Wohler outlines the technical requirements for confidence monitoring in immersive audio workflows, emphasizing the need to validate metadata and rendering behavior alongside signal integrity. The company highlights its iVAM2-CMD and MAVRIC solutions as tools for end-to-end monitoring of object-based audio formats like Dolby Atmos and MPEG-H.
The shift from channel-based to object-based audio means signal presence no longer guarantees a correct listener experience. If metadata describing object position or movement is corrupted during transcoding or transmission, the immersive sound field fails even if the audio remains intact. This technical shift forces broadcasters to move beyond simple signal checks toward comprehensive rendering validation. As live sports increasingly adopt Dolby Atmos and MPEG-H to drive engagement, the industry must standardize how it monitors the relationship between audio objects and metadata at the consumer endpoint. Watch for increased adoption of HDMI-based monitoring tools as engineers seek to verify the final rendered output reaching the viewer.
Wohler has deepened its collaboration with Fraunhofer IIS to bring MPEG-H Audio rendering directly into its flagship iAM-12G-SDI monitor. The iAM-12G-SDI now supports MPEG-H rendering with a browser-based interface that lets operators switch audio presentations, select commentary, and enable dialog enhancement before the encoding stage. The unit renders to immersive loudspeaker configurations of up to 9.1+4 channels as well as downmixes to 5.1 and stereo, and it also supports binaural rendering for headphone monitoring. Adrian Murtaza, Chief Business Development Manager at Fraunhofer IIS, described the capability as an additional layer of quality control for immersive and personalized audio production. On the business side, Wohler has expanded its product line to cover both facility and consumer-endpoint monitoring. The iVAM2-CMD complements 12G-SDI and AoIP options with HDMI inputs, including consumer media devices such as set-top boxes and streaming players, allowing operators to monitor Dolby Digital, DD+, E, and Atmos the same way a home viewer receives them. The company also introduced a new ATOMS token-based model for MAVRIC, its cloud-based remote monitoring platform, which won Best of Show at IBC 2024 and provides remote monitoring, automated alerting, and integrated conferencing through a web browser interface. MAVRIC itself represents Wohler's push into cloud-based monitoring-by-exception workflows. Wohler launched MAVRIC as a multichannel audio and video remote indication and control system that streams encoded audio and video from in-rack probes into a cloud application, enabling operators to view live video and listen to audio from anywhere. The system supports configurable alerts for predetermined error conditions and includes a mobile app with built-in conferencing for real-time problem resolution. Wohler also announced the iVAM2-MPEG hardware monitor at IBC 2025, adding MPEG SRT, H.264, and HEVC monitoring with AAC, Dolby Digital+, and MP3 audio support to complement its baseband and IP product lines.
Wohler has introduced advanced monitoring tools, including the iVAM2-CMD and MAVRIC, to support Dolby Atmos and MPEG-H workflows. These solutions prioritize metadata validation and object-based rendering, ensuring signal integrity for broadcasters. This shift is critical because corrupted metadata can ruin immersive sound experiences, even if the audio signal remains intact.
In object-based audio, signal presence does not guarantee a correct listener experience. If metadata describing object position or movement is corrupted during transmission, the immersive sound field fails, making comprehensive rendering validation essential for broadcasters.
The iVAM2-CMD hardware enables last-mile monitoring by analyzing HDMI outputs from consumer devices like set-top boxes and streaming dongles, allowing operators to monitor Dolby Atmos and other formats exactly as a home viewer receives them.
MAVRIC is a cloud-based remote monitoring system that provides end-to-end visibility across signal distribution chains. It features automated alerting, integrated conferencing, and a new ATOMS token-based model for remote monitoring-by-exception workflows.
The iAM-12G-SDI monitor includes MPEG-H rendering capabilities with a browser-based interface. It allows operators to switch audio presentations, select commentary, enable dialog enhancement, and render to configurations up to 9.1+4 channels or binaural headphone outputs.
