Been messing a lot with Impulse Responses using a load box of late and I definitely have my own leanings, so I thought let me test out some of the stuff you hear regarding impulse response quality, such as there is no difference between 200 and 500, high quality and low quality, etc. Here are a couple of tracks. One uses 200 ms impulses, the other uses 500ms impulses. I am attaching the tracks as wav files from dropbox because Soundcloud really compresses the tracks and makes them sound exactly the same. https://www.dropbox.com/sh/ep36taa0grp3os4/AADRkwbXUq0ikGCBiP6qbMNGa?dl=0 In each track, I go through the various quality modes offered in the Nadir loader - Low, Normal, High and Extreme. Methodology: Have set my amp settings to taste, then set up my reactive load and IR loader. I play some single note stuff in each of the quality settings and then some power chords in the same way. Both the single notes and power chords are double tracked with the idea that it would be easier to tell the difference between the various settings. Anyone want to guess which track is 200ms and which is 500ms? Also, anyone want to take a guess at the quality setting of the IR loader (the same order on both tracks). Better to listen with monitors, there's definitely a difference. Louder is better for making that out. You may be able to tell the difference better with the chords than the single note stuff, just skip to the 58-second mark. I apologise for all sloppy playing. There's no noise gate on there as well. I'll post the answers about which track is which and the order of the quality settings later.
