Wolfson Microelectronics was a UK-based fabless semiconductor company specializing in high-performance mixed-signal chips for digital consumer electronics. Founded in 1984 and headquartered in Edinburgh, Scotland, it became renowned for its audio and image technologies. The company's core product lines included high-performance audio codecs, power management ICs (Smart Power), active noise cancellation (Enhanced Soundware), and MEMS microphones (True Microphone) under its AudioPlus™ strategy. Wolfson's audio solutions were adopted by major brands such as Apple (iPod nano), Sony (PSP), and Microsoft (Xbox 360), establishing its leadership in premium audio for portable devices. Its products were widely used in smartphones, portable media players, tablets, gaming consoles, and automotive infotainment systems. Wolfson employed over 370 staff across 12 offices worldwide, with design centers in Edinburgh and sales support in the US, Japan, China, Taiwan, Korea, Singapore, and India. The company invested heavily in R&D to maintain technological leadership, achieving a threefold revenue increase over five years prior to its acquisition. In 2014, Wolfson Microelectronics was acquired by Cirrus Logic, combining two industry leaders in audio solutions. Today, Wolfson technology continues to serve customers as part of Cirrus Logic's portfolio, upholding its legacy of high-quality audio innovation.
