I just updated the audio aspects of the app, pushed the code to GitHub, and uploaded version 0.3b(4) to Google Play. Apart from a few little bug fixes the new things are:
- Added preferences (in Setting|Vario|Audio) for:
- Vario Audio Threshold - Above this value the vario starts beeping. The default is 0.2m/s
- Vario Audio Cutoff - Below this value the vario stops beeping. The default is 0.05 m/s. This means that the vario continues to beep during the range 0.5 to 0.2 m/s.
- Sink Audio Threshold - Below this value the the sink Alarm sounds. The default is -2.0 m/s. The current sink alarm is a pleasant female English voice saying "Sink-Sink-Sink..." Should you not want to hear it set the sink alarm to something like -10.
I have not implemented it yet, but I do intend to change the speed of playback if the sink is greater (more sink = slower playback = lower pitch).
