Noise when accelerating hard

:
2003 Mazda Protege5
Hey guys, my P5 has always mad a noise whenever i fully depress the gas pedal quickly. The sound is most audible when i change gears then rev match under heavy acceleration.

I cant really get a clip of the sound as it isnt super loud and i dont know where it is quite coming from. My guess would be throttle body or the gas pedal itself?!

The best description i have for the sound is it kinda sounds like it could be a valve of some sort squeaking, but it does sound like a squeak of some sort, slightly like a BOV but not haha.
 
Its no decceleration im just using the wrong term. Its when i change gears whilr accelerating. So it makes the noise when i put my foot back on the gas when bringing the rpms up to the next gear
