So, I played tourist the other day, and visited some local spots with my girlfriend, kind of a "rainy day" thing... At one point, we visited Severance Hall in Cleveland, the home of The Cleveland Orchestra: Being in this very old, beautiful - and fantastic sounding concert hall, got me to thinking about how I might go about creating my own reverberation impulse files; files that I could load into any standard/accepted convolution shell.. (Pristine Space, Samplitude Room Sim, LiquidSonics, SARM's Altiverb, etc.) A little research has shown me that while many of these files start (and end) solely as code - as mathematical Equations alone - that the source of quite a few of the other popular existing reverb impulse files are sourced in actual real time recording of reverberation. Often, a starter pistol is used to create the reflection, and occasionally, claps and even vocal shouts. So... is it possible ?.... meaning if I could get permission to set up some microphones in a place like Severance Hall, and create several different impulse files, as .wav files? Does anyone know what the followup steps would be to create an impulse file that is 'playable" on any standard reverb convolution program? How would I go about the mathematical recreation of the reverb so that I could "replicate" the sonic character of a particular space? Is there an industry accepted editing program for this calculation? If I can figure out how to do this, I'd be more than happy to share these files with those here who use convolution reverb as part of their mixing technique. Or, do you think that this is this too difficult to do? Thoughts? d.
