![]() I was thinking you could make an ir of a reverb with out chorus, then apply a subtle chorus on after, if you want you could even in Protools audiosuite a chorus effect onto the audio. I'm guessing if your sampling left and right separately with chorus on, the recorded result would be left and right with 2 different choruses not in sync with each other. And from what I understand if you want to sample these units you need to turn it off due to potential phasing issues. True allot of these hardware units have a chorus effect inbuilt. You could even use a bell sample and load that as an IR and then run a signal into that to create something unusual.Ī sine wave sweep seems to be most used as it covers a wide frequency range, in turn capturing more characteristics of the reverb. If there is only one value all is good, if there are some extra values by interpolation delete those so you are left with the highest value only (one value)įrom what I gather the possibilities of what one can do with an IR is vast. txt in adobe and then open it in a text file. One other way to have a perfect dirac is to save the audio as. You can make your own though in any editor like Adobe Audition by zooming in to sample level and pulling one sample to the top. There was a place on the net where you could download some Dirac spikes but i can't remember where. If the EQ or sound changes in any way then you need to move the spike sample forward or back. If you see that raising the wet signal simply makes the volume louder it means the spike is in sync. One way i have found of testing if the spike is in perfect sync with the audio (because if it is a sample before or after then you will have phasing issued) is to play the spike on its own through SIR. What you do is you play the spike (the single "perfect" click) through your hardware and what you get is essentially the reverb at that point. It is perhaps not the best way to make an impulse, but for a simple and efficient result i think it works very well. I've had some great results by using a dirac spike ( a single sample in an audio editor at full volume ) and capturing some of the reverbs in Adobe Audition. Once extracted your left with a channel of reverb decay etc.Īnyway I apologise If I opened up a can of worms but I'm sure that there are some talented people here that dabble in IR land and I would be very grateful if someone could give me a few tips. Once that is done the sine sweep needs to be extracted (I think? ). running a sine sweep into a channel of the reverb unit then recording the end result. Just to note I generally understand the principle i.e. (3) I did some research, if you are sampling a Lexicon you need to turn off the chorusing effect? is this correct? (2) are there any other useful Mac compatible software packages that is better than Apples IR utility - or that have some other helpful purpose. (1) is Apples IR utility only good for space designer or can it be used for other reverb packages? I'm guessing you might be able to deconvolve the recorded audio and export it as a Wav? I'm a logic user so I have access to Apples IR utility. I would like to make an IR that would be cross compatible in say Waves IR, Altiverb and Space Designer. These are just for my use, and thought it would be an interesting challenge to investigate the process a little bit. ![]() I was hoping some kind person, could give me a couple of tips.įirstly I'll explain what I'm trying to do, I'm hoping to make some IR responses of an external reverb unit such as the top of the range lexicon 960L.
