LDAC It is a Sony-owned wireless audio codec also made by the Japanese tech giant. Users who have purchased a pair of wireless Sony Over the last few years headphones have noticed that they claim to support LDAC. Here we will discuss What is LDAC?How it works and how it can affect the quality of wireless audio
What is LDAC?
As mentioned earlier, LDAC is a wireless audio codec developed by Sony. This audio codec differs from the old Bluetooth streaming technology. This codec uses a combination of harmless (when possible) and harmless compression to deliver high resolution audio.
How does it work?
Bitrate is a term used to describe the amount of data transferred to audio. A higher bitrate usually offers better audio quality. If you want to download or listen to music in physical audio format, you can afford a higher bitrate. On the other hand, if you are streaming music, you want to have a lower bitrate for effective streaming.
LDAC uses a different bitrate than older wireless audio technology. This codec uses bitrate rates of either 330/660 / 990kbps at the sample rate of 96 and 48kHz or 303/606 / 909kbps at the sample rate of 88.2 and 44.1kHz. These bitrates are higher than the old wireless audio technology. For example, Bluetooth Special Interest Group’s SBC uses a bitrate of 345kbps at 48kHz, while Qualcomm’s aptX uses a bitrate of 384kbps at 48kHz.
How does it affect wireless audio quality?
Sony promotes the technology as a truly wireless, high-resolution audio solution In fact, only a higher bitrate of 990kbps qualifies codec claims SoundGuys conducted an in-depth study of the technology and concluded that LDAC is not very successful in recording 24-bit / 96 kHz studio-quality recordings.
Other available high-resolution audio solutions
Other companies are trying to make high-resolution audio available in the world of wireless earbuds. In 2016, Qualcomm launched aptX HD, also known as aptX Lossless, to offer higher bitrate streaming of 576kbps on Bluetooth headphones compatible with technology.
Can LDAC be used by other brands?
Sony has developed the technology and continues to integrate it into LDAC products However, the LDAC encoder is open-source that allows manufacturers to incorporate technology into non-Sony products. From Android 8.0 “Oreo” released in 2017, LDAC Android is a part of the open source project.
This enables each OEM to integrate this standard freely into their own Android device. If you use an Android device running Oreo or above, you can use LDAC with compatible wireless audio products.
However, this audio codec is found in most Sony products, including wireless earbuds and headphones, among others. Other brands, such as Anchor Life, have adopted LDAC support on some of their headphones, and users can use the technology to listen to music on some gaming headsets.
Users can use LDAC on some selected wireless speakers, home theater setups, soundbars, dedicated portable audio players in the Walkman range, Bluetooth headphone amplifiers and even car receivers.
Currently, none of Apple’s products support LDAC and users are not able to use the higher bitrate that Codec supports with an iPhone, iPad or AirPods.
