I realize it wouldn't be possible to put the Smyth mikes and IEMs in at the same time, but wouldn't it be possible to create a mold of one's ear canal with one of the DIY CIEM mold kits and make a replica of your canal (with materials that are similarly absorptive to the tissues in the ear) and create a PRIR suitable for IEMs?
I know it probably wouldn't be easy, but depending on the materials needed for the replica, you might even be able to find someone with a 3D printer to make them... Anyway, if this is a crazy idea, let me know and I'll go back to wearing my tinfoil hat and muttering to myself.
Actually, I think the "Smyth Realiser READY FOR PURCHASE" thread is the proper place to ask this question.
Also, I don't use IEM's so I'm not really qualified to answer from firsthand knowledge or experience. But I believe that when using IEM's to listen you do not need to use an HPEQ file, which is the second file utilized by the Realiser when listening through external over-ear headphones. The HPEQ is only required when listening through external over-ear headphones, and is created by having the microphones inserted in your ears and then putting your headphones on, over your ears with the microphones still inserted. That "measurement" process produces the HPEQ (corresponding to a specific external over-ear headphone/amp and your own ears).
The listening environment itself is "measured" through microphones inserted in the ears WITHOUT HEADPHONES OR IEM'S INSERTED, and produces a PRIR file, which is the first file utilized by the Realiser to duplicate that listening environment for playback/listening through a Realiser preset. To complete the playback/listening preset an HPEQ is selected if using external headphones, or no HPEQ if using IEM's (i.e. only the PRIR is needed when using IEM's).
In other words, the PRIR required for playback/listening is required for any type of listening... either using over-ear headphones or IEM's. And the creation of that PRIR is done simply with microphones inserted in your ears.
The HPEQ required for playback/listening is only for over-ear headphones, but is not required when using IEM's. So there is no issue such as the one your are concerned with if you're going to be listening through IEM's, as the preset only consists of a selected PRIR.
