Suppress fast vario sound change #438

Open yves1982 opened 3 years ago

yves1982 commented 3 years ago

The fact that the variometer uses accelerometer gives very direct feedback, but it's also very "nervous", especially in turbulent air. After switching from Skytraxx to SkyDrop, i didn't really get used to it. That's why I finally turned off the "use accelerometer" flag in the Variometer settings - now it feels much more calm because delayed in a kind of way.

The disadvantage of this is that there is still the little delay between the start of the rise and the vario sound (which use of the accelerometer tries to fix).

It would be nice to have a setting that allows to "flatten the curve" respectively limit/delay the change of the tone in a certain time range.

Found out there is a setting called "Digital vario averaging, in s", but this doesn't affect the sound.

The Digital vario averaging is only for the widget (display only). With the real-time filtering, there is always trade off between smooth output and response time. The smoother curve will introduce delay in the audio. Maybe we can change the on/off nature of the accelerometer to percentage, so you can fine-tune the gain of the vario.

Will that work for you?

Hi!

Yes, this could be a good solution! Of course to be tried in the air :-)

Thanks
