Mixer Stage

[MarkAHarley]

As a daft engineer, I want to create a mixer to combine multiple signals so that all the filter outputs can be combined.

Sucess Criteria:

• UML Class diagram
• Logic for combining signals

This shouldn't need any scaling logic as the audio is already seperated into frequency bands which just need to be recombined by summing.

This is the class interface I'll be using

template <std::size_t num_banks> class Mixer {
private:
    std::array<Pipe<Audio>, num_banks> input_pipes;
    Pipe<Audio> output_pipe;

public:
    Mixer (std::array<Pipe<Audio>, num_banks> input_pipes, Pipe<Audio> output_pipe);
    void run();
};
