Steinberg is a German musical equipment and software company. It mainly produces MIDI music sequencer software, software synthesizers and digital audio editing tools.

The company was founded in 1984 by Karl Steinberg and Manfred Rürup. Its first product was the MIDI sequencer Steinberg Pro 16 for the Commodore 64. The company has changed name from Steinberg Research to Steinberg Soft- und Hardware GmbH, and was active in the United States for some years as Steinberg North America, Inc. In January 2003, the company was acquired by US firm Pinnacle Systems, within which it operated as an independent company producing its products before being sold to Yamaha in December, 2004.

They have also specified the Audio Stream Input Output (ASIO) protocol which provides a low-latency communication link between digital audio software and professional sound cards, the Virtual Studio Technology (VST) an industry standard bringing studio technology into sequencer software, the Linear Time Base (LTB) protocol, and VST System Link (VSL) a network protocol which shares the resources of several computers on the same project.
