MSU Noise Estimator 0.1 is an ideal tool for anyone who has to work with audio a great deal. It is actually a free MSU VQM plugin for noise level estimation. It includes implementation of three most popular algorithms for measurement of noise level. By results of job of the metrics the plot of frame-accurate value of noise level is constructed. Final value of the metrics is average arithmetic of all frame-accurate values.
Algorithms:
- MAD - For each frame do HAAR wavelet decomposition. Than evaluate median of HH-component's absolute values. Final value of the metrics is the normalized median.
- Block-Based - Frames are tessellated into a number of 8x8 blocks. Standard deviations of intensity (measures of intensity variation) are computed for all the blocks and sorted. The block with the smallest standard deviation has the least change of intensity. The smaller the standard deviation, the smother the block. The intensity variation of a smooth block may be due to noise, in which the standard deviation of the block is close to that of the Gaussian noise added. Normalized average arithmetic values of 30 % of all blocks with the least values grows is the final value of the metric.
- Spatio-Temporal Gradients - For each frame is doing wavelet decomposition. computing temporal and spatial histograms. The initial estimation of noise level is defined by value at which temporal or spatial histogram achieves the maximal value. The decision of whether to use the spatial or temporal histogram is based on the deviation of the histogram from the Rayleigh distribution. Then this estimation is corrected, using Kolmogorov-Smirnoff test. The normalized corrected estimation is the final value of the metric.
Major Features:
- Completely free!
- Offers three most popular algorithms for measurement of noise level
- MAD
- Block-Based
- Spatio-Temporal Gradients
- Very easy to use

It contains basic statistical functions, such as Students t-test and linear correlation of two sets of data (two columns in a spreadsheet). XL-Plot has a number of build-in functions that can be fitted to the data in columns on a spreadsheet or to a curve in a graph. The user can easily add fitting functions of his own design.
Additional options are Fourier transformation, (de-)convolution, eigen decomposition and matrix inversion.
Features.
Simple, intuitive "visual" program layout.
Fast: No useless options, few dialogue windows, lots of short-cuts and hence a minimum of mouseclicking to do, resulting in a gain of time.
The program is build around two types of window each having its own menu:
1) Windows showing vector drawings (drawing sheets).
2) Windows showing columns of numerical data (spreadsheets).
Items in the last two types of window may communicate such that a modification in a column in a spreadsheet results in a change in the associated vector graph, allowing easy editing.
By using copy and paste functions from the menu, data from either window may be copied to a spreadsheet or to a drawing sheet resulting in a column of numbers or a graph respectively.
The math library contains many useful functions such as convolution and deconvolution, Fourier transform, matrix inversion and eigen decomposition of a matrix.
Statistical tests for data in spreadsheet columns: linear correlation, chi-2 test, Students t-test, Fishers F-test, Tukeys q-test (one-way anova).
Bitmaps may be imported and manipulated on the drawing sheet.
Graphics may be exported to other vector drawing programs.<<less
UnicodeDataBrowser 1.2
UnicodeDataBrowser is a browser for the UnicodeData.txt file. more>> UnicodeDataBrowser is a browser for the UnicodeData.txt file, which contains much useful information but is not easily read by humans. The browser creates a scrollable table in which columns represent properties. The table may be sorted on any column. Abbreviations are expanded and characters cross-referenced in decomposition and casing fields are named. Regular expression search restricted to a selected column is available. The set of characters for which information is displayed may be restricted to those characters matching a regular expression on a specified property. Each such filtering operation applies to the output of the previous filtering operation unless the table is reset to the original full set of characters, so filtering on multiple properties is possible. If an up-to-date local copy of UnicodeData.txt is not available, it can be downloaded automatically from Unicode.org.<<less

DivX Free Codec 1 is an amazing application for you! It includes DirectVobSub (vsfilter), AC3Filter, and FFDSHOW.
- DirectVobSub (vsfilter)
-
- DirectVobSub is a tool for displaying subtitles. Your subtitle file should have the same filename as your video file (for example Movie.avi and Movie.sub) and should be in the same folder as your video file. Then the subtitles will automatically be displayed in most players.
- DirectVobSub is simply a DirectShow filter which can be used to display subtitle. It integrates automatically with any DirectShow player like the Windows Media Player, Media Player Classic, The Core Media Player and others.
- AC3Filter

- It has a priority on wide functionality and convenient settings. Filter can decode following audio formats: AC3/DTS/MPEG Audio. It also supports multi-channel and digital (SPDIF) outputs.
- FFDSHOW
-
- FFDSHOW is a DirectShow decoding filter for decompressing DivX, XviD, H.264, FLV1, WMV, MPEG-1 and MPEG-2, MPEG-4 movies. It uses libavcodec from ffmpeg project for video decompression, postprocessing code from mplayer to enhance visual quality of low bitrate movies, and is based on original DirectShow filter from XviD, which is GPL'ed educational implementation of MPEG4 encoder.
- First of all, the FFDSHOW consumes way less CPU power than original DivX codecs, even with maximum post-processing. At the same time the post-processing seems to give excellent quality results and allows more configuring than the original DivX 5 codec. It can even automatically reduce post-processing if your CPU is getting overloaded. The noise filter adds a kind of a rasterising effect to the picture - might be useful in some cases. The alpha version also includes experimental playback for MPEG-1 and MPEG-2 files (such as VCD and SVCD movies), which works pretty damn well. Only problem is that MPEG-2 playback can't play the SVCD clips directly from the CD, but requires the video to be extracted to the HDD by using VCDGear first. It uses libavcodec from ffmpeg project for video decompression, postprocessing code from mplayer to enhance visual quality of low bitrate movies, and is based on original DirectShow filter from XviD, which is GPL'ed educational implementation of MPEG4 encoder.
