Intel High Definition Audio (IHDA) (also called HD Audio or development codename Azalia) is a specification for the audio sub-system of personal computers. It was released by Intel in 2004 as the successor to their AC'97 PC audio standard.
High-resolution audio (high-definition audio or HD audio) is a term for audio files with greater than 44.1 kHz sample rate or higher than 16-bit audio bit depth. It commonly refers to 96 or 192 kHz sample rates. However, 44.1 kHz/24-bit, 48 kHz/24-bit and 88.2 kHz/24-bit recordings also exist that are labeled HD audio.
AC'97 (Audio Codec '97; also MC'97 for Modem Codec '97) is an audio codec standard developed by Intel Architecture Labs and various codec manufacturers in 1997.

In addition to PCI and PCIe internal sound cards, Creative also released an external USB-based solution (named X-Mod) in November 2006. X-Mod is listed in the same category as the rest of the X-Fi lineup, but is only a stereo device, marketed to improve music playing from laptop computers, and with lower specifications than the internal offerings.
The Sound Blaster Audigy Fx (SB1570), released in September 2013, is a HDA card, it uses an ALC898 chip from Realtek, [16] includes a 600-ohm amplifier, Sound Blaster Audigy Fx Control Panel, EAX Studio Software, and independent line-in and microphone inputs. It is a half-height expansion card with a PCI Express ×1 interface.
Creative cards are generally backwards compatible with older EAX versions, although hardware accelerated DSP processing of these effects only happens on cards with EMU chips. Most audio solutions from Creative released after the X-Fi Titanium HD (except for the Audigy Rx) and other companies offer EAX software emulation of varying degrees instead.
