how to correct the speed flutter recorded from an analog tape?

hi there,
 
i have an old 4 track tape deck on which i recorded a few songs many years ago.
now i want to record the tracks to sonar and mix / edit the again.
the songs were recorded in unchanged speed for example 110 bpm.
 
i open the tracks in sonar project with the same bpm and pull the first bass drum on sonars beat - but after a few beats the bass drum will be slightly before (or after) the beat.
i guess this is the result of the tapedeck not running at a constamnt speed.
 
since i would like to edit the tracks with tempo based fx i is necessary to fit the track exactly into sonars bpm measures.
is there a easy way to do so? maybe with various tracks simultaniously?
 
thanks in advance,
 
cheers
 
chris

    if you have melodyne 4 I think you can extract the tempo from the audio track.  I haven't done this before so wouldn't be able to guide you through the process but others might.  I'm not sure whether the version of melodyne that comes with Sonar will do, or whether you'd need to upgrade.

    Google "site:forum.cakewalk.com Set Measure/Beat at Now" Brundlefly has posted several times on how to create a tempo map from an audio track using that (can also Google similar to above for "Shift-M")

    if you copied all 4 tracks from the tape at the same time, then maybe there is some audiosnap or other quantinization going on? otherwise they should all be in sync with each. if you recorded each track separately, then you might have a timing issue (so i always just copy all tracks at the same time...)
