AudioStreamCallbackImpl

class AudioStreamCallbackImpl(onAudioReadyBlock: (buffer: FloatArray, numFrames: Int) -> Int) : AudioStreamCallback

Concrete implementation of AudioStreamCallback that delegates to a lambda.

This class exists to provide a Swift-friendly way to create callback instances, since Swift cannot directly create anonymous implementations of Kotlin interfaces.

Usage from Swift:

let callback = AudioStreamCallbackImpl { buffer, numFrames in
    // Fill buffer with audio data
    return numFrames
}
