For the time being we don't support writing a description for those, preferring
having all details in the method's description.
Using self-closing tags saves half the lines, and prevents contributors from
thinking that they should write the argument or return documentation there.

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.
