Bluetooth Audio Codecs: Understanding the Tech
Bluetooth audio codecs dictate how audio data is encoded and transmitted wirelessly. Compatibility issues here can definitely cause connection problems or subpar audio quality. While iOS devices generally handle the most common codecs well, knowing a little about them might help you understand any limitations.
SBC (Subband Codec)
This is the standard Bluetooth audio codec and the lowest common denominator. All Bluetooth devices support SBC, but it offers the lowest audio quality compared to newer codecs. If your iPhone and car system only support SBC, audio quality might sound compressed or muddy.
AAC (Advanced Audio Coding)
AAC is Apple’s preferred audio codec and offers better audio quality than SBC. Most modern car infotainment systems support AAC, providing a clearer and more detailed listening experience. If your iPhone and car system both support AAC, this is likely what you’ll be using for audio streaming.
aptX and aptX HD
These are higher-resolution audio codecs developed by Qualcomm. They offer even better audio quality than AAC, approaching CD-quality sound. However, they are less commonly supported by car infotainment systems. Unless your car specifically lists aptX or aptX HD support, it’s unlikely to be in use.
LDAC
LDAC is a high-resolution audio codec developed by Sony. It transmits three times more data than standard Bluetooth, providing exceptional audio quality. Like aptX, LDAC is less common in car systems but is sometimes found in high-end models.
Understanding which codecs your iPhone and car support can help you troubleshoot audio quality issues. If you suspect a codec compatibility problem, there’s usually not much you can do directly (as codec selection is generally automatic). However, knowing this might help you manage expectations and understand limitations.
