Zip/beep sound during acceleration and deceleration

Zip/beep sound during acceleration and deceleration
Hi all.
I discovered a few annoying things with my car in the past weeks. I have searched around on and off for the past two weeks and can't find anything. So, here's the deal.
1. About every fourth or fifth time I turn my car on it makes a terrible belt slip/squeal sound but it doesn't affect the driving. No SES or CEL light on.
2. The second problem and one described in the title. When I turn the car on, every time it makes these weird beep/zip sounds. I realized today that it makes this sound as soon as I push on the accelerator and then again when the rpm's go back down to idle after I have let off the gas.
Both "issues" don't affect driving at all. Serpentine belt replaced a month ago. Would love some guidance with these.
Thanks,
RC

That's a possibility. My brother's 2007 Camry had this problem, and it turned out to be a loose/weak ground in the stereo. It was more of a high pitched whirring noise that changed with the rpms. Not sure about a beep or zip sound. That's pretty befuddling.

I can make a vid tomorrow. I am going to make kind of a chart for you to see where the weird noise is.
?- stands for car start
!-stands for the beep
/- stands for acceleration
\-stands for deceleration
Here it goes.

You can see that the noise isn't while I'm accel/decel, but right at the beginning and right at the end.
I hope that makes sense.

You need to provide more details - approximate sound location, its recording otherwise it's close to impossible to guess.
I'd suggest Road Runner making circles around you .
Seriously - is it coming from inside the car or outside? Drive next to the brick /concrete wall with window down/up so you could localize it better.

I bet the two problems are related.
Did you buy a good belt or a cheapy?
A cheap belt will sometimes squeak when brand new.
Also, check your pulleys, tensioner and idler pulley for bad bearings.
Use an automotive stethoscope to find which pulley has a problem.
Be careful. You don't want an encounter with a belt or a pulley,
