Time stretching a string quartet recording

I’m waiting to get final audio tracks from a string quartet. From listening to the roughs I realize that the final movement, at 138 bpm, would be better at around 144 bpm. There is a middle section, surrounded by an eighth note rest on each side, which could stay at the recorded tempo. Bumping up to the desired tempo would be about 4% of a difference. Can I get away with that much of a shift without compromising the audio quality?

Hi!

Yes it’s possible but use the best algos in Dirac
it’s what WaveLab is using for time stretching
but even try other DAW apps to get the best sounding results
like Reaper, Cubase/Nuendo, Audacity etc
I’m sure there is some other ME in here that got good ideas for this!
