Licensing: You may download the software for free. However, certain features are restricted, and images are watermarked with a grid pattern when you save them, unless you purchase a license. See the purchase page for details.

Compatibility: For Linux a Pentium III compatible or better processor is required. For AMD processors this translates to an Athlon XP processor or better.

Note: If you have a "Home to Professional Upgrade" keycode, please contact us for a Pro Standalone replacement key. We are phasing out distinct upgrade keys in the latest version of Noise Ninja standalone (we issue actual Pro keys now for upgrades). If you have already upgraded to a Pro Bundle license, it will work with the latest version.
