EastWest Sounds, founded by recording engineer Doug Rogers in 1988, is a Hollywood-based developer of virtual instruments and sample libraries used widely in music production, film scoring, television, and game audio. Co-producer Nick Phoenix joined Rogers in the late 1990s, and together they have built one of the largest catalogs of software instruments in the industry. The company owns and operates EastWest Studios (formerly Western Studios) on Sunset Boulevard in Hollywood, with additional software development offices in Berlin, Hamburg, and Munich.

EastWest's flagship products include the Hollywood Orchestra series (Hollywood Strings, Hollywood Brass, Hollywood Orchestral Woodwinds), the Symphonic Orchestra and Symphonic Choirs libraries, and genre-specific collections like Ministry of Rock, Stormdrum, and Fab Four. Their world music offerings include RA, Silk, Gypsy, and Ancient Kingdom. The company also produces vocal libraries such as Hollywood Choirs, Voices of Opera, and Voices of Soul, as well as synthesizer plugins like Forbidden Planet and ICONIC. EastWest's ComposerCloud+ subscription service provides access to over 43,000 virtual instruments across the full catalog.

The company has received over 120 industry awards, including multiple NAMM TEC Awards for Best Musical Instrument Software. EastWest Studios has hosted the recording or mixing of hundreds of Grammy-nominated projects. Notable composers and producers who use EastWest instruments include James Newton Howard, Danny Elfman, John Powell, Brian Tyler, Herbie Hancock, and Zedd.
