how to change frame rate of n aoudio tracK?

in the last 3 months i was working on a video editing.
on a live preformance.
this proeformance was shor from five diffrent cameras.
(i dont know the what models those cameras were)

and and the aoudio im using
was recorded

with an aoudio recorder (TASCAM DR-40 4-Track Portable Digital Recorder)

its all went pretty well.
except for one thing
the sound from the aoudio is slowly drifts out of sync.

after searching the internent
i now belive its a frame rate.
issue.
so if anyone any here have any idear of how to change frame rates.
of a an aoudio track. i will be happy to know about it :)
