funtion
let hotdogSequence = SKAction.sequence([cannonSound, moveHotdog, deleteHotdog])
hotdog.run(hotdogSequence)
For more info I am using SpriteKit in Xcode and this code is contained within GameScene.swift file.
Update:
The error I receive is
2017-03-30 00:52:43.631 Ballpark Weiner[95999:1983181] SKAction: Error loading sound resource: "cannon.wav"
The game doesn't crash just no sound plays
This message usually means that the file cannot be found in your project or might be corrupt.
You should check that the file is actually copied into your project and is spelled correctly. Its case sensitive so if the actual file is called "Cannon.wav" it will not work.
Hope this helps

Trying to use AudioKit 5 to dynamically create a player with a mixer, and attach it to a main mixer. I'd like the resulting chain to look like:
AudioPlayer -> Mixer(for player) -> Mixer(for output) -> AudioEngine.output
My example repo is here: https://github.com/hoopes/AK5Test1
You can see in the main file here (https://github.com/hoopes/AK5Test1/blob/main/AK5Test1/AK5Test1App.swift) that there are three functions.
The first works, where an mp3 is played on a Mixer that is created when the controller class is created.
The second works, where a newly created AudioPlayer is hooked directly to the outputMixer.
However, the third, where I try to set up the chain above, does not, and crashes with the "player started when in a disconnected state" error. I've copied the function here:
/** Try to add a mixer with a player to the main mixer */
func doesNotWork() {
let p2 = AudioPlayer()
let localMixer = Mixer()
localMixer.addInput(p2)
outputMixer.addInput(localMixer)
playMp3(p: p2)
}
Where playMp3 just plays an example mp3 on the AudioPlayer.
I'm not sure how I'm misusing the Mixer. In my actual application, I have a longer chain of mixers/boosters/etc, and getting the same error, which led me to create the simple test app.
If anyone can offer advice, I'd love to hear it. Thanks so much!
In your case, you can swap outputMixer.addInput(localMixer) and localMixer.addInput(p2) then it works
Once you have started the engine: work backwards from the output with your audio chain connections. So, your problem was that you attached a player to a mixer that was disconnected from the output. You needed to first attach the output to the mixer and then attach that mixer to the player.
The advice I wound up getting from an AudioKit contributor was to do everything possible to create all audio objects that you need up front, and dynamically change their volume to "connect" and "disconnect", so to speak.
Imagine you have a piano app (a contrived example, but hopefully gets the point across) - instead of creating a player when a key is pressed, connecting it, and disconnecting/disposing when the note is complete, create a player for every key on startup, and deal with them dynamically - this prevents any weirdness with "disconnected state", etc.
This has been working pretty flawlessly for me since.
Very simple issue but I have no idea if anyone can help me with it. Perhaps it is a bug? I simply want to load this order but get the warning that WARNING: C:\Users\Usuario\Documents\Corona Projects\BalloonTap\game.lua:259: audio.loadSound() failed to create sound 'audio/pop.wav´.
The directory of the audio of the audio file is C:\Users\Usuario\Documents\Corona Projects\BalloonTap\audio
The code is:
balloonPop = audio.loadSound( "audio/pop.wav")
Any possible fixes? I have tried different audio files and renaming file. I have tried putting it in the main folder and just saying balloonPop = audio.loadSound( "pop.wav") but that fails as well.
When sounds are not loading in Corona, it is a good idea to check that the file can be found:
local filename = "audio/pop.wav"
if system.pathForFile( filename , system.ResourceDirectory ) == nil then
print("WARNING: cannot find audio file "..filename )
end
The fact that the sound could not be created suggests, however, that this is not the problem. From the Audio Usage/Functions Guide:
Cross-platform .wav files must be 16-bit uncompressed.
Is your sound file in the correct format?
Im new to swift but i like it more than obj-c as it looks a bit like java does to me from syntax wise compared to obj-c.
