Multi-channel Audio Spectrum Analyzer is a set of Real-Time Multi-Channel Gauges for investigation of data accepted from any ADC you will want or 16-, 24- and 32-bit ADC of sound card. WDM drivers support. FFT Spectrum Analysis, OscilloScope, Frequency counter, AC/DC voltmeter, Signal-to-Noise Ratio, Signal-to-Noise and Distortion, Spurious-Free Dynamic Range, Effective Number Of Bits, Total Harmonic Distortion, Inter-Modulation Distortion, Phase Shift. Special modes of dual-channel FFT spectral analysis: Separate channels spectra, Spectra of digital sum, difference, product of two signals, Spectrum of digital product of original signal and its fundamental, Spectrum of Real and Complex Transfer Function, Cross Spectrum. Standart weighing of spectra according IEC and CCIR. Oscilloscope modes (for dual-channel ADC) are: original signals, sum, difference, dependence of one channel on another, amplitude distribution of input signals.

Universal oscilloscope GUI ( Real-time plot ) DLL library for data acquisition, simulation, debugging.
Advantages:
1.Speedy performance: the library makes it possible to bring out into the beams of the viewing oscilloscope over a million quantization steps of signal per second (on the Pentium III machine) – thus less than one micro-second is enough for one discreet. This software can be used for linking to real-time controlling programs as longer delays in relay of data to the oscilloscope don’t occur. The relayed data is instantly displayed in beams, the process of their relay and display is deterministic. It works regardless of the signal relay speed.
2. Versatility. Convenient integration with any applied software: viewing oscilloscope is executed as a DLL exporting only 9 functions, of which 4 are usually enough to work with.
3. A good graphic interface: an instance of a viewing oscilloscope created by this library looks like a separate window, entirely independent of the program which activated it. This window contains all elements typical for a control panel of a real oscilloscope.
4. Convenient data export-import: data already realised in the oscilloscope beams can easily be transferred to other programs via clipboard (copy - paste) in textual form or via the saved text file. In such form data can be easily imported into most electronic table kinds of programs, as well as into programs of the Matlab type. The oscilloscope also allows to quickly load such data file into its beams.
5. Reliable and robust: this library employs only the most basic Windows API functions and reliably works in all versions of 32-bit Windows starting from the first 95 version. We tested and practically confirmed the possibility of relay of data to this oscilloscope directly from the computer’s hardware interrupt procedure (IRQ) and from any kind of anisochronous thread - which is important.
