Hello,
I know I’ve been asking for so much lately, but I have yet to find a Screen-reader-accessible plugin that generates a sweep or chirp while still having a duration edit box. So due to both accessibility and being auditorily picky, I think people might benefit from an “HQ Sweep” or “HQ Chirp” Nyquist plugin. Unfortunately, given that I am not too familiar with Nyquist, I can explain what the controls would be.
“Waveform:” the same choices as in the HQ tone plugin
“Frequency Hertz start”, “Frequency Hertz end”, “Amplitude start”, “Amplitude end”, whatever the control label would be with choices “Linear” and “Logarithmic”, and finally “Duration”, edit box (rather than a series of read-only stuff that Jaws can’t handle as in the standard chirp plugin). Only now, this plugin will make it so that the waveforms that use higher harmonics are bandlimited, exactly how it is in the HQ tone plugin. I don’t think this would take too much effort to make, though if I knew Nyquist, I’d use the “HQ Tone” plugin as a place to base the HQ sweep on. Is it possible that anyone could attempt to try this? I’d love to have such a plugin, but for two reasons, I am not the biggest fan of the standard chirp. 1) At least with a screen reader, you can’t type a duration, which needs to be accessible (the HQ tone duration box does work with screen reader), and 2) This ridiculous distortion effect I can’t handle, just like the warping on old bagpipe records which I have. Thanks, sorry for the inconvenience, and good luck.
Michael
PS. After this, I seriously can’t think of any more plugins to suggest.
