Happy new year to the wonderful Godot community!
We're starting a new decade with a well-established, non-profit, free
and open source game engine, and tons of further improvements in the
pipeline from hundreds of contributors.
Godot will keep getting better, and we're looking forward to all the
games that the community will keep developing and releasing with it.
Prior to this fix, AudioEffectRecordInstance::init() was called before recording_active is set to true in AudioEffectRecord::set_recording_active(). This was setting is_recording to false in AudioEffectRecordInstance, because is_recording updates to the value of recording_active in AudioEffectRecordInstance::_io_thread_process(). To fix this issue, AudioEffectRecordInstance::init() is now called after recording_active is set to true.
Made AudioFrame and Vector2 equivalent for casting.
Added ability to obtain the playback object from stream players.
Added ability to obtain effect instance from audio server.
