FFT Properties v5 - Spectrum analyzer

Dew Research develops FFT (Fast Fourier Transform) software for frequency analysis applications, a PC-based FFT analyzer program named FFT Properties.

FFT Properties is designed for spectral analysis of very long signals. It includes both optimized computational part and visualization engine required for this purpose. It builds upon version 3.5 and delivers among other features:

• Recording and playback with arbitrary sampling frequency by using the fastest sample rate converter.
• Real time envelope and energy computation during recording with history overview and frequency analysis.
• 24-bit/96kHz and 24-bit/192kHz recording and playback support.
• Support for Windows Audio Compression Manager allows reading any Windows-supported file format on the system.
• Support for text files, raw/pcm (arbitrary format) files and wav file format.
• Ability to compare multiple averaged spectrums.
• Excellent quality 3D Surface chart with unique navigation capability.
• Multithreaded batch file processing for rate conversion, digital filtering, signal generation, signal modulation, demodulation, envelope detection and signal conversion.
• State-of-the-art zoom-spectrum feature. Select higher resolution and narrower bands with any sampling frequency.
• Fastest arbitrary real number factor rate conversion with speeds and accuracy exceeding current alternatives.
• Special real time high speed narrow bandpass filter, can have any bandwidth limited only with the length of the signal.
• Basic digital filter designer support with a wide range of optimal FIR and IIR filtering.
• Math expression evaluator for scaling of signals.
• HP Calculator style signal generator.
• Save and load settings of all processing pipes and charts.
• All signal processing is streamable via audio processing pipes.
• Frequency analyzer features extremely accurate non-parametric phase angle measurement of non-periodic signals and linear phase peak filtering.
• Analytical spectrogram with highest accuracy imaging in an FFT analyzer with time-frequency analysis.
• Support for real time analysis of largest file sizes.
• Read/write and analyze complex/analytical signals.
• Runs with Windows Vista and XP 32 and 64bit.

The Spectrum Analyzer features many unique frequency analysis methods which can not be found in any other frequency analysis software.

FFT Properties v3.5 - Spectrum analyzer

The predecessor to v5 is ideal for studying fast Fourier transformation as well as for practical spectrum analysis, or to FFT Excel spreadsheet data. The FFT code is very fast and optimized for Pentium 4 CPU's.

FFT Properties is a report-oriented, real-time Scope/ Spectrum analyzer. It features:
- Parametric windows
- Peak interpolation
- A rich set of peak marking features
- Discrete Fourier Transform (DFT)
- On-line wavelets decomposition
- Higher order spectral analysis
- Cross- and auto-correlation
- Cepstral analysis
- Cross-spectral analysis
- FIR filter designer
- Decimation and interpolation
- Built-in signal generator
- Advanced printing
- High quality charts

In other words, with FFT Properties you can evaluate your sound card for frequency response and non-linearities, tune your guitar, whistle and look at the frequency, make your own car tire balancer, take a close look at your amplifier etc. For more information, examples and tutorials click here for full documentation about FFT Properties our frequency analyzer software.
