Soledge

What Soledge does

Soledge is a privately held French company founded in 2010 in Montpellier by Raphaël Bini and two co-founders who were music and HiFi enthusiasts and engineers. The company specializes in embedded electronics and software for audio/video applications and communications networks, with a core focus on wireless multiroom audio. Its technology platform is built around two granted patents — AccuSync, which achieves less than 10 microseconds of speaker-to-speaker synchronization (versus a 40–50 microsecond human-ear detection threshold), and AccuRate, which provides syntonization to preserve dynamics and eliminate transmission distortion — combined with Power Line Communication (PLC) that transmits uncompressed audio over existing household electrical wiring. Products support lossless audio up to 24-bit/192kHz and integrate natively with AirPlay, DLNA, and HomePlug AV standards.

The company's commercial offering is structured in three tracks: a finished consumer hardware range (Ténor smart amplifier, Alto network player with integrated PLC, Maestro music server, and Canto multiroom audio system); an OEM module business selling three platforms (Amplified, Analog, and Digital streamer modules) to loudspeaker and consumer electronics manufacturers; and a technology licensing program that makes the patented AccuSync and AccuRate technologies available to companies with engineering and manufacturing capabilities. Customer segments include high-end audiophile consumers seeking to modernize legacy HiFi systems, connected-home users wanting whole-house audio, and consumer electronics manufacturers seeking embedded multiroom capability.

Operationally, Soledge is a micro-cap, founder-owned business with 1–10 employees, headquartered in Clapiers near Montpellier with a satellite office in Holstebro, Denmark (established 2016 as part of the Bang & Olufsen Hi-fi Valley program). Distribution relies on direct website sales, selective audio retail (e.g., Puresound in Belgium), and exhibition presence at major AV industry events including ISE Amsterdam (2016–2020) and CES Las Vegas (2015). No external funding rounds or institutional investors are disclosed in the available sources.

Core offering

Soledge designs and manufactures high-end connected wireless audio products (Ténor smart amplifier, Alto network player, Maestro music server, Canto multiroom system) using its patented AccuSync and AccuRate synchronization technologies and Power Line Communication (PLC). The company also sells OEM hardware/software modules and licenses its patented audio synchronization technology to consumer electronics manufacturers.

Product overview

Soledge offers a dual-track business model combining consumer products and technology licensing for manufacturers. The consumer product lineup includes the Ténor smart amplifier (transforms passive speakers into connected devices), Alto network player (with built-in PLC for powerline audio transmission), Maestro music server, and Canto multiroom system supporting high-resolution audio up to 24-bit/192kHz. All products feature patented AccuSync and AccuRate technologies for sub-10-microsecond speaker synchronization. For manufacturers, Soledge provides three module platforms (Amplified, Analog, and Digital streamer platforms) and technology licence agreements, enabling third-party brands to incorporate Soledge's synchronized multiroom capabilities into their own connected audio products.
