[Rwp] ReaAccess no longer available

[Fiore Martin]

Scott actually your idea doesn't sound bad at all, if I understood it
correctly.
I am thinking we could have the frequency spectrum divided in three sectors
: low, mid and high frequencies
low sector going from 20 Hz to 250Hz, mid from 250 Hz to 2.5 kHz and high
from 2.5 kHz to 22kHz

One control would allow to choose in which sector the selection operates.
And then you would have three different selection controls to set the
selection start and size into each sector.
This way the three different controls would have a different resolution
that suits better the sector they relate to.
Small increase steps for low frequency sector and big increase steps for
high frequency sector.

Not sure if I am making sense to you but it sounds sensible to me


Snowman: you can have a go at the draft number 1 I published at the
following links and tell me what you think about it !

VST plugin 32 bit  for Windows
<http://depic.eecs.qmul.ac.uk/sites/depic.eecs.qmul.ac.uk/files/AccessibleSpectrumAnalyser_draft1_32bit.dll>

VST plugin 64 bit  for Windows
<http://depic.eecs.qmul.ac.uk/sites/depic.eecs.qmul.ac.uk/files/AccessibleSpectrumAnalyser_draft1_64bit.dll>

AU plugin for Mac
<http://depic.eecs.qmul.ac.uk/?q=system/files/AccessibleSpectrumAnalyser.component.zip>,
drop it in /Library/Audio/Plug-ins/Components

> Usage:
>
> You can select the range of frequencies you want to monitor  by setting
> selection-start and selection-size parameters.
> 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
> 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.
>
> 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.
> 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.
>
> at the moment only the frequency component with the biggest magnitude in
> the selection is taken into account for the sonification
>
> dry and wet parameters are for volumes of the original audio and the
> sonification respectively.
>
>
> And now some questions if you'd like to answer any of them :
>
> 1) would you find this plug-in useful ?
>
> 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
> to indicate if the selection and hence the sonified frequency components
> are towards the low end of the spectrum or the high end.
> However this information might be redundant since you set the selection
> yourselves and you know already where it is?
> Another option could be to use panning to give information about the
> location of the peaking frequency components within the selection.
>
> 3) would you prefer to have the sound of all the frequency components
> passing the threshold in the selection rather than the biggest ?
> 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.
>
> 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 ?
>
> 5) Would you prefer to have a selection-end parameter rather than
> selection-size or doesn't really matter ?
