// Set the mute state of the master volume.
// Mute
NodeAudioVolumeMixer.muteMaster(true);
// UnMute
NodeAudioVolumeMixer.muteMaster(false);


// Get the master volume.
NodeAudioVolumeMixer.getMasterVolumeLevelScalar();

// Set the master volume to 50%.
NodeAudioVolumeMixer.setMasterVolumeLevelScalar(0.5);


// Get a audio session.
const sessions = NodeAudioVolumeMixer.getAudioSessionProcesses();

// Find Google Chrome by session.
const session = sessions.find((value) => {
    return value.name === "chrome.exe";

console.log(`Google Chrome: ${NodeAudioVolumeMixer.isAudioSessionMuted(session.pid)}`);

// Set the mute state of Google Chrome
// Mute
NodeAudioVolumeMixer.setAudioSessionMute(session.pid, true);
// UnMute
NodeAudioVolumeMixer.setAudioSessionMute(session.pid, false);

// Get the volume of Google Chrome.
