IF it's not chain rubbing FD/twisted der., then remove the crank.. check for a trashed bearing. Could be pedal noise too.. the left side.
it sounds like a caged bearing that's on it's last leg... and i don't care how old the BB or pedal is.
the noise is more when you down-stroke on the left side.

T47... press fit, or threaded version?

SOME treks, and a few others, have had ugly noises from a PF BB walking around in the frames....look for powdery or dark gray buildup near the BB

once again.. check the left side more intensely.

another possible... big ring's teeth hitting the der, cage. Check yer clearance, Clarence. Left downstroke will rock the crank up on the right side......... proper is 2-3mm.. less than one is never fun.
