Free adding to the noise software for windows

AbsoluteDeNoiser is an easy to use application that produces very competitive noise reduction filtering for digital images.
Digital cameras or scanners often produce images that contains noise, especially when using high ISO. This noise is made of random pixel variations that damage the picture in different manner, adding unwanted granular effects.
Main features:
- Edges detection : this analyse makes a separation between large surfaces with poor details, and places where some edges and/or details require a special attention. The value to tune enables to decide the sensitivity of the edges detection, thus the amount of the picture that is to be considered as details/edges or not. Surfaces and edges will then be processed in different ways in next steps.
- Surfacing : performs a calculation of local color cohesion to decide, for each pixel, what is the mean color value in the noise variations arround it, without merging two different surfaces together. This step also processes surfaces and edges in two different ways. The more important is the value that tunes the surface managment : it is the one that decides of the effective noise reduction. There is also a secondary value that tunes the edges managment, but it should often be kept at a low value to avoid bluring edges : in some cases it offers the possibility to reduce some edges pixelisation effects.
- Texturing : the step 2 may provide with "too" clean surfaces where some small details or textures could have been lost, and possibly a "plastic" effect. This final filter decides the amount of original pixels that should be added back to the clean surface to restore details and textures without re-introducing the noise that should be removed. A first value tunes how much part of pixels that was removed in step 2 shows a local regularity, thus how much noise vs details is to be considered on them. There is also a secondary value that tunes how much pure granularity, without special regularity, should be added back without re-introducing bad strong spots and scratches.

Audio denoising software that uses new technologies to remove (without filtering) noise out of digital audio recording. Digitized old LPs and other recordings are turned into almost-CD-quality sound files.

When you offer several choices in a menu, you may want to implement the radio button-style selection feature popular in Windows 95. Written for VB5.Requires the VB 5.0 Runtimes.

The AMS audio masking system is a free tool that uses a Windows PC to create pink noise tones to assist to mask confidential sensitive background conversations. Typically AMS is used in waiting rooms to reduce the ability to overhear confidential conversions but it can also be used as a security device to prevent the interception of sensitive conversations.
A sound will always mask a background sound. However the problem with most sounds is that the masking only occurs at the sounds frequencies which, with for example music, is rarely all frequencies and never the same as voice. The listen hears the background conversation through the gaps in bands of the music.
Pink noise is a sound that sounds a bit like the sea and has all frequencies combined together. AMS creates Modified Pink Noise, pink noise with a spectrum most similar to voice. This is proven to be the most effective sound to prevent hearing background conversations. So just like a background conversation would be less likely to be overheard at the sea, a background conversion is less likely to be overheard when AMS is playing. The added advantage of pink noise, like the sound of the sea, is that while you notice the sound when it first turns on after a short while the brain turns it off so you stop noticing it. The masking effect however continues.
You only need a fairly soft sound to dramatically reduce the intelligibility of background conversations. In more severe cases you can combine AMS with dynamic-range compressed music (you can use the BMS Business Music System).
Install AMS on any Windows PC with a sound card. Move the computer speakers to between the conversation and potential listeners and adjust the volume (very soft noise can be effective). AMS will automatically start when you turn on your computer and runs in the background 24/7. You can continue to use your PC as normal while AMS sits on the task bar tray.
