*RESOLVED* - Help! How to Record Audio tracks "free form"

Hi

I am Fairly N00b here so please bear with me!

I have imported an .aiff 44.1 24 bit audio file that was not recorded against a click so the tempo fluctuates all over.
My project is 44.1 24 bit
I am trying to record acoustic drums against the "free form" imported track but as soon as I play back the tracks, what I recorded is not in sync with the free form audio. what I record doesn't even line up with the "CLOSE" metronome tempo I am using. This is driving me nuts, I cant figure out how to just record Free form and have it line up.

I have searched here for days and can't find the answer...maybe I am using the correct terminology?
Please help if you can.

Thanks!

-Pete

    Free wheeling recording is what made up 100% of all recording up until somewhere in the 80's. Even then most real bands will record live and without the crutch of a metronome.
    So 3 things can cause bad timing
    1-The musicians
    2-The recording gear is not syncing up properly.
    3- Monitoring has a delay in it.
    Sorry can't help you with your timing as a musician but you can test Sonars accuracy by outputting a transient track like a snare and routing it back and re-record it. Zoom in and check that the transients line up.
    Sonar is set to automatically compensate for your equipments latency. There is a manual offset you can adjust if this is out.

    Other possibility  is you have your monitoring set up wrong and you are hearing the latency of your system so your playing to the out of sync track. Test your overall round trip latency with this free tool from Centrance

    What you probably want to do is...

    • Set your metronome tempo to match up fairly well with the first measure or so of your song.
    • Turn on "Audio Transients" for your reference track in the track's edit filter.
    • Drag your reference audio track so that the first recognizable beat one of the audio track matches up with a beat one on the SONAR timeline.
    • Use the tab key to move to beat one of the next measure.
    • Use "Set Measure/Beat at Now" (Shft-N) to set the tempo map so that the beat will land at this position.
    • Keep doing this through the length of your track.  If your tempo is fairly consistent, you'll only need to adjust the beat at every measure or so.  If it's truly rubato, you may have to do this for every beat.
    • You'll probably want to have the Tempo view open so you can see how your tempo changes look over time.
    At the end of this (if you've done it right), you should be able to play your track back with the metronome on and have the metronome track the free form audio pretty closely.  At this point, you can MIDI drum to your heart's content.  (Oops!  You wanted acoustic drums.  Never the less, having a metronome that tracks well will help your drummer out too.)

    I think there's an automated way to do this, but I only tried it once and didn't get instant good results...and didn't have the courage to try it again.

    -  Set your computer/ Sonar up properly
    -  Hit Record

    Thanks for the answers guys,

    Although his answer was flip, cactus was right. I had forgotten to disable my on-board audio card. Running perfectly now with just the Firepod. Found the answer here in another post.

    Dan thanks for your response, I will use your procedure when I need to quantize an audio file.

    Regards,

    -Pete

    Happy you got what you needed.

    By the way...the procedure I mentioned isn't for "quantizing" audio.  It leaves the audio alone, but gives you a tempo map that matches up with your existing audio so your barlines match up.  If you're recording all straight audio, it isn't that big of a deal.  It becomes a lot more useful when you're supplementing your stuff with MIDI or tempo based loops.
