I have audioMixerGroup.audioMixer.GetFloat("AllVolume", out tmp);
tmp will have volume in db. I vant to convert db (-80, 0) to slider's value (0, 1).
in short, I need to do How to set a Mixer's volume to a slider's volume in Unity? just the other way around
You can create a Remap function:
float Remap(float value, float min1, float max1, float min2, float max2)
{
return min2 + (value - min1) * (max2 - min2) / (max1 - min1);
}
Implementation:
audioMixerGroup.audioMixer.GetFloat("AllVolume", out tmp);
slider.value = Remap(tmp, -80f, 0f, 0f, 1f);
