it's the PWG engines on a320 family, a220 or embraer e2, it has the distinctive "whale" howl produced at low engine N1 due to acoustic resonance of that particular geared engine

Leading edge flaps changing airflow into the engine, makes a howling sound.

The Leap 1A (GE/CFM) or PW 1100G engines on the NEO variant of the A320 family makes noises like this due to their combustors

PW Engine spooling for some airbus A320/321 NEOs and also can hear it from the a220.
