I've tried to clone a DRC impulse response into nebula.
It's a 44.1KHz 65535 samples wave file. I used NAT3 with the 3 seconds offline reverb NAT template to clone the IR. The backupthis.wav is processed in Reaper 4 64bit with Sir2 64bit. No clipping in the chain and resulting wave. And I deconvlved the processed signal into a nebula program.
The sound is different and the sampled nebula program is tilted to high frequency a bit. As shown in attachment, the frequqncy charts are aligned at the low frequency peak point.
I want to clone the IR precisely at least in frequency domain and compare them fairly. The nebula one sounds more clear and open but the frequency curve is not exactly the same.
Any idea what should I do to clone an impulse response?
I've tried it many times last month, because I wanted to create a "quasi modulating" Bricasti preset (using multiple IR's). The results always sound different from the source (less depth and often more metallic/brighter) and generate crackles/noises. You can hear it by running the Volterra test tone though your reverb preset. The noises seem to be a limitation of the playback engine.
I don't remember which template you should use for reverbs in offline mode. Trouble is that nebula tries to synchronize the main peak, so the beginning of your sample is maybe truncated, here the difference.
while nat is able to clone an impulse response perfectly, nebula sometimes can't play the correct predelay. It happens for digital linear eq emulations and sometimes digital reverbs, but you get back phase coherence. They are just few cases. A library dveloper could deactivate synchronization, but it's complicated. So if it can't be cloned, go ahead
