![]() It also didn’t help that SBC suffered from significant latency.Īt this point, the aptX codec had already been in use in a variety of settings, like filmmaking and broadcast, when the company that owned it realized it had the potential to work as an alternative to SBC. But audio that cuts out all the time? Forget about it. After all, you might be willing to put up with less-than-perfect sound. The trouble is that despite the fact that SBC is capable of delivering very good sound quality, many manufacturers hobbled its data rate in the early days of Bluetooth audio as a way of ensuring that dropouts wouldn’t happen. Having a default codec is great - it’s what ensures that all Bluetooth audio devices will work together. If you own a Bluetooth audio device, whether it’s a phone, a speaker, or a set of wireless headphones, it supports SBC. So codecs are employed to squeeze audio until it’s small enough to fit down that pipe.Įver since 2003, when the ability to stream stereo sound over Bluetooth was launched, sub-band coding (SBC) has been the default codec used to do that job. Because the wireless pipe that Bluetooth creates between devices is pretty narrow when compared to other tech like Wi-Fi, it can’t always accommodate digital music in its original format. Qualcomm builds on aptX Adaptive with aptX Losslessįirst, a quick primer on why we have Bluetooth codecs in the first place. ![]() What are Bluetooth codecs and do they really matter?

On the other hand, Sony's LDAC codec is used by a wide range of headphones, of which none rely on a Sony chipset. That said, headphone makers will still have to pay a royalty fee to Qualcomm, although there doesn't appear to be any headphones on the market that support aptX that aren't based on a Qualcomm or one of the older CSR chipsets from the time before Qualcomm acquired them. ![]() However, more advanced versions of aptX, such as aptX Adaptive and the rarely used low latency version of aptX are not included. Now it has come to light that just like Sony with its LDAC codec, Qualcomm has decided to add support for aptX to the Android Open Source Project (AOSP), which means all Android devices can support aptX as well as aptX HD without paying any royalty fees. Up until very recently, the phone makers had to pay a royalty fee to include support for the aptX codecs even if they used Qualcomm's chips in their phones and thus some companies-Samsung for example-decided not to include support for aptX. ![]() When it comes to smartphones, Qualcomm is by far the biggest chipset provider and as it happens, Qualcomm is also the owner of the various aptX audio codecs that many headphones support. ![]() One of the biggest issues with TWS and any other kind of wireless headphones for that matter, is limited support for various audio codecs, where many rely on the not so great SBC codec or AAC, simply because these are two codes that are supported by most of the devices that the headphones would be connected to. ![]()
