AudioBufferSourceNode snippet:
var myAudioBuffSrcNode = audioContext.createBufferSource();
// Schedules for playback, but doesn't guarantee that
// playback will start right away.
myAudioBuffSrcNode.start();
How can one find out if a node is playing? So that something like this can be done:
if ( isPlaying ) {
myAudioBufferSrcNode.stop();
}

I use AudioPlayers package.
I have Button1 that plays the sounds. (Code Below)
AudioCache playerCache = new AudioCache(); // you already initialized this
AudioPlayer player = new AudioPlayer();
void _playFile(String yol, String name) async {
player = await playerCache.play(yol);
}
But there is another button which calling "Button2" has to stop all of the sounds at once. I wrote this :
void cancelPlay() {
print("stop");
playSounds.removeRange(0, playSounds.length);
player.stop();
player.stop();
}
However , when user click Button2 , it only stops the last sound. I want that to stop all of the sounds. How to do that ?
I guess The problem is, that every time i call _playFile() (press Button 1) a new instance of AudioPlayer is assigned to the player variable, hence in cancelPlay() the player variable holds only the last instance of AudiPlayer.
How can i do to store the instances in a list.
Thank you.
make a variable
List<AudioPlayer> audioPlayers = [];
every time you tap button1, add new audioPlayer
audioPlayers.add(new AudioPlayer());
then when you tap on button2, do something like this to stop every audioPlayer
audioPlayers.forEach((audioPlayer) => audioPlayer.stop());
or even better would be function to toggle the AudioPlaybackState of audioPlayers, so if they are paused then play and vice versa. Ofcourse this example is based on presumption that every audioPlayer controller has same AudioPlaybackState as first:
void toggleAudioPlayers() {
if (audioPlayers.first.playbackState == AudioPlaybackState.playing) {
audioPlayers.forEach((audioPlayer) => audioPlayer.stop());
} else {
audioPlayers.forEach((audioPlayer) => audioPlayer.play());
}
}
Dont forget to dispose every audioPlayer controller to prevent memory leaks:
audioPlayers.forEach((audioPlayer) => audioPlayer.dispose());
AudioPlayer.players.forEach((key, value) {
value.stop();
});
when you play another audio you need to call this code before
I'm coding a small game with the Flutter Framework.
I'm using audioplayers for the Sounds.
It works fine like this, when calling it for example 2 times a second.
But whenn I call it more than 5 times and again in the next second at some point the sound has like a delay and then after a second or so all the sounds play at once :) That sounds weired.
I also tested the audioplayers example from github on my iphone. Repeating the sounds in low frequency is ok, but when I repeat clicking the button as fast as possible at some point it gets some delay and the same thing is happening.
Is there some way to stop the previous Sound before and then playing the next one or isnt this possible?
Or is there some other Idea how to deal with the sounds?
This is how I use it:
AudioCache upgradeSound = new AudioCache();
void playUpgradeSound() {
_playUpgradeSound(upgradeSound);
}
void _playUpgradeSound(AudioCache ac) async{
await ac.play('audio/upgr.mp3');
}
Thank you very much in advance
I solve similar problem by having singleton class, and after first play I can get the state, and I can stop previous play.
class Audio {
static final playerCache = AudioCache();
static AudioPlayer audioPlayer;
static void play(String audioName) async {
audioPlayer = await playerCache.play('$audioName.mp3');
}
static void stop() {
audioPlayer.stop();
}
}
...
child: IconButton(
onPressed: () {
try {
if (Audio.audioPlayer.state ==
AudioPlayerState.PLAYING) {
Audio.stop();
} else {
Audio.play('bid');
}
} catch (e) {
Audio.play('bid');
}
},
...
There is a line of code in its own documentation.
To use the low latency API, better for gaming sounds, use:
AudioPlayer audioPlayer = AudioPlayer(mode: PlayerMode.LOW_LATENCY);
In this mode the backend won't fire any duration or position updates. Also, it is not possible to use the seek method to set the audio a specific position. This mode is also not available on web.
I hope it is useful.
in my game, when the player dies, a dying sound is played and once the sound is over, the scene is supposed to be reloaded when the user still has enough lives.
Before I had the sound, the play died instantly upon calling the death() function:
public static void Death()
{
AddCoinScript.coinCounter = 0;
LivesScript.livesCounter--;
if (LivesScript.livesCounter > -1)//to get 0 live
{
Debug.Log("TIMER");
var currentScene = SceneManager.GetActiveScene();
SceneManager.LoadScene(currentScene.name);
}
else
{
//TO DO GameOver
}
}
This worked like a charm.
