Modules

RTA, room analysis, sound level logger, signal generator

Precise & cost-effective

Measurements using standard sound cards and measurement microphones.

Module RTA

Real-Time Analyzer for acoustic measurements

Evaluation of car, hi-fi, PA and home cinema sound systems or
Measurement of noise emissions from machinery or equipment or
Display spectrum / sound level at live events or
Check of soundproofing measures

Optimize Car Hifi via Sound Profiles

Car audio systems should not be tuned linearly due to the vehicle’s interior layout and materials. But what does proper tuning look like? This is where our ready-made and free sound profiles for cars, SUVs... come in handy.

You can find the profiles, as well as the free of charge Profile Editor, in the Downloads section.

Difference measurement

Difference measurement is a particularly effective tool for making comparisons. It is derived from two RTA channels and displayed in a separate channel.

Module acoustic room analysis

Why room acoustics is so important?
Room acoustics determine whether speech is clearly intelligible, music is captivating, or a room feels straining. Yet every room has different requirements: a control room requires maximum precision, a conference room perfect speech intelligibility, and a concert hall the right balance of clarity and richness.

What do all these readings mean?

The software analyses all parameters and evaluates them according to the selected room type. This allows you to see at a glance whether your room is optimally tuned:

How well do the measured room parameters (RT60, EDT, etc.) match my room type, e.g. ‘Home Cinema’? Result as a pass/fail assessment
What do the measured values for RT60, EDT, C50, etc. mean? Reverberant or dry?
How good is the acoustic homogeneity of the room?

Optimised workflow

To obtain meaningful results, it is recommended to take the average of several measurement points. This is particularly easy with x1RTA:

x1RTA supports direct selection from up to 10 microphones (= positions).
The ‘Measurements’ page collates all measurements for the positions, including a description.
You can calculate average values from any set of measurements.

x1RTA makes room acoustics measurable – and instantly assessable.

Comparison of measurement series

The ‘Comparison’ page allows you to compare measurement charts of any set from identical and different parameters. It is therefore ideal for comparing acoustic measures within a room.

Reports

Create informative reports based on templates for individual measurements. Supplement the measurements with information such as the measures taken for acoustic optimisation, an interpretation of the measurement values, or a description of the measurement setup.

The measurement conditions can also be specified here (room dimensions, temperature, etc.).

In a professional context, your company logo can be added to the report.

Module highlights

Standard and Extended measurement range up to 50 Hz – 10 kHz with 1/3 Octave
Support for up to 10 microphones: position the microphones in the room and carry out the measurement step by step without repositioning or reconnecting them
Efficient workflow for averaging and labelling measurement series
Use ready to use report templates to present results professionally to your clients, including your company logo
Tips for best results: Position the loudspeaker and microphone
Save measurement series

Module Sound Level Logger

The Logger module allows you to record sound levels (SPL in dB, Peak dB, Leq, running Leq and Lex,8h) in rooms, at workstations or for machinery over time. Optionally, the measured values can be weighted according to the A or C scale.

SPL calibration

You can easily calibrate the microphone and audio interface using a microphone sound level calibrator.

Module Signal Generator

The built-in signal generator provides the signals required for both internal and external measurement modes. This means you can use the RTA module and the pink noise signal to generate meaningful frequency responses – in real time!
