Consulting to manufacturers
Ever since i designed an automated platform (for DAS Audio) for
directivity measurements and processing in 1992, i have been involved in
custom array modelling. I have written numerous algorithms to perform all
sorts of calculations.
Also, i have given almost one hundred product presentations and seminars
around the world.
My services to loudspeaker manufacturers are as follows:
- Array plugins for modelling software
I have extensive experience with developing these. Over the last 3
years i have spent a lot of time researching the best approaches for
line array modelling.
I can develop array plugins for EaseFocus (generic line array aiming
software) as well as EASE.
Since some kind of aiming software is an absolute must for line array
systems, EaseFocus is a universal software that is used in combination
of acoustical modules created for every box model. Manufacturers such
as DAS (Spain), Turbosound (UK), QSC (USA), TOA (Japan), Peavey (USA) and Dynacord (Germany) are
part of the list of manufacturers using EaseFocus.

- Development of directivity measurement and post-processing platforms
Polar measurements are essential for correct system design as well as
for sound system modelling. I can design a high resolution measurement
system that includes all post-processing to achieve a powerful
system capable of very comprehensive reporting as well as conversion
to loudspeaker modelling formats (EASE and CLF, as well as older
formats if needed).
Numerical reporting includes:
- Beamwidth (-3, -6 and -10 dB, 1/3rd oct., 1 oct, right, left,
up, down, horizontal, vertical)
- Q&Di (1/3rd oct., 1 oct)
Graphical reporting includes:
- Beamwidth (1/3rd oct., 1 oct., 1 oct, right, left, up, down,
horizontal, vertical)
- Q&Di (smoothed 24 point/oct, 1/3rd oct., 1 oct)
- Power (smoothed and unsmoothed 24 point/oct, 1/3rd oct., 1 oct)
- Relative frequency responses (smoothed, 1/3rd oct., right, left,
up, down)
- Absolute frequency responses (smoothed, 1/3rd oct., right, left,
up, down)
- Isobar and waterfall displays (horizontal, vertical)
- Polar plots (1/3 oct. and 1 oct.)
- Development of production QC systems
Loudspeaker boxes and components need to be measured during production
to ensure consistency and exclude defective units and thus avoid bad
sounding units to reach the customer. I can develop Quality Control
systems that take robust measurements within a noisy production
environment within a few seconds.
Checked parameters include:
- Frequency response
- Impedance
- Polarity
- Distortion / Rub&buzz
- Marketing
I can help with defining a product line and generating powerful
technical marketing materials. Specifically, due to my past experience,
i can particularly help with reaching the Spanish speaking worldwide
market.
