I am running guitar fx processing using a 32-sample buffer without dropouts on a humble Raspberry Pi 4 with a USB audio interface using convolution for guitar cabinet impulse responses.
Oh I see. But in that case you certainly don't need such a long IR. I'd say 10ms is more than enough to completely profile a guitar cabinet. I've been probing some digital cabs with a delta function and after 100 or 200 points (@ 44.1kHz) the IR is pretty much zero.
