Thank you!!! Honestly, I've used both and had good results. Cardioid allows for a bit more spatial isolation if you're shooting for a 5.1 reverb with a clear "forward" direction.
@@devinlsheets_alphasound I'm curious because I use impulses for placing dry sounds in the environment and improving dialog recorded in the studio (for games mostly). I'm torn between using omnis which should get more of the room response, and mics actually used for recording things like that - hyper and supercardioids. I know I should just do my own tests but I figured somebody must have did this already. Somehow, your video is one of the very few good resources on IR's I could find (outside of recording guitar cabs), so thanks for that. I didn't know the trick with trimming of the impulse.
Thank you... this is refreshing info about what I've been interested in & looking for... I'm sick of only being able to find guitar cabinet speaker & guitar amp IR videos when I use search terms like IR, impulse response, convolution reverb..., that stuff is still interesting, but its hard to find videos like yours where people are making/demonstrating real acoustic spaces, so thank you!! ...side note...like I said, the speaker impulse response stuff is equally cool & interesting in it's own right... I just wish more people showed or played with other types of speakers like bullhorns/megaphones/PA horns, the small speakers in old computers & old electronic toys & radios, etc. (like Plogue's chipcrusher)... loved your video & thanks again!!!
Oh, that's so cool, I never knew. Especially the idea at the end, could this be used to help with the classic mixing problem of thinking ah yes perfection during practice, followed by the frantic effort to get it back to where you like it during the first song?
...or you could take the impulse response of the sound system in the concert hall and do complex division to create an 'inverse' impulse response that cancels out the reverb of the room. I did this with a fax machine speaker, however you lose about 24 dB of amplifier power.
How loud should the speaker outputting the sine wave sweep be when capturing an IR; as loud as possible without distorting the speaker, or just loud enough to excite the space?
