Audio Software


The main purpose of the DSP program is to capture signals arriving at the computer’s audio card input, processing them using special algorithms and mathematical models, and output. The application is based on an intuitive visual programming that allows you to create schemes of varying degrees of complexity without knowing any languages ​​by interacting with visual components. The graphics core of this software is made on OpenGL.

ARTA Software

The program has been recognized for its convenience and ease of operation, the possibility of a comprehensive analysis of measurement data. The ARTA Software program adjusts the following values: voltage at the amplifier output, number of fragments per test signal period, sampling frequency, type of periodic noise signal, test signal level, cut-off frequency, measuring channel, number of measurements for the averaging method of the impulse response and much more.

Room EQ Wizard

Determining the dependence of sound systems on the characteristics of the premises is one of the most important elements in the process of achieving high-quality sound. It is possible to get rid of room resonances only by “crushing” them with the help of a frequency response regulator or panel acoustic absorbers. However, in order to identify problems that arise when playing audio in acoustically unprepared rooms, you need to use specialized programs like Room EQ Wizard (abbreviated REW) with a measuring microphone and a preamplifier.


The real-time TrueRTA audio spectrum analyzer is excellent for tuning the amplitude-frequency characteristics of speakers in various rooms and halls. The software includes a whole set of tools, in particular, a real-time spectral analyzer (Real Time Analyzer), a dual oscilloscope, a signal generator, a digital level meter and a signal amplitude factor or a cross-factor. The application interface is extremely simple and convenient, all settings can be deployed as panels on the main working window.


WinISD is a small, simple and convenient program for modeling closed and phase inverter speaker systems, as well as six different types of active and a whole range of two-way passive filters of the first and second orders. Work in the program begins with determining the initial data of the speakers used: either by loading their parameters from the database, or by self-entering values. This software includes reference data on a huge number of electrodynamic heads, taking into account all possible characteristics (geometrical dimensions, Till Small values, electromechanical parameters, etc.).
