Real time spectrum analyzer with multi-channel support. The application offers extensive capabilities for analysis of real world signals. It features parametric windows, peak interpolation, rich set of peak marking features, cepstral analysis, cross spectral analysis, averaging, periodogram, surface spectrogram, 24-bit/96kHz and 24-bit/192kHz recording and playback support and a large set of printing options. Multithreaded file processing allows conversion of text files to/from binary and wav formats, digital filtering, rate conversion, envelope detection, signal modulation and demodulation, scaling, channel multiplexing and demultiplexing. Ability to process and analyze analyitical (complex) signals. The application also offers an easy and quick way to learn about the properties of FFT and to gain the fundamental insight in to digital signal processing and analysis.
