It was designed to balance reasonable audio quality with low computational complexity and bandwidth limitations typical in Bluetooth audio transmission. SBC supports up to 48 kHz sampling frequency, uses 4 or 8 subbands, and can handle bitrates up to 320 kbps for mono and 512 kbps for stereo streams. It divides the audio signal into multiple frequency bands and encodes each independently, allowing universal compatibility but resulting in significant compression and some audio quality loss compared to more advanced codecs <sup class='quote-ref' data-quote='11'>[11]<\/sup> <sup class='quote-ref' data-quote='13'>[13]<\/sup>.<\/p>\n<p>In 2025, SBC continues to be widespread especially in devices that do not implement higher-quality or proprietary codecs like aptX, LDAC, or AAC.