But now I added a death sound to it. Unfortunately, unity doesnt provide an event handler for when the sound is done playing (I want the scene to be reloaded not instantly anymore, but after the death sound is done playing), so I have decided to take it upon myself to just build a timer. The timer fires right after the death sound is over. This is what this function has become:
public static void Death()
{
AddCoinScript.coinCounter = 0;
LivesScript.livesCounter--;
PlayDeathSound();
System.Timers.Timer timer = new System.Timers.Timer();
timer.Interval = aSDeath.clip.length * 1000;
timer.Start();
timer.Elapsed += delegate
{
timer.Stop();
if (LivesScript.livesCounter > -1)//to get 0 live
{
Debug.Log("TIMER");
var currentScene = SceneManager.GetActiveScene();
SceneManager.LoadScene(currentScene.name);
}
else
{
//TO DO GameOver
}
};
}
As you can see, to make sure the timer REALLY fires, I set up a "debug.Log("TIMER")" to see, if it really works. And guess what: it does. The debug now shows "TIMER" in its console. But you know what doesnt work anymore? The two lines of code right beneath that.
var currentScene = SceneManager.GetActiveScene();
SceneManager.LoadScene(currentScene.name);
It's the same exact lines that worked just before - but when fired from the timer, they just get ignored? How is this even possible?
When I change it all back, it works again. Only when the timer fires the two lines, they get ignored.
This is totally odd or am I missing something? Thank you!
Okay I am not an expert on C# and delegate but apparently it creates a separate thread and you can only use SceneManager.GetActiveScene on main thread.
Since i am not so sure about delegate i will offer an easier solution. You can use a coroutine since you know how much you have to wait like this:
public void Death()
{
StartCoroutine(DeathCoroutine());
}
IEnumerator DeathCoroutine()
{
AddCoinScript.coinCounter = 0;
LivesScript.livesCounter--;
PlayDeathSound();
// wait for duration of the clip than continue executing rest of the code
yield return new WaitForSeconds(aSDeath.clip.length);
if (LivesScript.livesCounter > -1)//to get 0 live
{
Debug.Log("TIMER");
var currentScene = SceneManager.GetActiveScene();
SceneManager.LoadScene(currentScene.name);
}
else
{
//TO DO GameOver
}
}
What about using a coroutine ? You just start it when the player dies, and yield while your sound is still playing.
My Codename One app features audio playback in the background when the user taps the screen. The audio I use is an mp3. Here is how I use the Media playback :
public static void playSound(boolean stop) {
sound.reset(); // The input stream needs to go back to the beginning
Media myClip = MediaManager.createMedia(sound, "audio/mp3", () -> {
// If there is no order to stop playback, we keep playing when it has completed (looping)
playSound(false);
});
if (!stop) {
myClip.play();
} else {
myClip.cleanup();
}
}
So hen the user taps the screen components change and I pass true to playSound method. On Android the current playback stops not on iOS with an iPhone 4.
Please note that when the app gets minimized (center button pressed) the playback stops (even if I don't call cleanup() on the Media which I do on Android to stop the playback when the app is minimized).
How can I stop the playback on iPhone ?
Any help appreciated,
#Shai pointed me to the right direction so here is the code finally used :
Media myClip = null;
public static void playSound(boolean stop) {
sound.reset(); // The input stream needs to go back to the beginning
/**
* If the media is playing we don't create it
* otherwise we would have several media in the wild
* that could not be stopped
*/
if (myClip == null || !myClip.isPlaying()) {
myClip = MediaManager.createMedia(sound, "audio/mp3", () -> {
// If there is no order to stop playback, we keep playing when it has completed (looping)
playSound(false);
});
}
if (!stop) {
myClip.play();
} else {
myClip.cleanup();
}
}
I'm trying to dynamically load and play a video file. No matter what I do, I cannot seem to figure out why the audio does not play.
var www = new WWW("http://unity3d.com/files/docs/sample.ogg");
var movieTexture = www.movie;
var movieAudio = www.movie.audioClip;
while (!movieTexture.isReadyToPlay) yield return 0;
// Assign movie texture and audio
var videoAnimation = videoAnimationPrefab.GetComponent<VideoAnimation>();
var videoRenderer = videoAnimation.GetVideoRenderer();
var audioSource = videoAnimation.GetAudioSource();
videoRenderer.material.mainTexture = movieTexture;
audioSource.clip = movieAudio;
// Play the movie and sound
movieTexture.Play();
audioSource.Play();
// Double check audio is playing...
Debug.Log("Audio playing: " + audioSource.isPlaying);
Every time I receive Audio playing: False
I've also tried using a GUITexture using this as a guide, but no dice. There are no errors displayed in the console.
What am I doing wrong that makes the audio never work?
Thanks in advance for any help!
Changed to:
while (!movieTexture.isReadyToPlay) yield return 0;
var movieAudio = movieTexture.audioClip;
Even though AudioClip inherits from Object, a call to movieTexture.audioClip seems to return a copied version instead of returning a reference by value to the object. So at the time I was assigning it, it had not been created yet and had to wait until the movie was "Ready to Play" until fetching the audioClip.