My problem is now that most of the source code samples are for obj-c so theyre unreadable for me =)
Anyway i managed to run a few code snippets like this(im not at my mac but they were similar):
let steamingURL:NSURL = NSURL(string: "http://....")!
let player = AVPlayer(URL: steamingURL)
player.allowsExternalPlayback = false
PlayWorkoutViewController.playerController = AVPlayerViewController()
PlayWorkoutViewController.playerController.player = player
self.addChildViewController(PlayWorkoutViewController.playerController)
self.view.addSubview(PlayWorkoutViewController.playerController.view)
PlayWorkoutViewController.playerController.view.frame = videoContainerView.frame
PlayWorkoutViewController.playerController.showsPlaybackControls = false
player.play()
resulting in a Play Button with a line trough it, it doesnt play the Stream.
The stream source is a mpg1/2 stream according to VLCPlayer and its coming from a Linux based satellite receiver.
Another thing i tried was to change that "string:" part to "fileURLWithPath:" at the NSURL variable but that didnt work either.
Is there a way to Buffer the stream or is this just a codec issue, what workaround options do i have?
Im hesitating since three days, i hope its not a duplicate question, thanks.
EDIT: content of the stream.m3u file:
EXTM3U
EXTVLCOPT--http-reconnect=true 192.168.178.20:8001/1:0:1:445D:453:1:C00000:0:0:0:
Security setting might be the problem. Go to info.plist and Add "App Transport Security Settings". Under that add "Allow Arbitrary Loads" and set it to YES. I hope this fixes the problem.
I want to play the keyboard 'click' sound when pressing buttons in my app.
How do I access this sound clip with Monotouch? I don't want to pass my own sound using AudioToolbox SystemSound.FromFile(). So far all my searches have led to this solution or Objective-C code using 'AudioServicesCreateSystemSoundID' which I'm having trouble translating to C#.
With iOS 7.0 and higher, Stephane Delcroix answer seems not to work anymore...
But you can easily find the path to all the sounds in this nice project:
https://github.com/TUNER88/iOSSystemSoundsLibrary
Here is the code I used und iOS 7 (take care, it might not work with the simulator!)
private const string NotificationSoundPath = #"/System/Library/Audio/UISounds/New/Fanfare.caf";
public static void TriggerSoundAndViber()
{
SystemSound notificationSound = SystemSound.FromFile(NotificationSoundPath);
notificationSound.AddSystemSoundCompletion(SystemSound.Vibrate.PlaySystemSound);
notificationSound.PlaySystemSound();
}
Also the using() construct in the answer above caused trouble in my case... it seems like it released the sound too early, I only can hear it (and even then not complete with viber) with a breakpoint on PlaySystemSound().
Well, that's not a 1:1 port from the code in Playing system sound without importing your own, but this should do the work:
var path = NSBundle.FromIdentifier ("com.Apple.UIKit").PathForResource ("Tock", "aiff");
using (var systemSound = new SystemSound (NSUrl.FromFilename (path))) {
systemSound.PlaySystemSound ();
}
SystemSound is defined in MonoTouch.AudioToolbox. Make sure to also look at MonoTouch Play System Sound and MonoTouch: Playing sound
i have tried to record the audio in wav format and i succeeded but when i try to play that file, it gives an error that 'media file is of unsupported format'.
the main portion of code is as follows:
player = Manager.createPlayer("capture://audio?encoding=pcm&rate=44100&bits=16&channels=1");
player.realize();
controller = (RecordControl) player.getControl("RecordControl");
controller.setRecordLocation("file:///SDCard/BlackBerry/voicenotes/voice.wav");
//controller.setRecordSizeLimit(396900);
controller.startRecord();
player.start();
Thread.sleep(7000);
controller.commit();
player.close();
This code works well and it gave me a voice.wav file but i am not able to play this file.Is there is something which i forget?
Thanks in advance.
Sounds like the same problem as here:

Essentially, you need to add the RIFF/WAVE-header for the recorded data yourself, see the last post on the thread for example.
