LDAC™ is a different audio technology from Sony that enables you to have high-quality wireless audio via Bluetooth.
Including 3x the data transferred, LDAC gives an improved wireless listening knowledge for collecting your music.

What is LDAC?

In addition to the undisputed convenience, the popularity of Bluetooth wireless audio streaming devices also lies in the increasingly improved connection quality. This was made possible by the emergence of the first new generation of Bluetooth codecs, LDAC. So what is LDAC, and how does it affect your listening experience? Let’s find out right here.

LDAC is an established audio coding technology produced by Sony, which provides flowing high-resolution audio over Bluetooth links at up to 990 kbps at 32 bit/96 kHz. It is handled by various Sony products, including headphones, smartphones, compact media players

If you own Sony’s new generation of Bluetooth headsets, music players, or smartphones, you must have seen information related to LDAC. LDAC is a wireless audio codec (Wireless Audio Codec) exclusively researched, developed by Sony, and introduced in 2015. Sony has never announced LDAC stands for the phrase. What, so it can be understood that this is the proper name of this technology.

The LDAC codec differs from conventional Bluetooth streaming technologies. It uses a combination of lossless compression and lossy compression solutions in each given usage scenario to deliver high-resolution audio sound to the listener’s ear.

This codec offers bit rates of 330/660/990kbps at 96 and 48kHz sample rates or 303/606/909kbps for 88.2 and 44.1kHz sampling rates. All of which outperform the bitrates commonly found on older technologies like Bluetooth Special Interest Group SBC (345kbps at 48kHz) or Qualcomm’s aptX (384kbps at 48kHz), thus resulting in better audio quality.
As announced by Sony, LDAC offers efficient encoding and “optimized speed,” allowing you to transfer 3 times more data than existing audio codecs.

Of course, LDAC isn’t the only attempt at bringing high-resolution audio to the world of wireless headphones. Qualcomm introduced aptX HD (also known as aptX Lossless) in 2016 to enable higher bitrate streaming of 576kbps on compatible Bluetooth headsets. However, this number is still lower than that of LDAC.

Where is LDAC located?

Although Sony is the sole LDAC research and development unit, this Codec is still basically open source. This has resulted in LDAC being included in many other non-Sony products, including Android 8.0 “Oreo” released in 2017. If you have an Android device running Oreo, you can use it. LDAC with compatible wireless products.

Since Sony develops LDAC, you will find LDAC support in most Sony Bluetooth headset products. It can be drawn as the newly released WF-1000XM4 and WH-1000XM4 wireless headphones. In addition, some other manufacturers have also integrated LDAC on their headphone products to provide better sound quality.

You can also use LDAC with some models of active wireless speakers, home theater and soundbar setups, dedicated portable music players, Bluetooth amplifiers (like the FiiO BTR3), and even receivers on cars like Kenwood KKX9020DABS.

Currently, there is no LDAC support in any Apple products, so you won’t be able to take advantage of LDAC on headphones and speakers that support this Codec when connecting them to iPhones, iPads, and vice versa. In addition, many other popular wireless earbuds (like the Jabra Elite 75t) also do not support LDAC but use other Codec standards. Therefore, if you like and want to use LDAC, you should carefully research the product before buying, see if it is supported or not.

How to Enable LDAC on Android

Many Android devices support LDAC, but this feature needs to be enabled manually rather than by default. To do this, first enable developer options on your Android phone. Then go to Settings > Developer options > Bluetooth Audio Codec. Here you can select LDAC from the available list.

How Can You Use LDAC?

While Sony produced the technology and advances to sell its products, the LDAC encoder is the public source. That has led to many more outputs, including the Android 8.0 “Oreo” released in 2017. If you have an Android device that runs Oreo, you can likely use LDAC with compatible wireless products.
