Free to calibrate software for windows

Quickly setup your display settings using the Display Calibrator Opera widget The Display Calibrator widget for Opera browser allows you to setup your display.
It calibrates brightness, colors, contrast, focus, gamma, geometry, legibility, resolution, response time and subpixel rendering of your display.
System requirements:
- Opera 9 or later

Pixel Scale is a very simple screen ruler.
It is calibrated in screen pixels, the major scale divisions being at either 40 or 100 pixels.
Pixel Scale can also be set so that the major scale divisions are at one centimeter or one inch intervals.

Sound Ruler is an analysis, graphing and teaching tool for bioacoustics Sound Ruler is open code and free and just like scientific knowledge, Sound Ruler is available for all to use, adapt, criticize for their needs and improve on.
Its visual interactive approach to analysis brings you the best of two worlds: the control of manual analysis and the objectivity and speed of automated analysis.
Sound Ruler gives special attention to simple, repetitive sounds, that can be quickly analyzed in great detail pulse by pulse for studies on populational variation.
Main features:
- Unrestricted sound file size: No need to edit your field recordings down to each call. You can keep long sequences in each file, in the way they were digitized. With Sound Ruler you can examine, analyze, filter, graph and run CCAs on the fly from the original long sequences, saving the positional information and filter parameters.
- Manual, automatic, or interactive recognition and measurement of calls and pulses: From Mouse logging to automated call recognition and measurement of 35 variables per pulse.
- Sound recognition based on amplitude, duration, frequency and/or interval
- Adjustable low-pass, high-pass or band-pass real-time filtering during the analysis: Remove unwanted sounds from a whole analysis with one click, without having to edit any files.
- Tuning curve filtering: Look, listen to and analyze your animal sounds through the ears of the natural receiver. This feature can also be used to easily design a variety complex filter profiles.
- Cross correlation analysis: Get your sound measurements and CCA analysis done at once with no extra effort!
- Have your bandpass filters and tuning curves applied to the calls on the fly, before the CCA.
- Perform simple or 2D CCAs, sliding spectrograms in the time and frequency axes.
- Amplitude calibration: Calibrate your measurements using reference signals in volts or decibels.
- Oscilograms, spectrograms and power spectra
- Editable and resizable figures with a refresh function for batch graphing: Customize a figure for size and arrangement of plots. Then select another call in Sound Ruler and click Refresh in your figure. The new data replace the old inside your ready figure.
- Copy figures and paste them into your text or image editor as bitmaps and metafiles.
- Export figures to seven bitmap and metafile formats, compressed or not.
- Measurements taken automatically are displayed graphically: When the computer takes the measurements, the results are plotted on the graphs, so you can inspect if the job was well done.
- You accept measurements, skip the call or change settings and reanalyze
- Easy navigation over previous results: The result navigator allows you to instantly move among the results for all calls in an analysis session.
- Four options for saving data: mouse log, textpad, spreadsheet or relational database: Depending on the analysis, it might be appropriate to just log your mouse clicking, or tell Sound Ruler to take some measurements and paste them into a text file, or save extensive amounts of data in spreadsheet or database ready format.
- Save raw measurements, calculated results and/or settings
- Explore acoustic scenarios with Sound Math: Let your students build hypothetical acoustic scenarios and explore how the properties of sound relate to each other and interact with the environment at the source, through the medium, at the receivers ears and inside the computer.
- No-edit graphing, filtering, tuning curve and CCA: Sound Ruler allows the students to do and undo several treatments and analyses to the sound file, without having to edit and save it. They can quickly experiment with and assimilate how physical processes influence call structure.
- Highly visual interface: Sound Rulers highly graphical interface and result display provide students with large amounts of sensory input that help them to make physical concepts sound intuitive.

Modometer is a mouse odometer that will let you monitor total right mouse and keyboard clicks Modometer is a mouse odometer that will let you monitor total right mouse and keyboard clicks.
Modometer was designed to let you calculate in real-time the distance travelled by the pointer on the screen.
Modomter tracks how far the mouse pointer has moved and how many keyboard and mouse button clicks have been made. Following each session, statistics, including average pointer speed, are outputed to the file "RootModoLog.txt".
Main features:
- calculates and can display in real-time the total pointer distance travelled,
- can display distances in a variety of metric & imperial measurements,
- the user must calibrate the modometer for their particular screen,
- keeps record of the number of left & right mouse clicks made,
- counts the number of keyboard clicks,
- its counters can be reset at any time,
- has a very unobrusive interface,
- runs silently in the background while the user works,
- can be made visible with a click in the windows tray,
- the user can specify to have it run at system startup.
System requirements:
- VB5 run-time files
