ArtemiS
Sound and Vibration Analysis:
Intuitive – Efficient – Reliable
ArtemiS
Recording • Analysis • Playback
ArtemiS is a multi-functional software application, designed to enhance productivity in all areas of
sound and vibration analysis. As a complete solution, ArtemiS provides you with tools for multi-
channel recordings, extensive analyses and aurally accurate playback.
Your Advantages
• Simultaneous listening, analyzing
and interactive filtering
Only with your own ears, can sound problems be
identified effectively
• Intuitive handling
Start measuring and analyzing right away – no
lengthy learning curve
• Flexibility
Quickly customize configurations for filters, analyses, statistic evaluations,
diagrams and data exports to fit your needs
• Enhanced and accelerated testing procedures
Future-proof options in ArtemiS save you time and work
Benefit from these advantages in many areas:
Signal and vibration analysis in both time and frequency domain, system analysis, multi-
channel data acquisition, troubleshooting, sound engineering, sound quality

With its straightforward layout, the ArtemiS user interface can be used intuitively: Configuring
analyses and diagrams, selecting filters or starting a data export – everything is done with just a
few mouse clicks. The screenshot above shows a layout example, which can be modified to fit
your requirements.

The ArtemiS project displays everything you need in five clearly arranged Pools:
Your material (time-domain signals), your tools (e.g. filters, analyses and statistic evaluations)
and your destination (e.g. a diagram or a file export). The functions inserted into any pool can
be enabled / disabled for the current calculation via the checkboxes.

The scope of analysis possibilities in ArtemiS ranges from common standardized methods,
such as level calculation and octave analysis, to the calculation of transfer functions and the
determination of psychoacoustic parameters and even includes unique analysis methods,
such as the “Relative Approach” and analyses based on a hearing model.
The ArtemiS Tool Packs
Brick by Brick to Your Personal ArtemiS
Available ATPs:
• Module for playback of any time-
domain sequence
• Various modules with special
analysis functions, e.g. psycho-
acoustic parameters, analyses as
functions of any reference quantity,
system analyses and others
• Module for extended 3D-display of
diagrams
• Module for extending the filter
functions
• etc.
You can extend your ArtemiS Basic Version with a wide range of additional modules. This
modular design of the software allows you to choose the most efficient and affordable solution
and to perfectly adapt ArtemiS to your needs.
The ArtemiS Mark Analyzer
What You See is What You Hear!
The Mark Analyzer allows a time-domain signal to be analyzed in detail with your eyes and ears
simultaneously. The playback cursor shows the current playback position in the analysis diagram.
And with the playback dialog, you can play the desired channels at their original speed, faster,
slower or with different volumes. Even structure-borne sound can be played back!
(Playback requires ATP 01 in addition to the ArtemiS Basic Version.)
The Interactive Filters
In the Mark Analyzer, a file can be filtered interactively, i.e. the effect of the filters can be seen
and heard immediately. That way, you can find out which characteristics dominate the sound
impression, and predict which modifications could lead to a better sound.
(Playback requires ATP 01 in addition to the ArtemiS Basic Version.)
Data Management with ArtemiS
Documentation with Flexible and Quick Data Access
ArtemiS comes with the HEAD Data Portal, which allows you to document, organize, display,
compare and play back your data. Making recordings costs time and money. Protect this
investment by means of the comprehensive documentation and quick access provided by
HEAD Data Portal.
