Base of test reports
In RAA lab we discover of new dependencies in audio as the result of monitoring and analysis of the data of the measurements. The results of the measurements are not to keep in secret, they are available in detailed test reports on the RAA website. Reports were optimized for ordinary persons without specific knowledge (non-professionals) who want to compare audio devices characteristics.
RAA constantly develop new types of graphs in such a way that it is possible to use information without additional complex calculations. For example, to compare the loudness of the amplifiers, the levels are represented not in volts (V), but immediately in decibels (dB). We place general explanations next to graphs.
We published test reports of two types. The first is the simple report for persons who are poorly versed in characteristics and specialized graphs. It is a product characteristics review with simple explanations. The second type is the professional report for persons who are interested in more detailed report.
On-line services on RAA website let you to do direct comparisons of audio devices
, to estimate coupling of parameters and match audio devices for best joint work
Development of the measurement stands and software
We are the developers of the software-hardware complex Reference Audio Analyzer. All measurements stands and equipment and unique software are our own production. All that allows simplifying the measurement process, to calculate various dependencies and prepare data for statistical processing. We implemented a number of new tests that did not exist before in the test systems of other manufacturers. So we were able to cover the spectrum of measured parameters more widely.
RAA laboratory and research
The main direction of our research is the interaction of the parameters of the headphones and amplifiers. Detailed measurements, the collection of statistical data, the creation of stands and software allow us to find new dependencies and develop algorithms for selecting the best match of headphones and sources. RAA can rightly be proud of the discovery and popularization of various dependencies
in the field of personal audio.
