What is SBC / AAC？

SBC (Subband Coding) and AAC (Advanced Audio Coding) are audio codecs used for compressing and transmitting digital audio, particularly in Bluetooth devices. SBC is standard, while AAC offers higher quality at lower bitrates.

Simply Put:

Think of SBC and AAC like packing lunch. SBC is like throwing a sandwich in a bag, quick and takes up little space but might get a bit squished. AAC is like carefully packing the same sandwich in a nice box, it stays fresh and neat but still fits in your bag.
