Relationship between AptX and dynamic drivers to deliver vibrant audio performance

By Cleer Audio Let's face it: Bluetooth audio quality isn't yet good enough to satisfy a wide audience, and many competing "advanced" codecs have emerged to fill the void left by the sub-codec.

Qualcomm's aptX is often recommended in headphones and smartphones because it "brings audio quality similar to CD" while aptX HD is "indistinguishable from Hi-Res Audio". Strong claims for Bluetooth technology, but is it true?

Compressing audio into a package small enough to send over a data-limited connection is a commercial impossibility. Codecs constantly adjust the audio quality to save bandwidth, which often means distortion, noise, compression, and poor quality often arise as a result. So how does aptX achieve its audio quality and what is its relationship with dynamic audio drivers?

Let's start by looking at dynamic drivers

The term "dynamic" is used to refer to audio equipment, including headphones, microphones, and speakers. In musical terms, "dynamics" refers to the level of energy/loudness of a performance. Dynamic range is something to consider when it comes to headphones, but the word "dynamic" often means something different.

Dynamic earbuds have electronic drivers that convert audio signals into sound waves through electronic input. The coil/lead wire is connected to the diaphragm and suspended in a magnetic field. As the audio signal passes through the coil, the diaphragm moves and creates sound and delivers vibrant audio performance.

So, what is aptX and why does it matter?

It is an audio encryption code, developed in the late 1980s, popular in theaters and broadcasters. Steven Spielberg was an early adopter, working with aptX to record audio for 5.1 digital playback of films such as Jurassic Park in 1993, and later Schindler's List and Saving Private Ryan.

These days, aptX stands for Bluetooth, which you'll find in many computers, smartphones, AV receivers, and many other electronic devices.

But what does aptX do? It can stream music, at full bandwidth, at CD-like 16-bit/44.1kHz. Note that it's "CD-like" not "CD-quality" because aptX uses compression (which helps reduce audio transition times and reduces latency issues). It is designed to be better than standard Bluetooth.

The evolution to aptX Adaptive

aptX Adaptive, which may eventually replace aptX HD, combines the current aptX HD with aptX Low Latency, a codec that provides audio and video compatibility with less than 40 milliseconds of latency when watching a video and he is playing games with you.

Backwards compatible with aptX and aptX HD, aptX Adaptive takes into account the RF environment around your aptX compatible device, so you won't have to worry about it falling off when you take your phone out of your pocket or bag. It will automatically raise the volume depending on whether you are on a call or listening to music.

As the name suggests, aptX Adaptive is a codec designed to be adaptive. Instead of having a fixed bitrate like aptX Classic, Low Latency and aptX HD, the latest codecs can scale the bitrate to change and adjust its quality.

Bringing aptX Bluetooth and dynamic sound drivers together with Cleer ROAM SPORT

Now that you know what these two technologies are, you can already piece together the importance of the relationship between dynamic drivers and AptX Adaptive technology. The idea is to deliver a truly wireless sound experience with audio quality like never before.

Innovative earbuds much like Cleer ROAM SPORT feature both technologies to deliver a larger-than-life experience while on the go. Escape into a world of vibrant audio performance in noise cancelling earbuds with the soundtrack of your choice and live life to the fullest. Throw in the fact that these earbuds have up to 20 hours of battery life and a IPX4 water resistant rating, and you’ve got the ultimate lifestyle companion.

Power next-level sound with aptX Adaptive and dynamic audio drivers

At the end of the day, when you’re listening to music, you want to hear it the way the artist imagined it. The way it was meant to be heard. Unfortunately, some Bluetooth headphones are unable to transmit this type of high-quality sound.

The great news is that the newly launched Cleer ROAM SPORT features aptX Adaptive and dynamic drivers to ensure that you listen to your favorite sounds the way they should be heard – crystal clear and undistorted.
