<description>
AudioEffectCapture is an AudioEffect which copies all audio frames from the attached audio effect bus into its internal ring buffer.
Application code should consume these audio frames from this ring buffer using [method get_buffer] and process it as needed, for example to capture data from a microphone, implement application defined effects, or to transmit audio over the network. When capturing audio data from a microphone, the format of the samples will be stereo 32-bit floating point PCM.

When used directly in an [AudioStreamPlayer] node, [AudioStreamMicrophone] plays back microphone input in real-time. This can be used in conjunction with [AudioEffectCapture] to process the data or save it.

<member name="audio/enable_audio_input" type="bool" setter="" getter="" default="false">
If [code]true[/code], microphone input will be allowed. This requires appropriate permissions to be set when exporting to Android or iOS.
[b]Note:[/b] If the operating system blocks access to audio input devices (due to the user's privacy settings), audio capture will only return silence. On Windows 10 and later, make sure that apps are allowed to access the microphone in the OS' privacy settings.

The mixing rate used for audio (in Hz). In general, it's better to not touch this and leave it to the host operating system.
