AES67 is an interoperability standard for high-performance audio-over-IP (AoIP) networks, enabling seamless audio transport between devices from different manufacturers. While the standard itself defines the technical requirements for synchronisation, packetisation, and transport, practical mastery demands more than reading the specification. Audio engineers working with AES67 must understand network design, Quality of Service (QoS), Precision Time Protocol (PTP), and redundancy topologies. Specialised training and certification programmes fill this gap, providing structured pathways to build, validate, and demonstrate expertise. This article explores the landscape of training and certification options, helping engineers choose the right programme for their career stage and technical environment.

Why Certification Matters

Certification offers tangible proof of competence in a field where network misconfigurations can cause audio dropouts, latency issues, or complete system failure. For employers, a certified engineer reduces risk. For engineers, certification opens doors to higher-profile projects and positions. According to the Audio Engineering Society, certified professionals are more likely to be considered for lead roles in broadcast, live sound, and installation projects.

Beyond career advancement, certification ensures adherence to industry best practices. AES67 networks often interconnect with Dante, Ravenna, Q-LAN, and other AoIP ecosystems. A certified engineer understands how to configure PTP domains, manage packet prioritisation, and troubleshoot at a protocol level. This knowledge leads to more reliable, scalable installations. Furthermore, manufacturers such as Lawo, Yamaha, and Audinate actively recommend or require certified personnel for system commissioning and support, reinforcing the value of formal credentials.

Available Training Programmes

Training options range from self-paced online modules to intensive hands-on workshops. The depth and focus vary, so engineers should evaluate programmes based on their existing experience and the specific demands of their work environment. Below are the major providers and the type of training they offer.

AES Academy

The Audio Engineering Society runs the AES Academy, which includes a dedicated suite of courses on AES67 and AoIP networking. These courses cover network fundamentals, PTP timing, stream setup, and troubleshooting with tools like Wireshark. The AES Academy offers both online modules with video lectures and quizzes, and in-person workshops at AES conventions and partner locations. The online format allows flexible pacing, while the workshops provide lab access to real switches, endpoints, and monitoring software. The AES67 course is a prerequisite for the AES Certified Audio Engineer exam, making it a natural starting point for serious candidates.

AVIXA

AVIXA (Audiovisual and Integrated Experience Association) is the leading trade association for the AV industry. Its training programme includes the Certified Technology Specialist (CTS) certification, which covers broad AV networking. AVIXA also offers focused courses on AoIP standards, including AES67, within its Pro AV curriculum. The training emphasises design, installation, and integration rather than deep protocol analysis, making it ideal for engineers who work in systems integration and need to merge AES67 with other AV signals. AVIXA’s online learning portal includes recorded webinars, downloadable guides, and live virtual sessions.

Manufacturer-Specific Training

Many equipment manufacturers run their own training academies, often with modules that cover AES67 in the context of their product lines. Examples include:

  • Audinate (Dante): Dante certification levels 1–3 include significant material on AES67 interoperability, as Dante devices can operate in AES67 mode. Level 3 certification requires lab exercises that configure mixed-vendor AES67 networks. Audinate’s training portal offers free and paid courses.
  • Lawo Academy: Lawo’s A__UHD core and mixing consoles rely on Ravenna, which is fully AES67-compliant. Their training programme covers RAVENNA/AES67 setup, PTP configuration, and redundant networking. Hands-on workshops are available at Lawo headquarters and regional events.
  • Yamaha Pro Audio: Yamaha’s training for the Rivage PM and CL/QL series includes AES67 configuration for integration with third-party Dante, RAVENNA, or ST2110 systems. They provide online modules and certified instructor-led classes.

Manufacturer-specific training is valuable when you are already working with a particular ecosystem, but it may not cover the broad interoperability challenges that arise in multi-vendor environments.

Media Networking Alliance (MNA) Resources

The Media Networking Alliance, which oversees the RAVENNA standard, offers technical white papers, webinars, and a certification for RAVENNA devices. While not a direct engineer certification, the MNA’s compliance and interoperability testing knowledge helps engineers understand validation procedures. Their public documentation is free and serves as excellent supplementary material.

Certification Options

Certification programmes validate the knowledge gained through training. Some are offered by professional societies, others by manufacturers. Choosing the right certification depends on your career trajectory and the recognition it carries in your target market.

AES Certified Audio Engineer

The Audio Engineering Society’s flagship certification, the AES Certified Audio Engineer, covers a broad set of competencies including AES67, network design, system integration, and measurement techniques. The exam is rigorous, typically requiring several months of study beyond the AES Academy courses. Candidates must pass both a written test and a practical lab component. This certification is vendor-agnostic and recognised globally. It is particularly valuable for consultants, system designers, and lead engineers who need to demonstrate comprehensive knowledge.

