Question About Impulse Responses

[andres6505]

Hey everyone I’ve got a kind of weird question about IRs and IR loaders, and I was hoping someone could help me understand this better.

So here’s the thing: most IR loaders have the MPT (Minimum Phase Transformation) feature enabled by default. In many of them, you can’t even turn it off. The only ones I’ve seen where you can actually change it are Genome (where the difference is huge) and CabLab (where the change is not that noticeable).

So my question is: if an IR already has MPT applied, does it make sense to load it into an IR loader with MPT still enabled? Or should I disable MPT in the loader in that case?

I’m asking because in Genome the difference is massive: with MPT turned off, the IR sounds like it has way more range, it’s less harsh, with more low and high end, and overall it feels more open. The change is too big to just ignore.

Does anyone have more technical info about this?
What do you guys think? How do you usually handle this in practice?

Thanks in advance!

Cab Lab has an option to apply MPT on export no? Not on load? I'm not sure what it does on load actually.

I'm not familiar with Genome.

I personally don't use MPT.

If the IR has already been processed with MPT, then it shouldn't make a huge difference if its MPT'ed again but yeah why do it again?

forgot to mention that this also applies to RAW IRs.
