Wheatstone unveiled its Neuron FM/HD/DAB+ spectral audio processor at the 2025 NAB Show.

The processor brings more energy to the FM band.

With more choices in audio delivery and listening devices today, Neuron’s spectral approach to audio processing is designed to bring new life to radio – and radio listeners.

Neuron FM/HD/DAB+ spectral audio processor uses patented 1/3 octave band resolution for precision transient peak control without pulling down critical frequencies with it. The result is the ability to drive more energy into the processor, yet maintain peak compliance for a much fuller, vibrant on-air sound.

The new spectral audio processor uses proprietary Density Compensation® algorithms for real-time analysis of the pre- and post-processed audio as well as data from the user’s control settings to invisibly manage spectral balance and program density across the range of program content today.

Also included in the Neuron FM/HD/DAB+ audio processor are: pre-emphasis optimization, multipath mitigation, and RDS/RBDS generator, SCA and stereo generator, plus Wheatstone® baseband192 for digitizing the multiplex spectrum.

Neuron is WheatNet IP compatible and has smart settings for exponentially enhancing control settings to create a signature sound in minutes, not days or hours.

At NAB, Wheatstone also released version 5.0 of NAVIGATOR software for its WheatNet IP audio network.  The update adds new network I/O diagnostics, failover management, automatic system backup advancements and extends logic status to third-party devices, among other advancements. NAVIGATOR is the management software for WheatNet IP audio networks and includes  tools for setting up crosspoints, logic signals, AES67 paths, salvos, and SNMP alerting across multiple locations.
