Immersive Measuring
The analysis of surround and immersive audio requires tools that not only measure but also visualize spatial relationships in a way that reflects what we actually hear.
RTW’s suite of immersive metering instruments brings this capability to life, giving sound engineers immediate insight into the spatial balance, phase relationships, and overall integrity of their mixes.
Immersive Sound Analyzer
The Immersive Sound Analyzer visualizes the relationships between channels within up to two layers. It supports channel formats for both surround (e.g., 5.1) and immersive audio, such as Atmos 7.1.4.
Its graphical display is designed so that the dynamic behavior of all elements corresponds to the subjective listening impression, allowing the balance of a surround or immersive program to be monitored intuitively at a glance.
The Dominance Indicator (white cross) further shows the position of the subjectively perceived acoustic focal point.
With the Immersive Sound Analyzer you can:
- Monitor the overall spatial balance of the surround- or immersive image
- Measure total loudness within layers
- Monitor the relationship between the layers
- Identify phase issues to ensure correct downmixing
- Evaluate stereo width and perceived position between channel pairs
- Detect correlation problems in the LFE channel
Matrix Correlator
The Matrix Correlator displays phase relationships between all channels, supporting formats from stereo up to 22.2.
It provides a complete overview of inter-channel correlations, making it easy to detect potential phase issues within a mix.
Multi Correlator
The Multi Correlator is a valuable tool for working with surround or immersive sound, ensuring that a surround mix will also translate correctly when downmixed to stereo or even mono.
It provides a clear, single-view display of the phase relationships between all channels.
Polarscope
Inspired by the classic vectorscope, the Polarscope introduces a new algorithm that visualizes inter-channel correlations using a spatially aware coordinate system. Each loudspeaker position is represented as a vector in space, and signal levels are combined to generate real-time geometric shapes on the display.
In a traditional stereo vectorscope, identical channel content appears as a vertical line, while polarity inversion creates a horizontal line. The Polarscope extends this principle to surround and immersive layouts, where signal interactions form unique geometric patterns that reveal spatial attributes such as:
- Dynamic Development of Spatiality (Image width and depth)
- Front/rear energy balance
- Channel delay mismatches
- Phase issues or mirror symmetry
The Polarscope algorithm was presented by our software developer Pavel Smokotnin at the 158th AES Convention (2025 Warshaw).

Speech Intelligibility Meter
AI-driven, objective measurement of dialogue clarity
The Speech Intelligibility (SI) Meter for TMxCore is designed to help broadcasters and professional audio engineers tackle one of the most critical challenges in production: keeping dialogue clear and intelligible.
Developed in close cooperation with Fraunhofer IDMT, the SI Meter uses advanced AI-based algorithms to provide an objective, real-time measurement of how well speech can be understood in a mix. Instead of relying on subjective impressions, engineers get clear visual feedback that guides them in balancing dialogue, effects, music, and background sounds.
This collaboration builds on more than nine years of joint research, beginning with the SI4B (Speech Intelligibility for Broadcasting) project, and has since evolved into a robust solution now available within RTW’s TMxCore platform.
Why it matters
Whether it’s:
- Unclear dialogue in a drama series
- Background music masking voices in reality TV
- Crowd noise overwhelming commentators in live sports
- Dialogue clarity issues in streaming and on-demand content
… the SI Meter gives engineers the tools to deliver consistent speech clarity across all formats.
Key benefits
- Objective results – AI-powered analysis replaces guesswork
- Real-time feedback – instantly see how dialogue is perceived
- Easy-to-use interface – intuitive visual display within TMxCore
- Broad applications – ideal for broadcast, post-production, streaming, and live events
- Developed in close cooperation with Fraunhofer IDMT
Built for TMxCore
The Speech Intelligibility Meter is available as a license option for TMxCore, RTW’s next-generation metering platform built on the legacy of the classic TouchMonitor series.
Loudness Tools for Full Compliance
For many years, RTW has taken part of forming the international loudness standards in ITU and EBU. Loudness is key to us, so in TMxCore we have implemented the full loudness engine known from our high end broadcast meters.
TMxCore supports all international loudness standards such as EBU R128, ITU-R BS.1770-4/1771-1, ATSC A/85, ARIB, OP-59, AGCOM, CALM, LEQ(M), TASA and SAWA.
On top of the ITU/EBU loudness standards, you’ll find support for Dialog Gated Loudness Measurement, enabling compliance with dialog-based specifications, which are aligned with Netflix delivery standards.
Chart
The Chart provides a clear visual timeline of loudness and speech intelligibility, making it easy to monitor dynamics and consistency in broadcast, streaming, or post-production.
It can display Momentary, Short-Term, Integrated, and True-Peak Loudness, as well as Speech Intelligibility over time, giving insight into both transient details and long-term trends.
With a flexible time range from 10 seconds to 2 hours, auto-scaling, and customizable appearance, the Chart adapts to any workflow. It can also synchronize with other meters for a complete overview.
Summation
The Summation instrument provides a bargraph display of summed loudness values — M, S, and/or I.
It can also present dialog-gated measurements: Momentary Dialog-gated (MD), Short-term Dialog-gated (SD), and Integrated Dialog-gated (ID).
