<DIV><BR></DIV>
<DIV dir=ltr>Hi all,
<DIV><BR></DIV>
<DIV>Does anybody know where I can get a copy of ReaAccess for windows ? The
domain of the website seems to be expired.</DIV>
<DIV><BR></DIV>
<DIV>By the way, the reason I need it is to test a plug-in I am working on at
Queen Mary University of London called Accessible Spectrum Analyser, which
sonifies frequency spectra</DIV>
<DIV>in order to make them accessible. </DIV>
<DIV><BR></DIV>
<DIV>more info and link to the first prototype below and if you'd like to give
some feedback, I am all ears</DIV>
<DIV><BR></DIV>
<DIV>thank you </DIV>
<DIV>Fiore </DIV>
<DIV><BR></DIV>
<DIV><BR></DIV>
<DIV><BR></DIV>
<DIV>Links for plug-in download:</DIV>

plugin for Mac</A>, drop it in /Library/Audio/Plug-ins/Components</DIV>
<DIV><BR></DIV>
<DIV>Usage:</DIV>
<DIV><BR></DIV>
<DIV>You can select the range of frequencies you want to monitor by
setting selection-start and selection-size parameters. </DIV>
<DIV>For example if you'd like to monitor the frequencies from 20Hz to 1Khz,
you want to set selection start to 20Hz and selection size to
1880Hz </DIV>
<DIV>So once the selection size is set, by moving the selection start
parameter, you can scan the whole spectrum from low frequencies to high
frequencies. </DIV>
<DIV><BR></DIV>
<DIV>Then to activate the sonification, you want to tweak the threshold
parameter: when any of the frequencies in the selection goes above the
threshold, the plug-in will beep at 440Hz plus one semitone per db
of difference between the frequency component and the threshold. </DIV>
<DIV>For instance if your audio has one frequency component whose magnitude is
-3db and you set your threshold at -2db you will hear an A#, which is
given by 440Hz (A) plus one semitone for the 1 db difference.</DIV>
<DIV><BR></DIV>
<DIV>at the moment only the frequency component with the biggest magnitude in
the selection is taken into account for the sonification </DIV>
<DIV><BR></DIV>
<DIV>dry and wet parameters are for volumes of the original audio and the
sonification respectively. </DIV>
<DIV><BR></DIV>
<DIV><BR></DIV>
<DIV>And now some questions if you'd like to answer any of them : </DIV>
<DIV><BR></DIV>
<DIV>1) would you find this plug-in useful ? </DIV>
<DIV><BR></DIV>
<DIV>2) would you prefer to have some indication in the sonification of where
the selection is in the total spectral range. For example I could use
panning </DIV>
<DIV>to indicate if the selection and hence the sonified frequency components
are towards the low end of the spectrum or the high end. </DIV>
<DIV>However this information might be redundant since you set the selection
yourselves and you know already where it is? </DIV>
<DIV>Another option could be to use panning to give information about the
location of the peaking frequency components within the selection. </DIV>
<DIV><BR></DIV>
<DIV>3) would you prefer to have the sound of all the frequency components
passing the threshold in the selection rather than the biggest ? </DIV>
<DIV>In this case the sound would be made out of a lot of sine waves with
different pitch (one per component) and obviously the pitch would no longer be
linked to the difference with the threshold. I am afraid this would turn out
to be quite noisy though.</DIV>
<DIV><BR></DIV>
<DIV>4) how easy/hard is it for you to handle parameters which such a big
range like the selection start going from 20 to 20.000 ? </DIV>
<DIV><BR></DIV>
<DIV>5) Would you prefer to have a selection-end parameter rather than
selection-size or doesn't really matter ?</DIV>
<DIV><BR></DIV>
<DIV>Thanks</DIV>
