Hi folks, newbie to REW here so looking for a little help from the experts.
I'm doing a a RT60 study of a church and took measurements a few days ago.
I was following the ISO 3382-1 method and allowed approx 5 seconds of pink noise through an omni speaker to get a steady state in the room for each measurement.
I recorded my measurements to Audacity as I am more used to it and I'm planning to import the impulse responses to REW.
My question is, is there a particular way to truncate and prepare the 5 seconds or so soundwave files for each measurement so that I am consistent across all my different source and microphone position files?
Or is it just a case of cutting in at the peak before the switch off decay and deleting everything before the peak? I feel like that would throw up inconsistencies.
Or if there is a more clever way to do it then I'm all ears.
Thanks in advance!
Finn
