Hi all,
just to let you know the Accessible Spectrum Analyser VST/AU plug-in is now
available online for free at http://depic.eecs.qmul.ac.uk/apm/spectrum.html
thank you
all the best
Fiore

Hi all, thank you for your replies, very helpful indeed.
As for the secondary audio source, I am aware of the set up that involves two
separate channels for audio content and screen reader voice.
However this is a very tricky set up to reproduce in a plug-in, hosted by a
third party software.
Our former plug-in, the accessible peak meter, comes in a special version for
two sound cards
but this is a sort of hack of the VST protocol and it has many limitations

yes this is an excelent idea!
I like all of the proposed ideas. For me at least, just knowing which
frequencies poke above a user-defined threshold will speed up my
workflow. Agree also that any sounds this makes should come out of a
secondary/less important audio source, i.e. the same one that our
screen reader is coming through - if that is possible. if not, it's
ok coming through the monitors .

Fiore,
I for one am blown away by what you are proposing for a spectrum
analyzer. I think your examples are tremendous ideas.
I have one question and perhaps one comment for now.
For your beeps, would they be routed to the sound card where maybe the
screen reader resides or to the card where we do our work.
I would suggest the screen reader card by default but allowing options
to pick any other card on board?
I would recommend being careful to make the interface totally
accessible as well as what sounds it produces.
By the way, I love your idea of forming a chord of tones for the
fequency spectrum. That's just awesome.
usable tasks:
* de-essing. It can get quite laborious now.
* identifying frequency issues in multiple instruments or instrument
vocals that occupy the same space in a mix.
* Then of course, to clear up any residual issues in a mix during mastering.
Thank you,

Dear Dancing Dots list,
following on from the kind advice of Bill McCann, please find below a call
for end user feedback for an audio plug-in
I am developing for visually impaired musicians and audio producers.

Fiore Martin here, from Queen Mary university of London. I developed the
Accessible Peak Meter, a VST/AU/AAX plug-in which
makes peak meters accessible. More info on the plug-in at :
http://depic.eecs.qmul.ac.uk/apm/
I am now in the process of developing another plug-in, the accessible
spectrum analyser.
The idea is more or less to use the same sonification strategy as in the
Accessible peak meter, but this time to make frequency spectrum graphs
accessible.
I am about at the point where I can scope the frequency spectrum
as a graph in real time.trespasses
So I am now trying to figure out useful sonifications based on the tasks
that you guys normally carry out when recording/producing
So imagine you have a tool that sonifies the frequency spectrum somehow.
For instance it can emit beeps when the power of some frequencies
a threshold or it can sonify the level of selected bins.frequency bin to a
Could you think of what information you would like to get from it ? Namely,
how would you put it to good use in your tasks ?
A few examples off the top of my head:
- select a range of frequencies, say from 20Hz to 200Hz, and emit a beep
each time any of these frequencies goes past a threshold value
- select a range of frequencies and map the level of each
note. The idea being that you can produce chords out of the bins in thesuggestion
range and see if it is similar to the chords produced by another channel of
the mix. This way you notice if two instruments overlap and phase cancel
each other
- play all the frequency bins that go past a certain threshold, each with a
pitch mapped to its position in the frequency spectrum. so you know which
the fundamental and harmonics frequencies are.
These examples were just to give you an idea of course: any other
would be welcomePLEASE READ THIS FOOTER AT LEAST ONCE!
Also it would be great if you could specify the tasks in which you'd find
any sonification strategy useful.
looking forward to hearing from you
all the best
thank you
