Free interchange software for windows

HSL Interchange 1.1 is developed to be a useful tool with which you can have two-way conversations from your computer to mobile/cell phone users. Using SMS (Short Message Service), text messages can be sent to a mobile and received from a mobile just like regular instant messaging. Requires an Interchange or SMPP SMS account.

Requirements: Windows NT/2000/XP

Playlist Manager is an application for managing and interchanging media in Fx Magic Music, Windows Media Player and Winamp audio playlists.

Xiao Steganography will hid data in image and audio files Xiao Steganography is an application that will hid data in image and audio files.
Steganography is the art of covered or hidden writing. The purpose of steganography is covert communication to hide a message from a third party. This differs from cryptography, the art of secret writing, which is intended to make a message unreadable by a third party but does not hide the existence of the secret communication.
Although steganography is separate and distinct from cryptography, there are many analogies between the two, and some authors categorize steganography as a form of cryptography since hidden communication is a form of secret writing (...)
The most common steganography method in audio and image files employs some type of least significant bit substitution or overwriting. The least significant bit term comes from the numeric significance of the bits in a byte.
The high-order or most significant bit is the one with the highest arithmetic value (i.e., 27=128), whereas the low-order or least significant bit is the one with the lowest arithmetic value (i.e., 20=1).
As a simple example of least significant bit substitution, imagine "hiding" the character G across the following eight bytes of a carrier file (the least significant bits are blue):
10010101 00001101 11001001 10010110
00001111 11001011 10011111 00010000
A G is represented in the American Standard Code for Information Interchange (ASCII) as the binary string 01000111. These eight bits can be "written" to the least significant bit of each of the eight carrier bytes as follows:
10010100 00001101 11001000 10010110
00001110 11001011 10011111 00010001
In the sample above, only half of the least significant bits were actually changed (shown above in red). This makes some sense when one set of zeros and ones are being substituted with another set of zeros and ones.
Least significant bit substitution can be used to overwrite legitimate RGB color encodings or palette pointers in GIF and BMP files, coefficients in JPEG files, and pulse code modulation levels in audio files.
By overwriting the least significant bit, the numeric value of the byte changes very little and is least likely to be detected by the human eye or ear.

ELMathSolver .NET 2.3 is developed as a library which can parse string as a mathematical formula and draws 2D and 3D charts. ELMathSolver.NET is very simple and elegant in using. You can use library in your projects written in C#, VB.NET or ASP.NET.

Convert Audio Interchange File Format to WAVE file format Aiff To Wave Converter is a simple application that will help you convert Audio Interchange File Format (ie, AIFF -- a digital audio file format often used on the Mac) to WAVE file format (ie, the format mostly used on Intel-based computers).

Image Processing Evaluation System (IPES) is a develpment environment for the industrial picture processing.
With IPES you can analyse the image data and develop your own the image processing algorithms.
