bit rate/sampling depth confusion

Hi all,
 
Just started using MC6. Created a couple of basic tracks, exported to audio. Audio plays back about half-speed. Checked the help and forums and I gather I'm running into a sampling rate issue (I think) where I've recorded something at one speed (44khz, 24-bit) and my laptop wants to play it back at half speed. I've tried a lot of different variations of sampling rates and bit depths and can't get a different result.
 
Using fairly new tech/sound card and Win 7. What am I missing?
 
Any help would be appreciated!

    when you exported, what were your export settings?  did you export at 44.1kHz/24bit?

    I exported at 44k/22-bit and when that didn't sound right started experimenting with different rates. Looking at the audio file properties that I try to play it says it's at 64 bit.

    export at 44.1kHz/16bit.  that's CD quality.

    the different bit rate shouldn't cause you to have slow playback, tho.

    Generally when you use different sampling rates on 2 different machines, you can have this sort of issue.

    You can try converting it or set the sample rate on the second playback machine.

    A better option is to use 44.1k/24 bit as your standard setting for recording.  As Beagle points out 44.1/16 is standard CD quality. use it and you're safe. especially to export projects and tracks

    Thanks for the input. MC6 defaults to 24-bit, that's what it was in when I started it up. I then tried switching it to 16-bit since that's pretty good for what I'm doing, and nothing in the project changed, even when I set the import filter to 16bit ... it still shows everything in the project as 24-bit. Relaunched the program, no change.
     
    I suspect I've got a setting somewhere on my soundcard that the program slaves to. Does that make any sense?
     
    Just made it work while exporting to a WMF ... seems to be the only format that doesn't play back at half-speed. Weird.
     
    Thx for your help so far, and any techie expert please chime in LOL
     
    Laters all!
    FIGURED IT OUT: it's the media tab on the right of the interface that's buggy -- if you try to play your sample back thru that tab it slows waaaaaay down LOL. Guess you just have to go test your stuff from outside MC6.
     
    Thanks again all who responded.

    you DO want to record at 24 bit to give you more headroom for mixing.  but EXPORT at 16 bit wave files because that's what the standard is for CD quality (and not all systems will play 24bit files).

    Playing the file half speed would mean a 100% difference in sampling rate, as bit depth has no effect on playback speed. I doubt there can be a default setting of 88,2 kHz or 96 kHz or 22 kHz anywhere??

    But maybe the OP didn't mean litterally half speed, but just much too slow...
