When creating a PRIR in a non acoustically treated room, do you find that you get an exaggerated, tinny reverb effect?
I'm about to book some expensive time in a high quality listening room and just want to check that I'm not doing anything wrong, and that there's nothing wrong with my equipment.
I would agree with this observation. I might describe it as "hollow, echo" sounding.
The PRIR I got at the Egyptian Theater in Hollywood (Lorr had made special arrangements) a few years back is notoriously "echoic". We were sitting first row balcony in a large empty theater, and listening to anything through that PRIR is certainly unpleasant. The original sample PRIR I got at the Smyth offices in Camarillo back in 2009, in their untreated demo room, was also very "hollow" sounding. Even the same with the Mi Casa PRIR I got back in 2009.
That's why the PRIR I got from AIX back in 2009 is so stunning. Their studio room walls and ceiling is covered with acoustic padding. Treated all around and it sounds "dead silent" except for the signal coming from the 5.1 speakers. PERFECT for Realiser PRIR and subsequent headphone listening! The PRIR from AIX is amazing.
