Get an idea of how your mix will sound inside a car
To use the Car Test plug-in, it is as simple as pressing the “Power” button.
However, it is equally important that you adjust the output gain with the “Level” knob, so that your mix is not clipped. The Car Test plugin algorithm will gain specific frequencies, so it is likely to cut the mix if you do not reduce the input accordingly.
Ultimately, your studio monitoring setup and listening environment is what most influences the accuracy of this plugin.
The Car Test plug-in is simply designed to give you a similar frequency response, combined with simulated acoustics, to that of modern car speakers, so you can get a rough idea of what your mix might sound like inside them.
