XACT Doppler Problem

    XACT Doppler Problem

    Reply Quote

    Hello everyone,

    I'm trying to get doppler working with certain sound in my game.
    I'm actually not too far off. What 'm hearing is the doppler effect but not interpolated.
    I hear it either all pitched up when I'm approaching the emitter or all pitched down when I'm departing from the emitter.
    XACT throws these warnings:

    [XACT] [XACT::CVariable::SetVariable] [time 0:57:23.645] Warning: Variable value (1.#INF00) out of range [0.000000, 4.000000]

    [XACT] [XACT::CVariable::SetVariable] [time 0:57:24.635] Warning: Variable value (-1.#INF00) out of range [0.000000, 4.000000]

    Does anyone know this issue? Thanks for the help!

    For those that might also have this issue.
    I was able to fix it. In my case my project's global variable "SpeedOfSound" was altered.
    The default value for Init Val and Value is 343,5. For some reason we had a 0 there.
    Also the Range is default 0-1000000 and not 0-20 as in our case.

    Hope this helps someone.
