A sound card is an internal expansion card that provides input and output of audio signals to and from a computer under the control of computer programs. The term sound card is also applied to external audio interfaces used for professional audio applications.
Dolby Digital, originally synonymous with Dolby AC-3, is the name for a family of audio compression technologies developed by Dolby Laboratories. Called Dolby Stereo Digital until 1995, it is lossy compression. The first use of Dolby Digital was to provide digital sound in cinemas from 35 mm film prints. It has since also been used for TV broadcast, radio broadcast via satellite, digital video streaming, DVDs, Blu-ray discs and game consoles.
Sound Blaster is a family of sound cards and audio peripherals designed by Singaporean technology company Creative Technology. The first Sound Blaster card was introduced in 1989.
A sampler is an electronic musical instrument that records and plays back samples. Samples may comprise elements such as rhythm, melody, speech, sound effects or longer portions of music.
Pro Tools is a digital audio workstation (DAW) developed and released by Avid Technology for Microsoft Windows and macOS. It is used for music creation and production, sound for picture and, more generally, sound recording, editing, and mastering processes.
The Environmental Audio Extensions are a number of digital signal processing presets for audio, present in Creative Technology Sound Blaster sound cards starting with the Sound Blaster Live and the Creative NOMAD/Creative ZEN product lines. Due to the release of Windows Vista in 2007, which deprecated the DirectSound3D API that EAX was based on, Creative discouraged EAX implementation in favour of its OpenAL-based EFX equivalent – though at that point relatively few games used the API.
Ensoniq Corp. was an American electronics manufacturer, best known throughout the mid-1980s and 1990s for its musical instruments, principally samplers and synthesizers.
DirectSound is a deprecated software component of the Microsoft DirectX library for the Windows operating system, superseded by XAudio2.

The Ensoniq ESP was used in many of the company's musical instruments and on their Soundscape Elite PC ISA sound card. It was used to enhance the synthesizer's audio samples with digital effects, enhancing the realism of the overall sound.
The Ensoniq AudioPCI is a Peripheral Component Interconnect (PCI)-based sound card released in 1997. It was Ensoniq's last sound card product before they were acquired by Creative Technology. The card represented a shift in Ensoniq's market positioning. Whereas the Soundscape line had been made up primarily of low-volume high-end products full of features, the AudioPCI was designed to be a very simple, low-cost product to appeal to system OEMs and thus hopefully sell in mass quantities.
Sound Blaster Live! is a PCI add-on sound card from Creative Technology Limited for PCs. Moving from ISA to PCI allowed the card to dispense with onboard memory, storing digital samples in the computer's main memory and then accessing them in real time over the bus. This allowed for a much wider selection of, and longer playing, samples. It also included higher quality sound output at all levels, quadrophonic output, and a new MIDI synthesizer with 64 sampled voices. The Live! was introduced in August 1998 and variations on the design remained Creative's primary sound card line into the early 2000's.
Sound Blaster Audigy is a product line of sound cards from Creative Technology. The flagship model of the Audigy family used the EMU10K2 audio DSP, an improved version of the SB-Live's EMU10K1, while the value/SE editions were built with a less-expensive audio controller.
The Sound Blaster AWE32 is an ISA sound card from Creative Technology. It is an expansion board for PCs and is part of the Sound Blaster family of products. The Sound Blaster AWE32, introduced in March 1994, was a near full-length ISA sound card, measuring 14 inches (356 mm) in length, due to the number of features included.
McASP is an acronym for Multichannel Audio Serial Port, a communication peripheral found in Texas Instruments family of digital signal processors (DSPs) and Microcontroller Units (MCUs).
