Struct Add 

pub struct Add<Ta, Tb, Tout>
where
    Ta: Sample + Add<Tb, Output = Tout>,
    Tb: Sample,
    Tout: Sample,
{ /* private fields */ }

Adds two streams, sample wise.

Output tags are taken from the first stream. Tags from the other input stream is discarded.

To add a constant value to a stream, instead use AddConst.

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

let mut graph = Graph::new();

// Add a constant value. Could just as well use AddConst instead of Add.
let (src1, src1_out) = ConstantSource::new(1.0);
let (src2, src2_out) = SignalSourceFloat::new(44100.0, 1000.0, 1.0);

// Sum up the streams.
let (sum, sum_out) = Add::new(src1_out, src2_out);

graph.add(Box::new(src1));
graph.add(Box::new(src2));
graph.add(Box::new(sum));

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