I know this is a question for a very small amount of users, but one suggestion, I'm blind and using a screen reader to navigate StereoTool's web GUI, as the main GUI does not work with NVDA (name of my screen reader).
Sliders read out from the screen reader as web__widget_s, and buttons read as web__widget_off_l, web__widget_off_m, web__widget_off_r, etc.
Can you add alt tags to the graphical elements on the web interface to allow StereoTool to play nice with my screen reader please when you get a chance? More information about the HTML alt Attribute is below.
Another thing, it would be nice if I could move the sliders with the keyboard and not only the mouse for the web GUI. The mouse slider moving is dueable, however keyboard allows for more precise adjustments for anyone I imagine, not just the blind.
Thank you for this great program!
