A downloadable tool for Windows

BrushTone is an accessible Paint Tool for the blind and visually impared that allows users to view, modify, and create images purely using sound.

So, how does it work? Each pixel is represented by 3 values, Red, Green, and Blue. These RGB values are in turn represented by 3 sequential beeps, the pitch of each beep represents how bright each color value is, the higher the pitch, the brighter the color, the lower the pitch, the darker the color.

It has a variety of tools and functions, including but not limited to:

Pencil, Line, Square, Filled Square, Circle, Filled Circle, Flood Fill, Select, Cut, Copy, Paste, Flip, Rotate, Stretch, Skew, Invert Colors, Grey Scale, Adjust RGB, Cycle Colors, RGB Explode, RGB Condense, Slice, Stitch, and Alpha Channels with an Alpha Paint Mode.

It comes equiped with a window scan function, including Peter Meijers Image to Sound algorithm, as well as animation playback. Compatible formats include PNG, BMP, JPG, and GIF.

Version 1.1 now includes Braille Display support.

Version 1.2.5 now includes Screen Reader support for NVDA, Jaws, Windows-Eyes, SuperNova, System Access, and ZoomText.

If you encounter any performance issues, try to Disable Display Scaling on High DPI Settings and run it in compatibility mode for WinXP SP3.
