If you haven't already, read this: http://designingsound.org/2012/12/recording-impulse-responses/ Some great info in there. I don't actually use TL Space, but I believe you can load impulses into TL Space in .Wav format? At least that's what it says in the manual. OSX has the impulse response utility built into it - have a look in Applications/Utilities ...

I agree with Internet Human's approach, I think physical baffling is the way to go. I have found success in the past by actually using the floor of my previous house. I needed to record footsteps (and a fight) from above, so I set up 4 mics in the basement facing upwards about a foot below the ceiling, and then I had fun running around upstairs, slamming my ...

Theoretically, the "bang" is suppose to produce a perfectly instantaneous amplitude peak. If you convolve a signal with your full impulse response, you will get the original signal mixed with its reverb in the recorded space, which is what is expected usually. But you can experiment with fading a very small part of the beginning of your impulse response and ...

Recording 4 impulse responses for 2 playback channels is confusing. You could easy use a 2 channel impulse response to create a 2 channel playback signal. If you get a more detailed look, you will realize that you have with a 2 channel IR 'only' signal from hard left and hard right. But in a mix, you have signal from right which goes to the left channel an ...

From my experience as a vinyl cutting engineer, the phase response makes it look more triangular in shape, but it sounds very similar.

Thing is that such a signal only exist in theory - practically this signal will be made up of a number of sine waves with varying frequency and amplitude. The generator or the sample rate format determines the upper frequency limit (i.e. how "sharp" that seemingly discontinuous signal edge will be a the corner/peaks). This alone will transform your step ...

Guys who master vinyl will tell you something like this: - A pure step signal has an infinite spectrum and, considering you can't hear above 20kHz (a lot less as you get older) there's no point doing what you suggest. You may then say "oh please do it" and the vinyl mastering guy might say "OK we'll give it a go" and then completely ignore your request ...

I'm not familiar with reverb specifically, but from my general knowledge of signal processing, since you haven't gotten an answer already: I expect that “LR” and “RL” are “the sound of an impulse emitted at the left position and heard at the right position” and “the sound of an impulse emitted at the right position and heard at the left position” — which is ...

an impulse response perfectly describes how an impulse behaves in a room. if you know how an impulse behaves in a room you can accurately describe the behavioral of any sound in that space, using a technique called convolution. http://www.audioease.com/Pages/Altiverb/sampling.php this is a really great video for explaining the basics. the main purpose of ...

Yes, the choice of speaker will definitely have an impact on the resulting IR. You can think of your speaker as a filter in the signal chain; all irregularities in the frequency response of the speaker will be present in the final IR as well. Distortion will complicate the matter even more. That's why Altiverb has different import settings depending on what ...

Well at least there is a very short delay on it with a high feedback into the original signal. This makes the voice get so "metallic box" sounding. It's dead simple actually. Experiment from that point onwards, have fun!
