Hi @falkTX, this is great, however IR loaders are one thing and profilers are a different. A profiler like the Kemper uses a different technique to capture the amp tone so that it can “reproduce” also the harmonic distortion. Is a patent-pending solution unfortunately. Recording a simple impulse response of a non linear device is non-sense since the convolvers only work with “space” or phase delays -> result is sort of equalization with some artifacts. I see some IRs taken from devices such as channel strips or tape machines, well from what I know of the theory behind convolution they’re non-sense stuff. Warning: I am not saying they couldn’t sound “good” I am telling that they’re not achieving their initial intention, to capture the tone of the device. May propose a different direction? With a different technique instead? Profilation is somewhat an outdated story already since “the guys” now want neural techniques applied to amp simulations (hell ya!). It was mostly an obscure thing for me since I discover this. What do you think? Is there anyone interested in this?
