So it is going to be something like this:

int main(int argc, char *argv[])
{
    NewSound *mynewsound[2];
    vector<NewSound*> newusblist;

    mynewsound[0] = new SoundIC7410{argv[1]};	/* IC-7410 */
    mynewsound[1] = new SoundSoft66{argv[2]};	/* Soft66LC4 */
    for(int i=0;i<2;i++) {
        newusblist.push_back(mynewsound[i]);    /* better ways to do this? */
    }
    // ...
}

class NewSound : public Gtk::Box {
public:
    virtual void draw_waveform (Gtk::Box&) = 0; // a pure virtual function
    virtual void draw_waterfall(Gtk::Box&) = 0; // a pure virtual function
    virtual ~NewSound();
};

struct AlsaParams { // Advanced Linux Sound Architecture
    // ...
};

class SoundIC7410 : public NewSound, protected AlsaParams {
public:
    SoundIC7410();
    SoundIC7410(char *s);
    virtual ~SoundIC7410();
    void draw_waveform (Gtk::Box&) override;
    void draw_waterfall(Gtk::Box&) override;
    // ...
private:
    char* sound_device = nullptr;
    // ...
};

class SoundSoft66 : public NewSound, protected AlsaParams {
    // ...
};

void f(vector<NewSound*> newusblist&) {
    // Gtk::Box mybox;
    for(auto x : newusblist) {
        x->draw_waveform (mybox);
        x->draw_waterfall(mybox);
    }
}

void SoundIC7410::draw_waveform(Gtk::Box& box) const{
    // Gtk::DrawingArea ttt;
    // ttt.set_size_request(200,200);
    box.pack_start(ttt, FALSE, FALSE, 0);
}
