Vario tone options

Which board (stock / gruvin9x / sky9x / Taranis) are you using?
Taranis

Hello Bernet,
the Vario tone of Taranis goes from min. 640Hz over 1000Hz at 0m/s to max. 
2000Hz. Correct? It sounds good.
However, the Vario pilots from the great sailplanes love a lower frequency 
location.
So at 0m/s approx 300Hz down to 10Hz at -4m/s sinkrate.
I know, the lowest steps are limited by the timer. Often only a coarser 
gradation of frequency is possible. I think this is no problem at the low end.
What do you think about my proposal.

An other point:
Particularity of the three different variometer sound schemes
It is very important for the pilot to know in which of these three areas he 
actually is. In order to distinguish these three areas three different tone 
schemes have been set up. The zero lift area is particularly valuable.

The sinking below the sinking threshold is indicated as usual with a continuous 
tone the frequency of which becomes lower at increasing sink rate. Climbing is 
always indicated with an intermittent tone the frequency and pulse rate of 
which increases with increasing climb rate.
In the zero lift area you will hear no tone.
This way real climbing, start of climbing within the zero lift area as well as 
sinking can easily be distinguished one from another.
This particularity has been adopted from wsTech variometers by some tramsmitter 
firwares.
Nonetheless the thresholds are configurable per model by the user in the vario 
menu.

Best regards,
Wolfgang

That's exactly how it works.

Avout the frequencies we simply found that the lower frequencies sounded bad, 
and due to the timer resolution the sound "steps" became too big.

All of it is subjective of course. If you want you can try to play with it, 
change the code and submit if you find something better.

Thanks for feedback.
We try to modify the code.
Best regards,
Wolfgang
