Control in your car for mixing… What?
In addition to burning a few CD-Rs to listen to how your mix sounds in an average car stereo environment, there is actually a deeper (no pun intended) advantage to doing this. Acoustic reflections cause a series of peaks and dips throughout the low range of frequencies. Most car stereos suffer from what can be called acoustic comb filtering because much of the low-frequency energy passes right through the car’s lightweight shell to the outside. As it passes through the shell of the car, the low-end response is more uniform compared to many home studio control environments, therefore it is not reflected.
That is why at the next red light you’ll find yourself hearing the boom boom boom on the 1,2,3, and 4 beats coming from the car next to you. Maybe give a high five to their excellent acoustic comb filtering. 🙂
