Steinberg is a Hamburg, Germany-based music technology company founded in 1984 by Karl Steinberg and Manfred Rürup. The company is responsible for two technologies that became global industry standards: VST (Virtual Studio Technology), introduced in 1996, which defined the plugin format for software audio effects and virtual instruments now used across virtually every major DAW; and ASIO (Audio Stream Input/Output), a low-latency audio driver protocol. Both technologies were released as open standards, enabling adoption across the entire industry. Steinberg was acquired by Yamaha Corporation in 2004 and operates as a wholly owned subsidiary.

The company's flagship product, Cubase, first released in 1989 as a MIDI sequencer and expanded to include digital audio recording and VST support, is one of the most widely used DAWs in professional music production worldwide. Nuendo, introduced in 2000, is a DAW tailored for broadcast, film, and post-production workflows. WaveLab, launched in 1995, provides dedicated audio editing and mastering capabilities. Dorico, released in 2016, is a professional music notation and scoring application. HALion is the company's flagship software sampler, and VST Live Pro is aimed at live performance scenarios.

Beyond software, Steinberg has produced hardware including the UR series of USB audio interfaces and MIDI controllers, designed to integrate closely with its software ecosystem. With millions of users globally, Steinberg's tools are found in professional recording studios, broadcast facilities, educational institutions, and home setups alike.

Steinberg has 152 products cataloged on Equipboard, including Audio Interfaces, DAW Software, and Virtual Instrument. Their gear is featured by 525 artists, with the strongest followings in Electronic, Rock, and Pop. Notable users include Antoine Clamaran, David Wise, and Bustre. Steinberg's catalog spans the full price spectrum — from entry-level options to high-end flagships.
