There will be a noticeable change in the audio quality of phone calls and music streaming via Bluetooth LE Audio. Wireless phone calls will provide up to 32 kHz sampling rate \u2013 that is twice as much bandwidth as before. This huge improvement will deliver a brighter, better-to-understand, and more lifelike sound. It is also a very important fact for the unbridled enjoyment of content with a lot of high-frequency information, like music, since LC3 delivers great quality even at lower data rates. In fact, the quality of LC3 exceeds the quality of the legacy Bluetooth Classic codec SBC while requiring only half its bitrate.<\/p>\n<p>LC3 \ucf54\ub371\uc5d0 \ub300\ud574\uc11c
