High-resolution audio

High-resolution audio, also known as High-definition audio or HD audio, is a marketing term used by some recorded-music retailers and high-fidelity sound reproduction equipment vendors. It refers to higher than 44.8 kHz sample rate and/or higher that 16-bit linear bit depth. It usually means 96 kHz (or even much higher), sometimes informally written as "96k", meaning 96,000 Hz which is outside of the hearing range of any human ear.
