Bounce too many times!.... Sound Fluctuation's

Can anyone help please.

I have a Guitar Acoustic Audio recording track which I have Menu/Audio/Bounced to join together a good 6 -10 times, I am guessing.

I have noticed a sound fluctuation from the audio file when I play it back on its own, now. Is too much “Bouncing” bad for audio files.

hope that sounds the right way to describe it, or should i be using Edit/“RENDER in place” instead

thanks for any response.
