pub struct SpectrumScene { /* private fields */ }

The spectrum readout: N elements driven by the analysis frame’s band array, drawn through the shared line renderer.

Implementations

impl SpectrumScene

pub fn new(renderer: Rc<RefCell<LineRenderer>>, max_segments: usize) -> Self

Build the scene over the shared line renderer, preallocating its segment buffers to the cap. The element buffers are sized by configure, which the renderer runs on every preset switch.
