Sorry, but it uses .AU files ( download and use Jode, then you got:

...
    public void init(AppletStarter appletstarter) {
        applet = appletstarter;
        URL url = appletstarter.getCodeBase();
        int i = 1;
        STone2 = new AudioClip[12];
        for (int i_0_ = 0; i_0_ < 12; i_0_++) {
            appletstarter.setLabel("Loading audio clip " + i + " of 36 ...");
            i++;
            String string = "st-c2/st" + (i_0_ + 1) + ".au";
            STone2[i_0_] = appletstarter.getAudioClip(url, string);
            if (STone2[i_0_] == null)
                System.out.println("Couldn't load audio clip " + url + string);
        }
        STone3 = new AudioClip[12];
        for (int i_1_ = 0; i_1_ < 12; i_1_++) {
            appletstarter.setLabel("Loading audio clip " + i + " of 36 ...");
            i++;
            String string = "st-c3/st" + (i_1_ + 1) + ".au";
            STone3[i_1_] = appletstarter.getAudioClip(url, string);
            if (STone3[i_1_] == null)
                System.out
                    .println("Couldn't create audio clip " + url + string);
        }
        STone6 = new AudioClip[12];
        for (int i_2_ = 0; i_2_ < 12; i_2_++) {
            appletstarter.setLabel("Loading audio clip " + i + " of 36 ...");
            i++;
            String string = "st-c6/st" + (i_2_ + 1) + ".au";
            STone6[i_2_] = appletstarter.getAudioClip(url, string);
            if (STone6[i_2_] == null)
                System.out
                    .println("Couldn't create audio clip " + url + string);
        }
        appletstarter.appletLoaded();
    }
...
)
