Aarhus Soundsystem uses SAFE to improve measurement quality

Aarhus Soundsystem is using the SAFE measuring and analytics software platform to gain insight into their loudspeakers performance

Aarhus Soundsystem is a tech start-up aiming to develop a sustainable speaker with as good Hi-Fi as possible.

To attain this goal, Aarhus Soundsystem needs precise and valid measurements to analyze their loudspeakers frequency response compared to their simulations. Troels Mikkelsen is the COO at Aarhus Soundsystem and Encida is proud to support his quest for building the best sustainable loudspeaker possible.

Aarhus Soundsystems challenge

Aarhus Soundsystem uses a lot of simulations, subjective listening tests and measurements to design and evaluate their loudspeakers performance. However, they have had bad experiences with measurements having difficulty getting accurate results. They wanted to ensure they got valid results to continue the development with a strong foundation in objective measurements.

Testing using SAFE

Troels has designed loudspeakers for many years and says, “SAFE has greatly improved the experience of collecting measurement data in comparison to other programs”.

Using the SAFE platform to do audio tests, lets Troels easily build the measurement sequence, by dragging and dropping, enabling him to test the loudspeaker in several different angles. He can then process the data using different processing blocks. “The different options you have in processing means you can get a lot of different views of the data, all in one program”, Troels says.

Achievements

In the end “we got some valid test results from 0 degrees to 90 degrees off-axis in the frequency range of 100 Hz – 20000 Hz”, Troels says. This will be used to further improve their crossover-filter and a better sounding loudspeaker.

Processing data in SAFE

SAFE is Encidas platform that lets you test audio and electronic devices easy and fast, helping you build high quality tests. With SAFE you don’t waste development time interfacing with equipment, writing code or writing documentation. SAFE helps you build your audio and electronic test by handling test sequencing, storing important data and documentation while you simply drag and drop. SAFE can interface to other programs and languages such as Matlab, Python and LabView making your tests as customisable as possible. 

Tests in SAFE is 100% reproducable, meaning data and test information will not get lost by your team. You will always know exactly what equipment and processing were used to get your results. Entire test cases can also be shared within teams, increasing the transparency and productivity.
