Crossovers can have different frequencies, slopes, and alignments. Understanding how audio signals from […]
Unlocking the Secrets of Human Hearing: Understanding Weighting Curves in Audio
Though it might surprise you, human hearing is significantly more sensitive to some frequencies than others. You can think of this phenomenon as our built-in frequency response. However, unlike a speaker or amplifier, variations are not something we want to compensate for in an audio system—at least, not directly. Let’s discuss how human hearing works […]
CarPlay Sound Quality: Wired vs. Wireless—Which Is Better?
A reader requested that we compare the sound quality performance of wired and wireless Apple CarPlay. This is a great idea, as very little information is provided about the communication standards used to send audio signals wirelessly to a source unit. So, let’s look at distortion characteristics and frequency response to see if there is […]
Five Essential Car Audio Maintenance Tips
Unlike home audio systems, car stereo upgrades have to withstand harsh conditions. Your car, truck or SUV subjects your system to vibration, bumps and massive temperature changes. At home, as long as there isn’t a flood, everything should work fine for decades with regular dusting. Your car stereo system might not be quite as foolproof. […]
