The audio quality produced in v2 is worse.

I agree. V1 is better

I am a historian and work with historical sound recordings; in addition to the improvements I make with various programs, V1 from Enhance Speech often had a positive effect; in some cases the voices became a little easier to understand. This is no longer noticeable with V2; even at the lowest setting, even with only 1 percent, the voices sound unnatural and become somewhat distorted with a simultaneous decrease in intelligibility. In this respect, V2 is a major disappointment for me. Just as feedback.
