aptX Adaptive is a next-generation dynamically adjustable audio codec intended for premium audio quality and low-latency. aptX Adaptive's bitrate scales dynamically between 279 kbit/s and 420 kbit/s. It also works with a shared, rather than dedicated, wireless antenna. [ 36 ]
Low Latency High-Definition Audio Codec (LHDC) is an audio codec technology developed by Savitech.LHDC allows high-resolution audio streaming over Bluetooth.It is a high-quality Bluetooth codec based on the A2DP Bluetooth protocol and allows a bit-rate of up to 900 kbit/s compared to SBC's bit rate of 345 kbit/s .

LDAC is an alternative to Bluetooth SIG's SBC codec. Its main competitors are Huawei's L2HC, Qualcomm's aptX-HD/aptX Adaptive and the HWA Union/Savitech's LHDC. [1]LDAC utilizes a type of lossy compression [2] [3] by employing a hybrid coding scheme based on the modified discrete cosine transform [4] and Huffman coding [5] to provide more efficient data compression.
The data compression software for encoding into ALAC files, Apple Lossless Encoder, was introduced into the Mac OS X Core Audio framework on April 28, 2004, together with the QuickTime 6.5.1 update, thus making it available in iTunes since version 4.5 and above, and its replacement, the Music application.

While designed for a one-way audio transfer - CSR has developed a way to transfer a mono stream back (and enable use of headsets with microphones), and incorporated it into FastStream and aptX Low Latency codecs. The patent has expired. Some Bluetooth stacks enforce the SCMS-T digital rights management (DRM) scheme. In these cases, it is ...
