Description

Hello everyone,
I was trying to play buffer with mono-channel format audio, but somehow the program is crashing.
Like this,

player = AudioPlayer();
let buffer = arrayBuffer[self.currentBufferIndex]; // holds array of buffer.
try? player.load(buffer: arrayBuffer[self.currentBufferIndex]);
engine.output = player
player.play();
player.completionHandler = playBuffer

Just to be specific the format is like this,

ASBD: {
    mSampleRate: 16000.000000 
    mFormatID: 'lpcm' 
    mFormatFlags: 0xc 
    mBytesPerPacket: 2 
    mFramesPerPacket: 1 
    mBytesPerFrame: 2 
    mChannelsPerFrame: 1 
    mBitsPerChannel: 16 	
} 

It's mandatory for me to play mono-channel audio. Unfortunately, I can't make it.
What do you think can be done?

Before try? player.load(buffer: arrayBuffer[self.currentBufferIndex]); try setting the player.file to your audio file. That should update the format of the player.

Also try loading the audio file and buffer AFTER setting the engine's output.
