SuperpoweredPlayer - "the missing demo"

Real-time time stretching and pitch-shifting of audio files with Superpowered SDK in this simple demo for Android

This extends the PlayerExample with the following:

// onSpeedSlider - Handle TimeStretching events.
extern "C" JNIEXPORT void
Java_com_superpowered_playerexample_MainActivity_onSpeedSlider (
        JNIEnv * __unused env,
        jobject __unused obj,
        jint value
) {
    player->setTempo((value/10000.0), true);
}

// onPitchSlider - Handle PitchShifting events.
extern "C" JNIEXPORT void
Java_com_superpowered_playerexample_MainActivity_onPitchSlider (
        JNIEnv * __unused env,
        jobject __unused obj,
        jint value
) {
    player->setPitchShift(value);
}
