For real spaces you need either loud bursts of noise as you need both power and full spectrum to capture the room’s full response.

Impulse signals are excellent for capturing hardware processors or software plugins, but they cannot provide the power needed for actual rooms capture.

Pro tip: Don’t use dithering on the exports, for impulse responses it will mess with the fidelity of your final if you are referring to an impulse signal as the “click” in your recommendation above, I disagree that it would make for a good sharp sound as an exciter in this case, because mentions that he wants to capture the response of an actual space. In FMOD, as the convolver doesn’t support resampling of the impulses to the project’s rate, you should decide early on for the sampling rate of your final project and use that sampling rate for the exporting of your impulses. Anything around 44.KHz /16bit would be good.

I also added enough silence to make the samples 1 sec long, as some DAWs or editors have issues with files that have a duration of only one sample.įor games as suggests, it’s better to optimized your exported impulse file.

One is 32 bit floating point, and because I don’t know which DAW/editor you use I also made one at 24 bit. Here, I made two impulse files for you: !AoFZ1MP3ewRggeVrcTRCVG3LmC2ceg?e=KmhFCG This will also allow for your exported impulse responses to have a 1.0 factor as their 1st multiplication layer in the convolution process, which sometimes works nice in convolvers used as inserts (instead of auxiliary sends) with 100% wet settings. If you want to export the impulse response to a native wave file to use in other software (like FMOD), instead of adding a clap on your DAW, try adding an impulse, which is only one sample with full volume. The tiny-fication you also report might be that the added clap adds to the gain and the convolver has to normalize even more to achieve its layering, so the volume goes lower than expected. So the convolver in FMOD works ok, but your sound is in fact (and you describe it perfectly) metallic or harsh. That later is used in the process of convolution, that simply multiplies each sample from your sound stream with all the sample from the (deconvolved) impulse response, layering all multiplications by adding them as many buffers in time, and that produces your acoustic simulation output.īy adding an extra exciter (the extra clap in your case), you actually undo the deconvolving that you done in the first place, to remove the sweep signal exciter. You can use a sweep signal or a clap (balloon pop, runner’s start guns, film clapperboards) signals to excite the air inside a space, to get the space’s response, and then you deconvolve it, which means that you remove the signal that you used as exciter and you are left only with the space’s response. Hi I understood correctly you are rendering your deconvolved impulse response with a clap sound and exporting that as an impulse response?
