Disscussion| Higher rate for the cab models

Hi there!
So all of us knowing the Strymon Iridium and its controversial size amp modeler that any second session player fell in love with!

Strymon is fully proud by being the first amp modeler to support 96khz and 500ms Irs and cabs while the AX3 is supporting 48Khz only abd saying that it makes that unit to feel the most realistic and feel more like an amp in the room and other big marketing words.

But. What it actually means? Does actually larger sample rate will make something better?
Does all these big words worth it?
And does it will be possible in the future that the AX3 will be capable loading 96Khz cabinets IRs and check out what will be the result?

Doesn't apply to IR resolution, but below is a good educational video on high sampling rates vs. oversampling and why/when sometimes one is better. They conclude that a 48 KHz sample rate plus oversampling is a good tradeoff with minimal (aliasing) artifacts. (From @DLC86's post)

For modeling a guitar cabinet, the smaller bin size you get for a higher sample rate isn't worthwhile. Capturing 500ms almost always leads to undesirable smearing as the echoes interfere with the desirable response in the frequency domain.

Here's the real issue: A guitar cabinet IR effect is a commodity. Assuming it's implemented properly, it will sound just like the other commercial quality guitar cab IR player effects. If it sounds different, that's usually bad. So, there's very little room to carve out a unique slice in the marketplace when the most you can claim is "we sound like all the other ones". You can try to achieve better performance while sounding the same, but the opportunities there are limited as well. In that situation, vendors will often resort to marketing hype as a way to set themselves apart.

Which is a "better" digital camera, a 15 megapixel or a 25 megapixel? All else equal, which will give you better picture quality on your PC monitor?

Same picture quality, unless you have an 8K monitor.

And you can't zoom in on an IR.

FYI the Iridium runs stereo 500ms IRs. The 256ms IR they talk about is part of their IR/algo-hybrid room reverb.

Corrected. There is no way anything useful for a cabinet IR happens after 100 ms or so. For a DTFT yes, but Cabinet IR no.

And the benefits of 96KHz when recording should't be confused with using 96KHz to capture an IR.
