//Initialize FMOD FMOD::System* system; FMOD::System_Create(&system); system->init(32, FMOD_INIT_NORMAL, NULL); //Load a sound FMOD::Sound* sound; system->createSound("sound.mp3", FMOD_DEFAULT, NULL, &sound); //Play the sound and adjust its volume FMOD::Channel* channel; system->playSound(sound, NULL, false, &channel); channel->setVolume(0.5f);In this example, we first initialize the FMOD system and load a sound file. We then play the sound using the `system->playSound()` function which returns a `Channel` object that represents the playing instance of the sound. Finally, we adjust the volume of the sound using the `channel->setVolume()` function. The code above uses the FMOD package library, which is part of the FMOD Studio toolset. FMOD Studio is a complete audio authoring and management tool that allows developers to create and manage audio content for their games or applications.
