Weird sound/squeaking
 

Its been a while since this has occured but never put much attention to it
i have heard my squeak n squeak i thought it was the belts and ive told myself imma tighten it up (i replaced the underdrive pulley with the Agency Power Pulley) but tonight i pressed on the clutch pedal and the squeaking stopped and i kept doing it pushing n releasing the clutch pedal it would stop n resume then i drove with the windows down n when im driving it still squeaks and when im accelerating pass 6-7k rpm i hear a weird sound coming from inside the car. my question is what can it be? is it time for my clutch to be replaced? and something else one day n only occured that day, i pressed the clutch pedal in n held it n would start making a high pitched whine. Anything would help
Thank you- Carlos
