Elytone NAP1 Platform Improves with AES67 and AES70 (OCA) Support

Elytone returned to ISE 2025 in Barcelona with another series of exciting technology updates in networked audio. The Taiwan-based company showcased new developments featuring its Networked Audio Processor 1 (NAP1) platform enabling IP audio networks over Dante and AES67, now with AES70 (OCA) controls, enhanced A2B Audio Bus bridging (including automatic plug & play). Also new is the addition of audio streaming capabilities, including Spotify Connect and Google Cast, with more streaming services in final testing and additional services to be added in 2025.
The capabilities of Elytone’s high-performance Networked Audio Processor 1 (NAP1) continue to expand with more options for applications and products that audio brands can deliver with this powerful module. NAP1 is a core application processor for a wide variety of products – a complete Linux system running on Analog Devices ADSP-SC598 System on Chip (SoC). It incorporates an ARM A55 Cortex core, dual-core high-performance SHARC audio DSPs with high on-board DDR3 memory, SPI Flash Quad memory, and audio I/O connectivity for peripherals.
At ISE 2025, the company’s Networked Audio Video products group showcased an AES67 multichannel audio network of a 7.1 surround system, all enabled by the Elytone NAP1 platform. Early development of AES70 (OCA) remote device controls over the AES67 network is another area of interest. As part of this system, Elytone also demonstrated multichannel networked amplifiers with amplification and power supply modules from its own Peak Amplification brand. This NAP1-driven amplifier uses Peak Amplification modules from the Flexible line.

With this implementation of AES67, Elytone is now able to provide up to twice the number of IP audio channels due to the lean run-time code of AES67. This means up to 64×64 simultaneous channels of 16-bit @48kHz audio, while multi-clock and multi-sample rate issues are solved with precise time-stamping and multiple ASRCs within the SoC. Licensing structure and pricing directly with Elytone for AES67 is very lean, in keeping with the code, and the company can deliver NAP1 ready for Dante, AES67, or both, with end users able to select the protocol at boot-up, the company confirms.
One of the exciting areas of research for the Elytone team is the integration of AES70 (Open Control Architecture) on NAP1, supporting both AES67 and Dante. Already with its earlier efforts, Elytone reports successful results with AES70, allowing for local LAN and Internet-based remote monitoring and control of devices across a wide range of IP media environments. At ISE, Elytone demonstrated synchronized volume control across a network of devices.

Based on these results, in 2025 Elytone will be expanding AES70 capabilities on NAP1, including but not limited to AES67 stream discovery and connections, device telemetry, parameter-based alerts, and more. This means a fully functional networking solution based on both AES standards, of great interest to a range of product developers and manufacturers in the residential, commercial integration, and even content production markets. Elytone also confirms that, in 2025, NAP1 will be able to receive direct audio streaming to the module as inputs.
“These new capabilities are important for audio brands who want to develop sophisticated networked audio products with extremely efficient development times and teams. NAP1 is developed to dramatically shorten and simplify what is needed to get a complete networked processor running for a wide range of applications, allowing teams to focus on unique features and sound, not spending time on the complexity of integrating audio functions, DSP, networking, protocols, and certifications,” says Jason Nims, Vice President, Strategy and Marketing at Elytone Electronics.

As Elytone confirmed to audioXpress, in 2025, NAP1 will also be able to receive direct audio streaming to the module as inputs, allowing Spotify Connect and Google Cast, and more services in final testing (e.g. AirPlay) to be processed and used within an audio product, such as a media processor, amplifier, or speaker, or passed into Dante or AES67 networks. This significantly expands the potential for NAP1 to act as the complete core of many advanced audio products receiving both local audio sources and streamed audio sources and services, advanced processing of audio signals via DSP, and multiple options for audio output and networking.
At the time of publication, Elytone is demonstrating all these advances at ISE 2025, in Hall 5 booth 5Q500. At the booth, Elytone is also showcasing A2B and Power Over Ethernet demonstrations, together with the company’s latest Peak Amplification Class-D products.
