when the engine weres down
With just that to go on I would say that your clutch release bearing is going bad especially if the noise quits when you put pressure on the clutch
Can be a throw out bearing in the clutch assembly going bad.
If the RPMs in the engine increases and the speed not, the clutch may be worn out, usually it becomes noise at the same time
A bad throw out bearing will make noise when the clutch pedal is pushed down.

No, I have had to replace mine numerous times, and have never had abnormal noise.
will tires make noise if there choppy on inside
the front end load bearing or other bearing in the gearbox will be stuffed. when you engage the clutch the gearbox doesnt have any drive thru it so stops turning and then you noise stops.
A throwout bearing can make a whistling sound- really more of a chirp than a whistle. Unfortunately, it sounds like you are in for a new clutch assy.
The throwout bearing is bad. the throwout attaches to the clutch fork and presses into the clutch pressure plate when clutch is depressed. You will need to replace this and complete clutch assembly. Make sure that you have the flywheel turned while clutch is removed.
What you are hearing is the clutch on the air conditioning pump engaging... the alternator doesn't make any noise unless the bearings are going bad and then a grinding noise will be heard.
That noise is coming from your throw out bearing mate, the bearing that engages the pressure plate of your clutch, many vehicles make the noise, I have seen vehicles with a knew clutch put in and it still makes the noise, id doesnt effect the performance and is too big a problem to worry about.
