 		[AudioStreamGenerator] is a type of audio stream that does not play back sounds on its own; instead, it expects a script to generate audio data for it. See also [AudioStreamGeneratorPlayback].
 		Here's a sample on how to use it to generate a sine wave:
-		[codeblock]
+		[codeblocks]
+		[gdscript]
 		var playback # Will hold the AudioStreamGeneratorPlayback.
 		@onready var sample_hz = $AudioStreamPlayer.stream.mix_rate
 		var pulse_hz = 440.0 # The frequency of the sound wave.

+		        Player.Play();
+		        _playback = (AudioStreamGeneratorPlayback)Player.GetStreamPlayback();
+		        FillBuffer();
+		    }
+		}
+
+		public void FillBuffer()
+		{
+		    double phase = 0.0;
+		    float increment = _pulseHz / _sampleHz;
+		    int framesAvailable = _playback.GetFramesAvailable();
+
+		    for (int i = 0; i &lt; framesAvailable; i++)
+		    {
+		        _playback.PushFrame(Vector2.One * (float)Mathf.Sin(phase * Mathf.Tau));
+		        phase = Mathf.PosMod(phase + increment, 1.0);
+		    }
+		}

 		In the example above, the "AudioStreamPlayer" node must use an [AudioStreamGenerator] as its stream. The [code]fill_buffer[/code] function provides audio data for approximating a sine wave.
 		See also [AudioEffectSpectrumAnalyzer] for performing real-time audio spectrum analysis.
 		[b]Note:[/b] Due to performance constraints, this class is best used from C# or from a compiled language via GDExtension. If you still want to use this class from GDScript, consider using a lower [member mix_rate] such as 11,025 Hz or 22,050 Hz.
