Mercuriall Audio is a small Russian company, founded by programmer Vladimir Titov and sound engineer Vyacheslav Tikhonov in 2015.

The main goal of the company is to create software for artists and studios, precisely modeling analog devices. The modeling technology includes State-Spice simulation of electric circuits and Machine Learning for approximation of solving complex non-linear equations in real time. During the development process in the electrotechnical laboratory, each hardware device is thoroughly studied and a digital model is created afterwards.

The unique components of Mercuriall's digital models are the nearly identical dynamics of the sound and the harmonic spectrum of the analog amplifiers, which are the most crucial requirements for the artists.
