What Bluetooth audio codec does Windows use?

Actually, we can find a wide variety of Bluetooth audio codecs in Windows. SBC (Subband Coding), AAC (Advanced Audio Coding), aptX and LDAC (Low Delay Audio Codec).

Although natively, Windows 11 only supports AAC and SBC:

  • SBC: This is a fairly basic codec, which was developed by the Bluetooth Standards Organization. This has a low depth rate of 16 bits, a maximum of 320 kbps, and a frequency of 48 kHz maximum.
  • CAA: Advanced Audio Coding is the one used for Apple devices. It has a sample rate of 44.1 kHz and a maximum bit rate of 320 kbps.
