Detailed Description

FFT state management structure.

Manages FFT operations through the raw FFTDriver interface. This is a small, fixed-layout struct (just a driver pointer and a size), so it's allocated with plain new/delete rather than through the audio_tools Allocator used for the (much larger) EchoState buffers – consistent with how EchoState itself is created (see echoStateInitMc()).
