3D DirectSound, volume of the sound

3D DirectSound, volume of the sound

3D DirectSound, volume of the sound

(OP)
Hi,

We' re currently developing a 3D sound system for a driving simulator. But we having difficulties with the volume of the sound.

If a sound (other car) passes our own car, it's volume is very low.
The factors aal are set to 1.0 (Rolloff, doppler and distance)
If we set the rolloff to 0.0, the sound is much louder (offcourse, its original volume)

The minimum distance is set to 50.0 meters. The car passes at a disance of 3 - 4 meters.

Does anyone know why the volume of the sound is decreased by DirrectSound????

thnx Pjotr

RE: 3D DirectSound, volume of the sound

i think the sound volume is logarithmic, maybe your trying to set it as if its linear

I do use a linear scale, but it is translated to a logarithmic value.
This section has been doublechecked many times.

but thnx for the suggestion
