In essence, a codec is the algorithm your device uses to send audio information over the air. Each codec varies in quality and can only be used with compatible pieces of hardware, such as speakers or headphones.Previously in Android Nougat and lower, users had no option to choose which codec was used in cases where multiple were available on your audio device. For audio enthusiasts, this new flexibility is a big improvement.The Galaxy S9 offers SBC, AAC, aptX, Samsung HD, and LDAC codecs. While SBC is the default option, it's incredibly easy to change to any of the above options. Let's take a quick look at changing the codecs, then run down what each offers.

What Each Bluetooth Audio Codec OffersHere's a quick summary of the available Bluetooth codecs on the Galaxy S9 to help you choose which is right for you. Remember, though, most Bluetooth accessories only support certain codecs, so check the user manual on your Bluetooth headphones or speakers to make sure the option you choose is supported.SBC: the standard mandatory Bluetooth audio codec. Varies in quality with respect to the connected headphones or speakers. Bit rate ranges between 192 and 320 kbps, typically considered the lowest quality compression available. AAC: Popular codec used in most streaming services, like YouTube. Many Apple products also support this codec. Compression quality around 250 kbps for transmission. atpX: Qualcomm's proprietary codec, saves on data rate compared to the previous methods. Transferring quality of 352 kbps. LDAC: Sony's proprietary Bluetooth codec. Has a wide range of quality options from 330 kbps up to 990 kbps. The highest quality option supports 24-bit, 96 kHz audio. This is generally considered one of the highest quality codecs, but is not available on as many pairs of headphones as the previous codecs. Samsung HD: Samsung's Proprietary codec. No public information available on specific bitrate. Available on all Samsung audio hardware.
Step 3: Configure Codec-Specific Options (Optional)In addition to manually switching codecs, there are a more Bluetooth settings of interest within Developer Options. If you went with the LDAC codec, for instance, there's an option to manually set the quality between the 330, 660, and 990 kbps modes. While this is nice for audiophiles, it is best to leave this to the system if you're unsure of your connection quality. If you're wondering whether or not your headphones support a particular codec, the technical specifications on the retail box or product page should have this information.
