Plays back audio generated using [AudioStreamGenerator]. This class is meant to be used with [AudioStreamGenerator] to play back the generated audio in real-time. https://godotengine.org/asset-library/asset/2759 https://godotengine.org/article/godot-32-will-get-new-audio-features Returns [code]true[/code] if a buffer of the size [param amount] can be pushed to the audio sample data buffer without overflowing it, [code]false[/code] otherwise. Clears the audio sample data buffer. Returns the number of frames that can be pushed to the audio sample data buffer without overflowing it. If the result is [code]0[/code], the buffer is full. Returns the number of times the playback skipped due to a buffer underrun in the audio sample data. This value is reset at the start of the playback. Pushes several audio data frames to the buffer. This is usually more efficient than [method push_frame] in C# and compiled languages via GDExtension, but [method push_buffer] may be [i]less[/i] efficient in GDScript. Pushes a single audio data frame to the buffer. This is usually less efficient than [method push_buffer] in C# and compiled languages via GDExtension, but [method push_frame] may be [i]more[/i] efficient in GDScript.
