Struct AddConst 

pub struct AddConst<T: Sample + Add<Output = T>> { /* private fields */ }

AddConst adds a constant value to every sample.

Tags are preserved.

use rustradio::graph::{Graph, GraphRunner};
use rustradio::blocks::{ConstantSource, SignalSourceFloat, AddConst, NullSink};

let mut graph = Graph::new();

// Add a constant value. Could just as well use AddConst instead of Add.
let (src, src_out) = SignalSourceFloat::new(44100.0, 1000.0, 1.0);

// Sum up the streams.
let (sum, sum_out) = AddConst::new(src_out, 1.0);

graph.add(Box::new(src));
graph.add(Box::new(sum));

// Set up dummy sink.
let sink = NullSink::new(sum_out);
graph.run()?;
