SoundNodes product offering
Product offeringCore offering
SoundNodes designs, assembles, and sells vertically integrated audio intelligence systems for broadcast operators, combining proprietary AI software (SoundID AI engine for fingerprinting, recognition, audience measurement, voice biometrics, and emotion detection), a broadcast software suite (CastLan automation, AudioSpy multi-channel recording, DigiPlan traffic scheduling), and purpose-built edge hardware (RadioSpy monitoring units, CapturHub 220, CapturHub Nano, CapturHub Nano POE). All products are designed and assembled in Brussels, Belgium, and deploy on-prem, in cloud, or at the edge for 24/7 mission-critical broadcast monitoring, content recognition, royalty tracking, and compliance.
Product overview
SoundNodes offers a unified platform-plus-modules architecture combining hardware edge nodes and AI software for broadcast operators. The core SoundID AI engine powers three main variants: Core (audio fingerprinting for asynchronous content recognition), Live (near-real-time recognition for live streams), and Audience (mobile-based audience measurement). Add-on modules Voice (speaker biometrics) and Mood (emotion detection) extend the platform. The software suite includes CastLan (broadcast automation), AudioSpy (multi-channel recording), and DigiPlan (traffic scheduling). Hardware products RadioSpy (radio monitoring), CapturHub 220 (professional capture), CapturHub Nano (desktop AI recorder), and CapturHub Nano POE (ceiling-mounted PoE recorder) provide edge capture nodes. All components are designed and assembled in Belgium, work together as an integrated system, and deploy on-prem, in cloud, or at the edge.

SoundNodes competitors and assessment
Company assessmentBroad incumbents
- Shazam (Apple): Apple-owned Shazam is the most recognized audio recognition platform globally. While consumer-facing rather than B2B broadcast, its underlying fingerprinting technology and massive reference database represent an indirect competitive force.
- Nielsen: Nielsen is the incumbent in audience measurement for linear media, with extensive panel infrastructure. SoundID AI Audience directly targets this market with a privacy-first mobile fingerprinting alternative to Nielsen's diary- and panel-based ratings.
Direct peers
- ENCO Systems: ENCO is a long-established broadcast automation and playout vendor serving radio and TV operators. Overlaps with SoundNodes' CastLan and AudioSpy lines in the same broadcast customer base.
- BMAT Music Innovators: BMAT is a Barcelona-based audio fingerprinting specialist focused on broadcasters, collecting societies, and rights organizations — a near-identical customer set to SoundNodes' rights associations and regulatory segments.
- Digimarc: Digimarc provides audio and digital watermarking/identification solutions for media, rights, and anti-piracy use cases. Comparable as an alternative identification approach to fingerprinting for broadcasters and content owners.
- WideOrbit: WideOrbit sells broadcast traffic, scheduling, and automation software to radio and TV groups. Competes in the same DigiPlan and DigiStation use cases at scale across large broadcast groups.
- RCS (Radio Computing Services / Zetta): RCS provides radio automation, traffic, and music scheduling software (Zetta, GSelector) to thousands of broadcast operators. Directly comparable to CastLan and DigiPlan in radio automation and scheduling.
- Comrex: Comrex is a US manufacturer of broadcast audio hardware for remote capture and live contribution. Most comparable to SoundNodes' CapturHub hardware line on the audio capture/appliance side.
- Audible Magic: Audible Magic is a US-based audio and video content identification company serving broadcasters, UGC platforms, and rights holders. Directly comparable as a content recognition vendor for broadcast and media use cases.
- Gracenote (Nielsen): Gracenote, owned by Nielsen, is the leading provider of audio and music fingerprinting for broadcasters, streaming services, and rights organizations. SoundNodes competes head-on in audio content recognition and audience measurement, but against a much larger incumbent with deeper reference databases.
