We don't use that info for anything, and it generates unnecessary diffs every time we bump the minor version (and CI failures if we forget to sync some files from opt-in modules (mono, text_server_fb).

|
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 an [AudioStreamMicrophone], 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.

[b]Note:[/b] [member ProjectSettings.audio/driver/enable_input] must be [code]true[/code] for audio input to work. See also that setting's description for caveats related to permissions and operating system privacy settings.
