Beyond Basic Audio: Mastering the SBC Codec.
SBC, the Low-complexity Subband Codec, is the mandatory Bluetooth audio codec built into every device: it streams at roughly 328 kbps (bitpool-dependent, 192–345 kbps) and favors efficiency over fidelity. It is fine for calls and casual listening, while aptX, AAC, or LDAC deliver better quality when both devices support them.
