An itch (pruritus) is a sensation in the skin that elicits the desire to scratch. Itching is caused by an irritation of the nerve endings for pain and touch, sometimes accompanied by inflammation or skin eruptions. The difference between itching and pain is one of degree; a lowered threshold for stimulation in skin areas around the site of irritation usually leads to itching and scratching. The cause of the irritation may be mechanical, such as a chafing collar; biochemical, such as an allergic reaction or an insect bite or due to invasions of the skin, such as the fungus infection ringworm or the mite infestation scabies. A persistent itch may be a symptom of some systemic disease, such as a liver disorder. Research Itch
ATRAC is an abbreviation for Adaptive Transform Acoustic Coding, and is the digital audio encoding method used in minidiscs. The algorithm divides the 16 bit 44.1 KHz digital signal it receives into 52 sub-bands in the frequency domain (after a Fast Fourier Transform). A psycho-acoustic transfer function that takes advantage of the masking effect and the absolute hearing threshold then removes enough information to reduce the data stream to 1/5th of the original size. Each channel receives that treatment separately (the Sony MZ-1 portable MDrecorder features one ATRAC encoder/decoder chip per channel). Earlier versions of ATRAC, prior to version 3.5 were noisy, adding noise to recordings which could be heard during silent or very quiet passages in the audio recording. Later versions, 3.5 and onwards, are comparable to CD quality when listened to by the humanear. The first version of ATRAC had a frequency response up to 15 kHz, by version 3.5 that had increased to 18 kHz and version 4.5 reached 20 kHz. Research ATRAC
In audio engineering a compander is a compressor/expander - a combination of signal compression and expansion. The compander attenuates the input signal above the threshold as well as the level below the width. For very dynamic material, this device allows you to retain the dynamic range without having to be concerned with excessive output signal levels and clipping. Research Compander
Ducking is an audio engineering term used to describe the automatic reduction of signal levels when the level of a source signal exceeds a specified threshold. It is used for voice-over applications where, for example, level of background music is automatically reduced, allowing an announcer to be heard clearly. Research Ducking
In audio engineering an expander is a form of automatic level control. By attenuating the signal below the threshold, the expander reduces low-level noise or expands the dynamic range of the recorded material. Research Expander
In audio engineering a gate or noise gate is an audio switch used to mute signals below a set threshold level. It can be used to suppress background noise and hiss from valve amplifiers, effects pedals, and microphones. Research Noise Gate
VirtualDub is a computer program for the Windows operating system for capturing video with video for windows compatible devices. VirtualDub also offers facilities for fractional frame rates; optimised disk access for more consistent hard disk usage; the capacity to create AVI2 (OpenDML) files to break the AVI 2GB barrier and multiple files to break the FAT32 4GB limit; An integrated volume meter and histogram for input level monitoring; real-time downsizing, noise reduction, and field swapping; verbose monitoring, including compression levels, CPU usage, and free disk space.
VirtualDub enables the user to access hidden video formats your capture card may support but not have a setting for, such as 352x480.
VirtualDub also lets you clean up video on your computer. VirtualDub isn't an editor application; it' s a pre- and post-processor that works as a valuable companion to one: with facilities to read and writes AVI2 (OpenDML) and multi-segment AVI clips and has integrated MPEG-1 and Motion-JPEG decoders. VirtualDub enables you to remove and replace audio tracks without touching the video. Also provided are an extensive video filter set, including blur, sharpen, emboss, smooth, 3x3 convolution, flip, resize rotate, brightness/contrast, levels, deinterlace, and threshold.
VirtualDub supports decompressing and recompressing of both audio and video, and allows you to remove segments of a video clip and save the rest, without recompressing. Research VirtualDub
The Common Agricultural Policy (CAP) is a policy set up by the European Economic Community to support free trade within the Common Market and to protect farmers in the member states. The European Commission fixes a threshold price, below which cereals may not be imported into the European Community (EC), and also buys surplus cereals at an agreed intervention price in order to help farmers achieve a reasonable average price, called the target price. Prices are also agreed for meats, poultry, eggs, fruit, and vegetables, with arrangements similar to those for cereals. The European Commission is also empowered by the CAP to subsidize the modernization of farms within the community. The common policy for exporting agricultural products to non- member countries is laid down by the CAP. In the UK, the Intervention Board for Agricultural Produce is responsible for the implementation of EC regulations regarding the CAP. Research Common Agricultural Policy
