I am working on a project, and I want to play some music notes out from an SD card to an I2S amplifier(MAX98357A) using ESP32. But I did not find anything useful. Just what I want to do is I have twelve(12) buttons and I want each button press to play a music like if I press button one then one music play and when it finishes the other one doesn't play by itself. Yes, and when I play one and then play another, the first one stops and the second one starts playing. Do I have to use pin interrupts for this?
Can someone tell me about the proper libraries for it?

What I mean is, instead of playing an audio clip in the audio source in Unity3D, can I play whatever music is playing from another software and place that in the world with 3D sound.
I am using music to guide the player somewhere, but rather than having one song that I hardcode in, I would like to use the music or sound the player already listens to before starting the game. I must be able to change the volume and balance as the sound is suposed to come form somewhere in the 3D world
I have an app that shows list of movies in a table view. When I play them one after another on device it works just great. But when I switch to Apple TV over AirPlay it doesn't work anymore. It play's the first video on ATV ok but after a switch to the next video the screen on ATV start blinking/flickering and after a few seconds it falls back playing on a device. I am using MPMoviePlayerController for playing stream videos.
I also found out that if previous video finished playing over AirPlay it tries to start the next one over AirPlay also. Is this intended behaviour?
Is this kind a related with property allowsAirPlay?
I think I've found a solution. Before you switch playing another video you should stop the previous one:
[self.moviePlayer stop];
This is not needed if you are not playing via AirPlay cos the next video will automatically stop previous one by nature - you can not play two videos at once.
But If you do play video over AirPlay you need to stop previous one first and than play the next one.
This solution works for me.
I do not want any code but want to get a reference about my question mentioned below...
There is background music available and there is recording option in my app...
Once I start recording , application records my sound and when play button clicks , It will play the recording along with the background music...
I had use this Link but can not get as I want...
I think there is a mechanism like merging two audio files and make it one before playing....
How can I achieve this by coding... Is there any reference link or any sample code available?
Thnx in advance...
Most people mistake the one instance of AVAudioPlayer as the unit that plays the sound directly, but it doesnt. Mixing is done by the OS, not by the instance of AVAudioPlayer.
With other words:
No one says you can't have more then one AVAudioPlayer.
Create one for you background and let it play. Create another instance of AVAudioPlayer for you recorded sound and let it play. Voila
I can have a UIWebView with the .m3u file opened, which will go to the webview with a play button displayed, and that automatically goes to the quicktime player and starts playing the stream. But when I press the done button, it goes back to the UIWebView with a little play button in the middle, and from there you can go back to the previous screen (it was selected from a tableview). So I just want it to automatically load the quicktime player in the view. How can I do that?
An m3u file is nothing more than a text file listing MP3 (and / or other format) digital audio files to be interpreted by player software as a series of audio files to be played in succession. So my best guess (I am about to implement this myself, so I'll find out soon if it actually works that way) at going about this is:
read in m3u file
parse for stream URLs and store these
choose / let user decide which one to play
Implement streaming player like explained here.
There is no step 5. I hope.
What is the right way to play next file using Audio Queue Services? When "play next" button is pressed should I first call AudioQueueStop and then AudioQueuePrime/AudioQueueStart or it is enough to just fill buffers with next file data?
The problem is that the latter gives me sound glitches on iPhone.
Did you find a good solution?
You may have to reset the audio queue also, as the encoding might be different for each file.
