CatMV by GistaT Group

The CatMV program is a realization of the "Caterpillar"-SSA method for analysis of time series, which may contain missing values. The implemented algorithms result in extraction of additive components of time series such as trends and periodic components, with simultaneous filling in the missing data (if any). The program is able to perform forecasting if to add missing values after the last point of the time series.

OscilloMeter - Spectrum Analyzer by Oleg Ya. Shmelyoff

The OscilloScope + FFT Spectrum Analyzer for real-time investigation of data accepted from sound card or other ADC you will want. Maximum number of channels, sampling frequency, bit rate of data are limited only by type of used ADC. FFT results analysis is realized in real-time mode. Fully functional demo works with ADC of sound card.

Transcribe! for Windows by Seventh String Software

Transcribe! is an assistant for working out a piece of music from a recording. Transcribe! offers many features aimed at making the transcription job smoother and easier, including the ability to slow down the music without changing its pitch, and to analyse chords and show you what notes are present.

CaterpillarSSA by GistaT Group

The program is based on the powerful model-free method of time series analysis Caterpillar-SSA (Singular Spectrum Analysis). The result of the Caterpillar-SSA processing is identification, analysis and forecast of additive components of time series (trends, periodicities, noise). The program can be applied to multivariate analysis/forecasting and change-point detection.
