We all are known about Bluetooth technology which is a hardware and helps to transmit our data and various types of files wirelessly. But now we describe APTX technology. APTX technology invented the famous chipset manufacturer Qualcomm and its known in the technology family Qualcomm APTX. The meaning of APTX is “Advanced Process and Technology Experiment “.

What is Bluetooth codec?

A codec determines the way Bluetooth is transferred from the source to headphones. The source may be a computer, tablet, smartphone, and more others. Codec is needed for encoding & decoding digital sound data to a specific format. Moreover, the main goal is to transfer a high-fidelity signal at a small bit-rate. This will help in minimizing space & bandwidth necessities for playback and storage.

Low bit-rate results in superior compression & reduced sound quality. Additionally, a high bit-rate leads in less compression & greater sound quality.

Types of Bluetooth Codec

More types of Bluetooth codecs exist. The major ones include LDAC, Apt-X, Apt-X HD, AAC & SBC. With these codecs, it’s simple to identify the max-rate acceptable when transmitting the signal & output audio quality. Below are features of AAC and aptX Bluetooth codecs.

What is AAC audio format?

AAC stands for advanced audio coding. It is a standard for lossy-digital sound compression. Furthermore, it’s also a license-free standard for YouTube & Apple’s favorite transfer mode. iPhone customers appreciate more from AAC’s hi-resolution playback. It has a transfer rate of up to 250kbps.

Additionally, Android also supports AAC. This codec has an underwhelming performance. The reason being of inconsistent streaming-quality. Moreover, Android OS is yet to offer on a universal method of dealing with AAC. Additionally, this is a power-hungry codec that Apple OS is capable of managing. This is because of its gate-kept ecosystem.

What is Aptx?

Actually, Aptx delivered the wires’ quality sound wirelessly. Aptx support 48kHz / 16bit LPCM audio data means 352 KBPS. Also, Supports a latency of less than 130ms. AptX is used to improve the audio quality in all kinds of products including wireless speakers, headphones, and soundbars.

What is APTX Codec?

This Bluetooth codec is available in two forms. They include Apt-X HD and Apt-X. It’s a more used codec. It offers high transfer quality using a quantity of 350-Kb using apt-X and 576-Kb using apt-X HD Additionally, with audio compression, this method is fading i.e. information is erased. Although the playback is very noble. Apt-X codec (HD) is developed by Qualcomm Company. Moreover, this company also markets the apt-X HD chip. This gives a quality near to that of CD.

When listening, one will notice pleasant aeration & a broad frequency response. People with devices that use Apple OS won’t be able to enjoy the apt-X codec.

What Is Aptx HD?

Aptx HD is the recent development of Qualcomm Even this codec delivered more impressive audio quality. Aptx HD support 48kHz / 24bit LPCM audio data means 576kbps. Qualcomm aptX HD audio ensures your Bluetooth wireless-enabled device can deliver High Definition (HD) audio. It preserves sound data through the audio transmission, resulting in a ‘better-than-CD’ listening experience.

Bluetooth audio transfer is integrated into tablets, smartphones, laptops, headphones, and more other devices. The best good reason, this remains the best method to play audio. Bluetooth technology doesn’t need a connection to a home network for it to operate. Additionally, Bluetooth transmission steadiness has enhanced over the different generations’ versions. Moreover, Bluetooth controllers are capable of high data-rates and power efficient. This is useful when transmitting audio.

How Bluetooth Audio Transmission Operates

When two devices are connected, they’ll present to each other & list individual abilities. With audio transmission, no less than five compression-modes are possible. This choice is made by a chip that determines the transmission mode to be used. Additionally, if frequency conditions permit it the most qualitative-mode is auto chosen.

Moreover, when this state deteriorates, transmitters & receivers adjust & change it’s communication methods. Furthermore, the apt-X HD-codec is then moved to a low-quality codec.

AptX Technology Supported Headphone Brand List:

Above 60 plus manufacturer is now using Aptx HD codec now. But very shortly maximum manufacturer will introduce APTX HD with their product. Below few brands and their model which are using APTX HD

Conclusion

In summary, Apple has chosen the AAC-audio compression codec. It’s also the chosen format for use with iTunes & Apple Music. Moreover, the performance of AAC on android devices is unreliable thus not suitable. Thus you will use aptX HD and aptX codecs on Android OS.
