When mixing multiple sounds together, you should not create multiple devices. Instead you should create only a single
device and then mix your sounds together which you can do by simply summing their samples together. The simplest way to
do this is to use floating point samples and use miniaudio&#39;s built-in clipper to handling clipping for you. (Clipping
is when sample are clampled to their minimum and maximum range, which for floating point is -1..1.)
