Ultrasonic: Newbie Question

[Rust]

Hello, I do apologize if this is a stupid question but this is bothering me for some reason.

I'm listening to MLS 3.0, specifically the US format. This is my first time using this format. I seem to be able to hear the US sound. It's really hard to describe. Because of this, I've noticed that there are a few instances during listening where the US sound "drops" for a few minutes and I can hear nothing. I've also noticed this while using the Hybrid format - there were instances when I could only hear the masked part for a few minutes, then the US would "kick in" again.

My question is - is this normal? Just making sure the sub is working the way it's supposed to

That's ASRB: Audio to Silence Ratio Balancer. It gives your brain a short rest to help prevent overload on the input, decode and execute channels during input. This allows it to clear any queue of input that has built up while listening, and also begin executing. The result is that you will experience less mental load (prevent exhaustion) and achieve noticeable results faster. So yes, it's designed in.

Understood. Thank you!
