Qt GameEnabler only low volume?!

[whiteF]

hi, i tested the following 2 Audio Methods
--> Qt GameEnabler - QML Audio Plugin ("GEAudio 1.0")
--> Audio/Soundeffect Elements ("QtMultimediaKit 1.1")

After testing, I noticed the following:

--> Qt GameEnabler - QML Audio Plugin ("GEAudio 1.0"):
- Quick Sounds / fast reactions
- low volume

--> Audio/Soundeffect Elements ("QtMultimediaKit 1.1")
- Slow Sounds / slow reactions
- higher volume than Qt GameEnabler - QML Audio Plugin ("GEAudio 1.0")

With Qt GameEnabler - QML Audio Plugin ("GEAudio 1.0") i had tested with
- "Mixer.AbsoluteVolume: 1.0"
- "AudioBuffer.Volume: 1.0"

Does anybody know how i can output sounds with Qt GameEnabler - QML Audio Plugin ("GEAudio 1.0") without to set any volume above "1.0" ?!


At least...
my ringtones are louder as the same ringtone played with Qt GameEnabler - QML Audio Plugin ("GEAudio 1.0")... why?!

The app "Dj Turntable v1.4" from https://projects.developer.nokia.com/turntable also playing low volume sounds (This App uses Qt GameEnabler - QML Audio Plugin ("GEAudio 1.0") too)

nobody can hear that sounds if people in front of you talk together... rly awesome

This may depend on multiple things; the volume of your audio samples, the number of audio sources used in the GE mixer, and also the version of your Qt Mobility installation.

GameEnabler uses QAudioOuput internally, and QAudioOutput has a known issue with volume setting:
https://bugreports.qt-project.org/browse/QTBUG-23771

GE actually tries to work around it, see here:
http://projects.developer.nokia.com/...dioout.cpp#L79

Even with the hack enabled, it caps the volume to 60% of the maximum (and does nothing on the latest Mobility release, where the problem is reportedly fixed).

But you have to enable it yourself by defining QTGAMEENABLER_USE_VOLUME_HACK:
http://projects.developer.nokia.com/...raudio.pri#L81

Finally, you should remember that GE is a software mixer that doesn't provide protection (compression/limiting) against audio clipping, so with multiple audio buffers running with high volume levels, there is the risk of distorted output. This is the reason why GE uses conservative volume levels in general.

I will also add:
Usually the volume by the GE mixer is ok. It might not be super loud on all environments, but that is rarely what people want. If they are in environment where lot of people are talking etc. they would use their headphones or simply cope with no sound.
