GCS with audio rate of climb (vario)

Posted by Matthew Coleman on March 27, 2011 at 12:23am

Is there a GCS that gives audio feedback on rate of climb?

Audio feedback of changing total energy (potential plus kinetic) would be better.

I would very much like to see this on HK GCS but HK is quite busy with other features already.

Is anyone else interested in this feature?

I vote for the tuba! You can really go down in style with that one.

On a more serious side; thanks for the GCS Happy. It is a great piece of software. Ihope You get a lot of donations.

More on DirectSound. It is not so easy to get started.

I cant seem to get a variable dimensioned on the DirectX library.

The DirectSound library has been referenced into the project but that didnt help much.

I hope your experience with DirectShow/graphics can help out.

HK,

Thanks for the response. I see you have been quite busy recently.

Here is an audio example up a varying upwards scale

http://www.flyaboveall.com/malflight.wav

The downwards scale is similar but uses lower tones

I have now downloaded your source code and am trying to add something that sounds right.

Console.Beep is no good. It can not do fast repetition rates. Probably limited by the console service interrupt rate.

Beep() has disappeared out of win64. Forget it.

My.Computer.Audio.PlaySystemSound(Media.SystemSounds.Beep) works but is just plain wrong

I am not sure this is likely to work since the.wav would need to be played at compressed or expanded speed.
```
My.Computer.Audio.Play("C:\nameof your play.wav", AudioPlayMode.Background)

This is the best clue I found so far for playing direct sound. Needs investigation.

Can you give me an example? I have almost completely disregarded vertical speed for the last few months. This shouldn't be that difficult for me to add....
