Understanding Codecs
To better grasp LDAC, let's first dive into codecs. A codec is a compression technology aimed at reducing the size of large files, comprising an encoder to compress files and a decoder to decompress them. We can codec data (PKZIP), static images (JPEG, GIF, PNG), audio (MP3, AAC), and video (Cinepak, MPEG-2, H.264, VP8).

Codecs help encode large files like movies, audio, etc., resulting in faster file transfer and download speeds compared to conventional methods. This saves you time, effort, and enhances efficiency.
Deciphering LDAC
According to Sony, LDAC is an audio encoding technology or a Bluetooth codec that enables high-resolution audio transmission over Bluetooth connections. Essentially, LDAC is a proprietary Wireless Audio Codec developed and introduced by Sony in 2015.

LDAC enables transmission of data up to about three times more than other technologies over Bluetooth wireless networks with unprecedented sound quality, achieved through efficient encoding and optimized speed.
The Advantages of LDAC
Firstly, it brings superior audio quality to you. LDAC allows transmission of audio content, including high-resolution audio, with a maximum bit rate of 990kbps even over Bluetooth. LDAC is a codec certified as 'Hi-Res Audio Wireless'.

The 'Best Effort' mode helps automatically control the bit rate depending on network conditions, ensuring stable connections even in harsh environments. The bit rate automatically adjusts between 330kbps / 660kbps / 990kbps. LDAC is compatible with various devices as it is a software codec.

The LDAC source code has been contributed to the Android Open Source Project, allowing OEMs (Smartphone) to install LDAC software for free with permission from Sony. LDAC operates as the top connectivity priority for the Android operating system.
Devices Supporting LDAC
Firstly, we need to mention Sony devices such as Walkman music players, headphones, wireless speakers, Sony Xperia phones, and more.
Currently, there are quite a few audio devices supporting LDAC.
