Just a simple bot that increases the volume of voice messages. Maybe your vis-a-vis forgot to disconnect airpods and left them in his pocket while talking to you. Or maybe you just want to make your voice louder. This bot is for you. Use /setvolume command to set volume multiplier i.e. how much louder the voice message should be. And then just simply send or forward a voice message to this chat, and I'll return a louder version!
