Compression tends to discard high-frequency signals since they use the most bits.
If you slightly alter the low frequency signals, they will be preserved. 30.1 Hz -> 30.2 Hz.

Quite certain that’s not true. We drop everything pass 20khz simply because it’s outside the average person’s hearing range.
We drop everything under 20hz too - we also cannot hear below that.
