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.