Manufacturer Certifications

Manufacturer certifications are often required for authorised support and integration work. Examples include:

  • Dante Certification Levels 1–3: Level 3 delves into advanced troubleshooting, AES67 mode configuration, and large-scale network design. Many AV and broadcast employers view Dante Level 3 as a strong indicator of AoIP skills.
  • Lawo RAVENNA/AES67 Certification: Lawo offers a certification for engineers who complete their RAVENNA training, focusing on clocking, stream management, and redundancy.
  • Yamaha Pro Audio Certification: This programme covers system design, network setup, and integration with AES67 peripherals.

Manufacturer certifications are most relevant if you work primarily within that brand’s ecosystem. However, because AES67 is the common denominator, these programmes still build transferable knowledge about PTP, QoS, and multicast management.

Vendor-Agnostic Certifications

Beyond the AES, AVIXA’s CTS certification includes a module on “Networked AV Systems,” which covers AES67, Dante, and other AoIP protocols. The CTS is widely recognised in the commercial AV installation market. For engineers who also work with broadcast standards, the SMPTE (Society of Motion Picture and Television Engineers) offers courses on ST 2110, which builds on AES67 for video transport. While not directly an AES67 certification, ST 2110 knowledge is increasingly valuable as broadcast facilities transition to IP-based production.

Choosing the Right Programme

The ideal training and certification path depends on several factors. Engineers should consider the following criteria:

Current Skill Level

Beginners should start with foundation courses from AVIXA or the AES Academy that cover IP networking concepts. If you already hold a networking certification like CompTIA Network+ or CCNA, you can skip basic TCP/IP modules and focus on specific AoIP topics such as PTP (IEEE 1588) and RTP payload types.

Work Environment Equipment

If your facility is predominantly Dante-based, pursuing Dante Certification Level 3 will provide the most practical benefits. Conversely, if you work with a RAVENNA system (e.g., Lawo or Merging), the Lawo Academy or MNA resources are more applicable. In mixed environments, the AES Certified Audio Engineer credential ensures you understand all standards.

Career Goals

For system designers and consultants, vendor-agnostic certifications (AES, CTS) carry more weight because they demonstrate impartial expertise. For staff integrators or support engineers, manufacturer certifications are often mandatory per partnership agreements. If you aim to work in broadcast, consider complementing AES67 training with SMPTE ST 2110 coursework, as many major broadcasters now require it.

Cost and Time Commitment

AES Academy online courses typically cost a few hundred dollars, while the AES Certified Audio Engineer exam fee is higher (around $500–$800). Manufacturer certifications range from free (Dante Level 1) to over $1,000 for advanced on-site training. In-person workshops add travel expenses. Engineers on a budget can start with free resources like Audinate’s free online modules and the AES67 specification document itself (available via the AES Standards page).

Format Preference

Self-paced online courses suit those with irregular schedules. Hands-on labs are critical for tactile learners. Many providers now offer virtual labs using simulation tools, but nothing replaces configuring a real switch and debugging PTP offsets with a live audio stream. If possible, choose a programme that includes a remote or on-site lab component.

Practical Steps to Get Started

Here is a suggested learning path for engineers new to AES67:

  1. Build networking fundamentals: Understand VLANs, IGMP snooping, QoS (DSCP), and IP addressing. Many AoIP problems stem from basic networking errors.
  2. Study the AES67 specification: Read the AES67-2018 standard to understand mandatory features (e.g., 48 kHz sample rate, 1 ms packet time, PTPv2 for sync). Pay close attention to the requirements for stream advertisement (RTSP/SDP) and clock redundancy.
  3. Complete an online training course: Enrol in the AES Academy’s AES67 course or AVIXA’s AoIP module. Take notes and review lab exercises.
  4. Set up a test network: Use two AES67-compatible devices (e.g., Dante via AES67 mode, or a RAVENNA interface) and a managed switch. Configure PTP, multicast groups, and verify with an analysis tool.
  5. Practice troubleshooting: Inject common faults – wrong PTP domain, mismatched QoS settings, or overloaded switch – and use Wireshark to diagnose them. This hands-on experience is invaluable.
  6. Pursue certification: Choose an exam that aligns with your career path. Prepare using the provider’s study guides and sample tests. Schedule the exam once you are consistently passing practice exams.
  7. Stay current: AES67 continues to evolve (e.g., enhanced redundancy profiles). Join the AES Technical Committee on Networking, subscribe to the MNA mailing list, and attend industry conferences.

Conclusion

AES67 is the bedrock of modern audio-over-IP interoperability. As more manufacturers adopt the standard and as networks grow in size and complexity, the demand for certified engineers will only increase. Investing in formal training and certification pays dividends in reliability, confidence, and career flexibility. Whether you choose a vendor-specific path or a broad, society-backed certification, the key is to commit to structured learning. Begin with the fundamentals, validate your skills through a recognised programme, and continue building expertise as the standard matures. Your ability to design, deploy, and troubleshoot AES67 networks will set you apart in the audio engineering profession.
