Subject: [ddots-l] Fw: Accessible Spectrum analyser
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 of a
signal as a graph in real time.
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
trespasses a threshold or it can sonify the level of selected bins.
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 frequency bin
to a note. The idea being that you can produce chords out of the bins
in the 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
suggestion would be welcome
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
Fiore
