This software is a free tool that generates digital audio watermark images with the GNU General Public License.
The software takes the scanlines of the input image and converts them into frequency components. It then uses an inverse Fast Fourier Transform to convert those frequency components into sound. The left side of the image is considered to be the low-frequency end, while the right side is the high-frequency end.
The supported audio formats in Enscribe include Microsoft WAV, Apple AIFF, Sun Microsystems AU, and raw output. The raw output can be sent to stdout, making it a versatile tool for any environment. The audio images created by Enscribe sound like a high-pitched buzzing or hissing.
One exciting feature of this software is its ability to encode color into the audio file. This is made possible thanks to the two-tone color display of Baudline, another software that works well with Enscribe. The default axes in Baudline are green and purple, but users can customize their display colors to their liking.
The author of Baudline, Erik Olson, had a great idea about encoding a third color channel using phase lag between the left and right channels. This feature can be activated by using the "-monet" switch in Baudline. This creates a pseudo-third color channel based on the differences in the signals from both channels. It may take some trial and error to get the hues right, but the result is certainly impressive.
Enscribe has some helpful switches that users can utilize to customize their output. The "-color=monet" switch sets Enscribe to encode color into the audio file, and the "baudline -monet" switch activates the third color channel in Baudline. Overall, Enscribe is a great tool for creating digital audio watermark images that are both unique and customizable.
