No I haven't. Is it like a spectragram?

Annabell
Have you tried the accessible spectrem analyzer?

Hi,
With the best will in the world, I think you might be trying to run
before you can walk here. Albert's right that a language like c++ is
probably best suited to the job, but how much information you can get
out of a pre-existing (and highly graphical) application will depend
more on what tools the original programmer(s) used to create the
application, rather than what tools you might have available. It might
actually be easier to write your own spectrogram application so that
you can ensure its accessibility right from the design stage. This
would be an interesting project, but not for the beginner, so I'd
advise taking some classes for beginner programmers and see how you
get on with it. You can argue that HTML doesn't class as a "real"
programming language, as it doesn't support decision-making very well
and iteration not at all. However, it's still a useful thing to learn
for its own sake, so please don't let my comments discourage you in
any way - HTML still requires you to think carefully about what your
code is going to do and that's a key component of the programmer's mind set.
Best wishes.

I'm starting to learn HTML. By the way, how would I obtain the
spectragram data that you describe? Would I have to do that with sighted
help?

Hi,
I can't imagine dealing with such a dynamic and graphic thing with
JAWS. I think you need to get the spectragram data and process it
yourself including doing some interpretations such as where peaks are
and maybe how wide they are.
Also, I think C/C++ would be the best language for this. What
languages do you know?

To create a non-visually-oriented spectragram? I'm hopefully going to
make ADX Trax Pro accessible to screenreaders, and I'm not sure how to
configure JAWS to recognize the components of a spectragram. One of
the guys at Audionamix, Steve Oliver, told me that the spectragram in
ADX Trax Pro consists of many shapes. Here's what he says.
<blockquote type="cite" class="">
Regarding the spectrogram: The spectrogram is a visualization of the
actual audio being processed. It is like a graph, where frequency (in
Hertz) is the Y axis, and time is the X axis. Because the information
is displayed dynamically, based on the sounds within the file, there
are no preset shapes like the ones you described.
For example, imagine an audio file of you speaking the sentence "Hi,
my name is Annabelle" while a police siren goes by in the background.
On the spectrogram, your voice would appear as stacks of wavy lines
(representing the fundamental frequency of your voice and the
corresponding harmonics above it). Each word would have its own stack
of wavy lines that would change depending on the word and how you said
it, and the unique characteristics of your voice. Also there would be
consonants sounds that might look like patches of noise in the higher
frequency range. The siren would look like a long line slowly curving
up and down from left to right.
If I said the words instead of you, these shapes would change because
of the qualities of my voice, and what speed I spoke at.
For these reasons there are almost infinite shapes that could be
displayed in the spectrogram. Do you have any ideas how that might
work with a screen reader? We'd certainly like to make it possible.