Numerical
The Numerical instrument provides a readout of selected loudness and dialogue measurement parameters in a numerical display. A large range of parameters can be displayed, although it is not expected that all parameters will be used simultaneously.
LRA (Loudness Range)
The LRA (Loudness Range) instrument displays a graphical representation of the loudness variances within short time periods.
These are measured against the Loudness Range (LRA) descriptor specified in EBU R 128.
It is used to show whether a program has a continuously constant loudness or a high variation between low and high level components.
It allows for making assumptions on whether the program has seen or requires dynamic processing with regard to the intended distribution path.
Dialog Gated Loudness Measurement
The RTW metering engine supports dialog-gated measurements, ensuring compliance with dialog-based specifications that for example adhere to Netflix delivery standards.
The Numerical instrument provides metrics such as ID (Dialog-Based Integrated), SD (Dialog-Based Short-Time), and D (Dialog Content Percentage).
The LRA instrument displays the Dialog-Gated Loudness Range, while the Dialog Detector identifies when dialog is present. This detector can be resized, ranging from a small overlay to covering the entire screen.
Users can specify which channels contain dialog, typically assigning it to the Left, Center, and Right channels.
LFE Bleed
It is essential to ensure that no high-frequency content is present in the LFE channel, as this can cause severe playback issues with certain encoders, including binaural formats.
As a general recommendation, the LFE frequency range should be limited to avoid problem during distribution.
The LFE Bleed Instrument measures energy above a certain frequency (120 Hz by default) and displays a momentary loudness value on a dBFS scale in a compact bargraph. The bar appears in red by default, indicating that the expected state is absolute silence. Any visible activity signifies unwanted content leaking into the LFE channel.
Ratio Instrument
The Ratio Instrument displays the difference, or ratio, between two loudness measurements.
It is particularly useful for monitoring ratios within one audio source:
- Loudness-to-Dialog Ratio (LDR)
- Background-to-Dialog Ratio (BDR)
Or between two different sources:
- Compare loudness before and after processing
- Compare loudness of different rendered layouts (immersive vs stereo, mono downmix etc.)
All in all, the Ratio Instrument offers a flexible way to evaluate balance, consistency, and the impact of processing across a wide range of production scenarios.
Stereo, Surround, Immersive
With support for up to 32 audio channels, TMxCore can handle channel configurations from stereo to 22.2.
Among the many supported formats you will find 5.1 and 7.1 surround as well as 7.1.4 and 9.1.6 immersive.
PPM
TMxCore features a fully equipped PPM meter, ensuring reliable measurement across any audio channel.
It supports a broad selection of scales, covering all requirements of a professional production environment - a crucial advantage since broadcasters often rely on very specific scale types.
A switchable peak-hold indicator, peak memory, and over indicator further enhance its functionality.
For stereo applications, a built-in correlation indicator between the bargraphs helps identify potential phase and correlation issues.
Moving Coil
The Moving Coil instrument is available in 2-channel stereo mode.
It provides several scales and setting options. The PPM (British) or VU displays can be shown as single or combined, vertical or horizontal instruments.
Loudness scales or a combined PPM and Loudness display (BBC mode) are also available.
Stereo Correlator
The Stereo Correlator visualizes the phase relationship between the two channels of a stereo signal, providing quick insight into stereo compatibility.
Essential in mixing, mastering, and broadcast, the Correlator helps engineers maintain consistent sound quality and ensure reliable mono compatibility.
Vectorscope
The 2-Channel Audio Vectorscope uses a Lissajous display to visualize the phase relationship between two stereo channels in real time. It quickly reveals stereo width, balance, and phase issues such as shifts, rotations, or cancellations.
Widely used in mixing, mastering, and broadcast, the Vectorscope is an essential tool for ensuring proper stereo imaging, phase alignment, and mono compatibility.

- Seamless Workflow Integration – connect directly to mixers, automation systems, and external devices to streamline production workflows.
- Actions are also available in all current buttons. So, when you hit MUTE, you can send an action at the same time.
With Action Instrument & OSC, TMxCore evolve from pure metering solutions into fully interactive, customizable control hubs.
Network Display: Metering Anywhere, Anytime
With Network Display, engineers, mixers, and operators can view real-time audio measurements anywhere on the local network using a standard web browser - without the need for extra hardware.
Whether monitoring from the control room, a production suite, or across multiple workstations, Network Display provides unmatched flexibility and helps streamline workflows.
You can expand the Network Display feature by adding additional screens through licenses. Each extra screen effectively acts as a new metering instance in your setup - delivered at just the cost of a license.
Delay Compensation
With the introduction of dialog-gated loudness measurement, some instruments may introduce significant delay - up to 2 seconds in certain cases. This is necessary, as the algorithm requires time to reliably detect whether the audio contains dialogue.
While such latency is not ideal, RTW’s metering engine includes built-in delay compensation, and in addition, all metering instruments provide audio outputs.
Delay compensation ensures that:
- All meters are aligned visually
- All audio outputs remain time-aligned, so playback corresponds precisely with the display.
