Advanced Audio Coding (AAC) is an audio coding standard for lossy digital audio compression. It was developed by Dolby, AT&T, Fraunhofer and Sony, originally as part of the MPEG-2 specification but later improved under MPEG-4. AAC was designed to be the successor of the MP3 format (MPEG-2 Audio Layer III) and generally achieves higher sound quality than MP3 at the same bit rate. AAC encoded audio files are typically packaged in an MP4 container most commonly using the filename extension .m4a.

The basic profile of AAC (both MPEG-4 and MPEG-2) is called AAC-LC (Low Complexity). It is widely supported in the industry and has been adopted as the default or standard audio format on products including Apple's iTunes Store, Nintendo's Wii, DSi and 3DS and Sony's PlayStation 3. It is also further supported on various other devices and software such as iPhone, iPod, PlayStation Portable and Vita, PlayStation 5, Android and older cell phones, digital audio players like Sony Walkman and SanDisk Clip, media players such as VLC, Winamp and Windows Media Player, various in-dash car audio systems, and is used on Spotify, Google Nest, Amazon Alexa. Apple Music, YouTube and also YouTube Music streaming services. AAC has been further extended into HE-AAC (High Efficiency, or AAC+), which improves efficiency over AAC-LC. Another variant is AAC-LD (Low Delay).

The PlayStation 3 (PS3, initially stylized in all caps) is a home video game console developed and marketed by Sony Computer Entertainment (SCE). It is the successor to the PlayStation 2, and both are part of the PlayStation brand of consoles. The PS3 was first released on November 11, 2006, in Japan, followed by November 17 in North America and March 23, 2007, in Europe and Australasia. It competed primarily with Microsoft's Xbox 360 and Nintendo's Wii as part of the seventh generation of video game consoles.

The PlayStation 3 was built around the custom-designed Cell Broadband Engine processor, co-developed with IBM and Toshiba. SCE president Ken Kutaragi envisioned the console as a supercomputer for the living room, capable of handling complex multimedia tasks. It was the first console to use the Blu-ray disc as its primary storage medium, the first to be equipped with an HDMI port, and the first capable of outputting games in 1080p (Full HD) resolution. It also launched alongside the PlayStation Network online service and supported Remote Play connectivity with the PlayStation Portable and PlayStation Vita handheld consoles. In September 2009, Sony released the PlayStation 3 Slim, which removed hardware support for PlayStation 2 games (though limited software-based emulation remained) and introduced a smaller, more energy-efficient design. A further revision, the Super Slim, was released in late 2012, offering additional refinements to the console's form factor.

The PlayStation 4 (PS4) is a home video game console developed by Sony Interactive Entertainment. Announced as the successor to the PlayStation 3 in February 2013, it was launched on November 15, 2013, in North America, November 29, 2013, in Europe, South America, and Australia, and on February 22, 2014, in Japan. A console of the eighth generation, it competes with Microsoft's Xbox One and Nintendo's Wii U and Switch.

Moving away from the more complex Cell microarchitecture of its predecessor, the console features an APU from AMD built upon the x86-64 architecture, which can theoretically peak at 1.84 teraflops; AMD stated that it was the "most powerful" APU it had developed to date. The PlayStation 4 places an increased emphasis on social interaction and integration with other devices and services, including the ability to play games off-console on PlayStation Vita and other supported devices ("Remote Play"), the ability to stream gameplay online or to friends, with them controlling gameplay remotely ("Share Play"). The console's controller was also redesigned and improved over the PlayStation 3, with updated buttons and analog sticks, and an integrated touchpad among other changes. The console also supports HDR10 high-dynamic-range video and playback of 4K resolution multimedia.

PlayStation Store (PS Store) is a digital distribution service for users of Sony's PlayStation 3, PlayStation Vita, PlayStation 4 and PlayStation 5 game consoles via PlayStation Network.

The store offers a range of downloadable content both for purchase and available free of charge. Available content includes full games, add-on content, playable demos, themes and game/movie trailers.

Media Go is a media player and media library application software that runs on Microsoft Windows. It organizes and plays a wide variety of multimedia content including video, music, podcasts and photos, and can share them in a network as a DLNA server. Media Go also manages content on various Sony mobile devices including the PlayStation Portable, PlayStation Vita, Walkman, Sony Tablet, and Xperia. Gracenote tagging is integrated, and in the past it also had a storefront from PlayStation Network and mora for purchasing media content.

The software was offered by Sony Network Entertainment International, which later became Sony Interactive Entertainment. They announced the discontinuation of Media Go in December 2017; it was replaced by Music Center for PC which only works with audio products like Walkman.
