AudioStreamBufferData

Container for streaming audio data buffers provided during AudioStreamDataCallback execution.

This class supplies a buffer indicating where to write audio stream data when the callback is invoked. The frameCount and frameSize properties specify how much data can be written into the buffer.

Ownership & Lifecycle

• Owner: The audio engine — it allocates and destroys instances.

• Allocation: Managed internally by the audio engine.

• Lifetime: Valid only during the callback execution.

Usage Example

object pullCallback : AudioStreamDataCallback {
    override fun onMoreData(buffer: AudioStreamBufferData) {
        val byteArray = ByteArray(bufferSize.toInt())
        val readSize = audioStream.read(byteArray)
        buffer.put(byteArray)
        if (readSize < bufferSize) {
            val remainingBytes = bufferSize - readSize
            buffer.put(ByteArray(remainingBytes.toInt()) { 0 })
        }
        buffer.flip()
    }
}

Thread Safety

• Access only within the callback thread context.

• Not thread-safe for concurrent usage.
