Codecs & technologyWhat Is a DAC? Digital-to-Analog Conversion, Explained
A DAC, short for digital-to-analog converter, turns digital audio, a stream of numbers, into the analog voltage that headphones and speakers play.

The numbers that separate good converters from mediocre ones are signal-to-noise ratio near 120 dB, THD+N around -120 dB, and input headroom such as 32-bit/384 kHz. A dedicated DAC earns its place when the built-in one hisses or flattens detail.

Codecs & technologyBluetooth DAC Guide: What It Does and How to Choose One
A Bluetooth DAC is the digital-to-analog converter inside a wireless receiver, and its quality sets the noise floor of the whole wireless chain. Judge one by published numbers: a named chip such as the ESS ES9018K2M, THD+N near -120 dB, dynamic range near +127 dB, and LDAC feeding it at up to 990 kbps. Then match the outputs, XLR, RCA, or optical, to your system. Capable units run $40.99 to $109.
