I'm looking into virtual speaker emulation with headphones and the Smyth Realiser keeps popping up. I've noticed the Smyth Realiser does not let you use your own amp and dac.

Is there something similar to the Smyth Realiser that allows you to use your own set-up?

There is a software package called” Out Of Your Head” that you may want to look into. The Smyth Realiser A8 has a toslink digital output that enables you to use your own DAC and amp. The A16 has more flexibility but is not on the market yet.

I've heard the out of your head software degrades the sound.
What does the Smyth Realiser do that you cannot get elsewhere?

It creates the specific illusion (quite well BTW) that was intended. There are no claims one way or the other about anything else. It requires a training calibration process and the active head location device, without this feedback there is nothing else that can be compared to it.

Wait so, the Smyth Realiser attempts to replicate the performance characteristics of the room and the speakers it is calibrated to?
That seems like one step forward one step back to me. A speaker will rarely if ever match the performance of a top quality headphone driver next to your ear.
Is there anything like the Smyth Realiser that only emulates room acoustics and not the performance and sound characteristics of the speakers too?

Not that I've heard of. The Smyth has to have the speakers for the in ear measurement. The speaker and room are what is imitated. One could imagine a system that used non-speaker impulses - such as an electric spark, or a gunshot as the stimulus. But I've never read about such a system.

I've been trying to build one; so far no luck but I keep trying.

Do you mean you;ve been trying to build a dsp that replicates room acoustics without speaker characteristics added in?
If so add me to your short list of people interested in helping you achieve that goal.

Are you sure a gunshot or spark is sufficient to capture room acoustic parameters?
Don't room acoustics change with frequency?

An impulse like a spark or a gunshot is supposed to contain all frequencies equally. I'm not sure that they really do, but that could be measured and characterized. Both are used in acoustic measurements, but I don't know the details of the implementation.
