What is an apt codec?

It is an audio coding algorithm that was created in the 1980s. Nowadays, the apt codec is almost synonymous with Bluetooth, which can be found in computers, smartphones, AV amplifiers, and a host of other consumer electronics products.

Why is apt good?

Because it can transmit the full bandwidth of music files in “CD-like” resolution, i.e. 16-bit / 44.1 kHz. It is “CD-like” and not “CD-quality” because apt performs a compression that helps reduce audio encoding delays and minimizes latency. The classic apt has a compression ratio of 4: 1 and a data rate of 352kbps.

Why are apt HD, apt Low Latency, apt, SBC codecs so good under Bluetooth?

Apt HD (and other codecs) is essentially an updated and improved apt to make wireless audio quality even better. The codec was developed by Qualcomm to spread the growing popularity of Hi-Res Audio. Its data rate is already 576kbps.
