Accusonus is a Greek audio technology company founded in 2013 by Alex Tsilfidis and Elias Kokkinis in Patras, Greece, with additional offices in Athens and Lexington, Massachusetts. The company specializes in AI and machine learning-driven audio processing software, developing plugins and standalone tools for music producers, mixing engineers, podcasters, and video creators.

Accusonus is best known for its ERA Bundle, a suite of single-knob audio repair plugins including Noise Remover, Reverb Remover, De-Esser, Plosive Remover, Voice Leveler, De-Clipper, and Voice AutoEQ — designed to make audio cleanup fast and accessible without deep technical expertise. The company also developed Regroover, a virtual instrument plugin that uses machine learning to deconstruct audio loops into their component stems for remixing and sampling, and Drumatom, a standalone application for removing microphone bleed from multi-track drum recordings. Other products include Beatformer, a beat-shaping processor, and Rhythmiq, a percussion synthesis tool.

Both founders hold PhDs in Audio Signal Processing, and the company's products are built on patented machine learning technology that originated from their academic research. Accusonus carved out a niche as a pioneer in applying AI to practical audio repair and music production workflows, earning a reputation for making complex signal processing tasks approachable through simplified, single-knob interfaces.

Accusonus has 7 products cataloged on Equipboard, including Audio Restoration Plugins, FX Bundle Plugins, and Sampler Plugins. Their gear is featured by 1 artist, with the strongest followings in Electronic. Notable users include The Midnight.
