Free compression tool software for windows

TC is an experimental command-line file compressor with fast decompression speed. It uses a ROLZ like compression engine.
Main features:
- High compression ratio
- Fast decompression speed (~4...15 MB/sec)

Stereo Tool is a Winamp plugin that can be used to manipulate sounds.
It contains a singleband compressor, an 8-band multiband compressor, a lowpass filter and a stereo image manipulator.
The compressors can be used to make the playback volume and sound of different recordings more equal, or to remove loud peaks from recordings.
The stereo image manipulator can be used to repair phase shift problems in stereo recordings and to increase or decrease phasing and channel separation separately. It can also be used to convert sounds from stereo to mono, while preserving the fullness of the sound.
The lowpass filter is useful if certain frequencies need to be filtered out, for example the FM stereo pilot tone at 19 kHz if you send the Winamp output to an FM transmitter.

Image Compression with Neural Networks 1.0 is a very flexible and effective mathematic tool which have been applied to many problems, and have demonstrated their superiority over traditional methods when dealing with noisy or incomplete data. One such application is for image compression. Neural networks seem to be well suited to this particular function, as they have the ability to preprocess input patterns to produce simpler patterns with fewer components. This compressed information (stored in a hidden layer) preserves the full information obtained from the external environment.
