如果可以將大小為 ``amount`` 的緩衝區推送到音訊取樣資料緩衝區而不會使其溢出，則返回 ``true``\ ，否則返回 ``false``\ 。

:ref:`int<class_int>` **get_frames_available**\ (\ ) |const| :ref:`🔗<class_AudioStreamGeneratorPlayback_method_get_frames_available>`
|
|
|
|
返回能夠推送到音訊取樣資料緩衝區而不使其溢出的影格數。如果結果為 ``0``\ ，則緩衝區已滿。

將多個音訊資料影格推送到緩衝區。這通常比 C# 中的以及通過 GDExtension 編譯的語言中的 :ref:`push_frame()<class_AudioStreamGeneratorPlayback_method_push_frame>` 效率更高，但在 GDScript 中的 :ref:`push_buffer()<class_AudioStreamGeneratorPlayback_method_push_buffer>` 的效率可能\ *更低*\ 。
