mitchbakermusic Posted September 30, 2016 Share Posted September 30, 2016 So I'm neck deep in making a comparison series between Fractal and the Helix right now, and I've been bothered so much by a thought that I had to come here for a definite confirmation or denial. My question is this: Are the Helix cabinet impulses the actual microphones being placed in front of the cabinet being captured, or are the microphone models actually impulse responses of the microphones being placed upon a neutral reference microphone's impulse response of the speaker cabinet? If that phrasing doesn't make sense, I'll explain with two methods, using an SM57 as an example: Method One: The Standard. Cabinet is set up, an SM57 microphone is set up in position to capture it, impulse is taken, then the microphone is moved around and captured in various other positions/distances. Then the SM57 is changed for, say, an R121, and the whole cycle repeats itself. Method Two: The Cool, Modern, Easy Way Cabinet is set up, a neutral reference microphone (designed for completely flat frequency response) is set up in position to capture the cabinet in all the same positions as you would a normal mic. Then a impulse response of an SM57 is placed on top of the neutral impulse response to give it that flavor, and so on and so forth with other microphones' impulse responses. The reason I ask is that it is highly unusual for me to see that the AKG D12 and D112 are options for every single guitar amp, and I feel like that would be way too much effort for Line 6 to go through on microphones that are basically only used for bass amps and kick drums. It makes a lot more sense that they simply had those impulse responses to stack on top of each other, and figured they might as well include them with the guitar cabs. This was something Fractal was doing for quite some time before they started focusing more on actual microphone blends, so this is no accusation of foul play, I would just like a clear answer on this.
