        currentVol = Mathf.Pow(10, currentVol / 20);
        float targetValue = Mathf.Clamp(targetVolume, 0.0001f, 1);
        while (currentTime < duration)
        {
            currentTime += Time.deltaTime;
            float newVol = Mathf.Lerp(currentVol, targetValue, currentTime / duration);
            Master.SetFloat(Volume, Mathf.Log10(newVol) * 20);
