Noise Ninja is an inherently computing-intensive software application. Generally speaking, the faster your computer and the more memory available, the better Noise Ninja will perform. Below, we describe the minimum and recommended computer configuration for using Noise Ninja.
Noise Ninja runs on the following operating systems:
For Windows, a Pentium-compatible processor is required, and a Pentium III or better processor is highly recommended.
For Macintosh, a G3 processor is the minimum supported, and a G4 or better processor is highly recommended.
Best peformance will be obtained with 1GHz or faster processors. Noise Ninja is particularly optimized to exploit advanced features on the Pentium 4 and G5 processors.
Noise Ninja uses a disk-backed caching system that can process large images in modest amounts of memory. However, performance will be best when plenty of free memory is available. As a rule of thumb, it is best to have roughly 20 bytes of free memory per image pixel. So, for a 6 megapixel image, 120 megabytes of free RAM should yield good results.
Noise Ninja uses the hard disk as a "scratch area" to temporarily store image data that it can't fit in RAM. The amount of free disk space that you need depends on the size of images that you intend to process and the amount of RAM available to Noise Ninja. As a rough guideline, figure on needing around 96 megabytes for a 6 megapixel image, and more if you intend to open several images at once.
In the Preferences dialog, you can specify the location for the scratch area. Ideally, you should specify a disk that has several gigabytes of free space.
