Hello iQOOans,

Good Morning😊..

Today is the First day of October month and another new day also😊. This time again, i am come up with another very interesting tech topic "AAC and aptX Codec" related to audio quality. The main reason for discussing Bluetooth audio 🎶 codecs is the fact that Bluetooth is the future of wireless headphones and earbuds now.

So, without further delay let's start this topic in detail.

What is AAC Codec?

The AAC extension is short for “Advanced Audio Coding”, which is a standard audio container format for compressed digital audio and music data. Improved in several aspects, this format produces better sound quality at the same bitrate compared to the older audio formats.

Advanced Audio Coding is an audio coding standard for lossy digital audio compression. Designed to be the successor of the MP3 format, AAC generally achieves higher sound quality than MP3 encoders at the same bit rate.

The AAC family of audio codecs comprises some of the most efficient audio coding technologies available today. Standardized by ISO MPEG, it is designed to provide high quality audio at lower bit-rates than previous MPEG audio coding formats.

What is aptX?

aptX is a family of proprietary audio codec compression algorithms owned by Qualcomm, with a heavy emphasis on wireless audio applications . Qualcomm aptX is the most commonly supported audio codec found in headphones and smartphones. It compresses and decompresses audio as it travels from a source device to a receiving device.

The aptX is an audio codec that provides high definition voice quality over a connection using Bluetooth wireless technology. It is a bitrate efficient technology that makes sure you receive high quality audio from your Bluetooth device for a better listening experience. 

Difference between AAC and aptX codec:

Which codec is better AAC or aptX?

The aptX HD audio codec is the codec generally used for Android compatible device, while AAC is the high-quality codec recommended for Apple users. Now a days AAC codec is used in android also. However, the sound quality also depends on the hardware or actual specifications of the source and receiving device.

Other Bluetooth codecs:-

-Low-complexity sub-band codec (SBC)

-Qualcomm aptX, aptX LL, aptX HD, and aptX Adaptive.

-Advanced audio coding (AAC)

-Sony LDAC.

-HWA Alliance's LHDC and LLAC codecs.

-Samsung Scalable Codec.
