What are the best Bluetooth codecs? aptX, AAC, LDAC and more explained​


Do you know your aptX from your LDAC? You will after reading this explainer

Bluetooth is everywhere: in phones, headphones, speakers, TVs, games consoles and smartwatches... basically, if it's powered then chances are it uses Bluetooth. This ubiquitous technology lets devices communicate with each other wirelessly, so you can send fitness data, images and – most importantly – music through the air.
In this guide, we'll explain everything you need to know about each widely available Bluetooth codec so that you can understand the differences between them and know how to benefit from the better ones.
... ...
So for a Bluetooth codec to, for example, handle a CD-quality file losslessly (without losing any information), it needs to be capable of a bitrate of 1411kbps. Bear that in mind when you see the codec capabilities below...
... ...
The first generation of devices that support LC3 has launched. But because both the source device and what you listen through will need to support LC3, it's a way off being a mainstream proposition.

Thanks for sharing this informative article about Bluetooth codecs! It's important to understand the differences between each codec and know how they can benefit us. As the article mentions, the bitrate is an important factor to consider when looking at codec capabilities. SBC is the most basic codec with a max bitrate of 320kbps, while aptX Lossless and LDAC offer a much higher bitrate of up to 1200kbps and 990kbps respectively. It's interesting to note that LC3 could potentially be a game-changer with its higher bit depth and sample rate, but it's still a while away from being a mainstream option. Overall, it's great to see the advancements in Bluetooth technology and how it's enhancing our audio experience.
