This application simulates the acoustics of a room and reproduces the sound signals for the two ears of a virtual listener inside the room. Listening to these signals using headphones gives the impression of being inside the room at the position of the listener. The positions of the sound sources and the listener can be modified in realtime.

I was caught off guard when I put my headphones on and used the app. Never thought an app could reproduce real life sound like this does. Take 5 minutes to try it and you will be like me showing your friends the app and see the reaction.

What this app offers: The Virtual experience to hear sounds as if you are in the room. Ok, perhaps there's no much use for this other than that, but I can see this technology productively used for other projects. What I got: AMAZING experience. Using the headphones, not only do you feel you are in the room, but it sounds as if the sound is literally coming from the corner of the room, or wherever you place the four speakers. I always wondered how, while listening to music in headphones, different instruments seemed to come from different positions. Perhaps they use something similar to this to test it out and make those virtual effects? My conclusion: This app is free and it does what it says. I think the experience it offers is more than worth it, specially for audiophiles (sorry spelling may be wrong). I would love an app like this, with the addition that I could create virtual sounds or music, even if just for relaxation.

I don't usually leave reviews, but I felt it necessary in this case.
This is an amazing, well made app that really does give you the sense of the directional acoustics of being in a room with regards to its sound samples. Remember to use headphones.
Very impressed.
Hope to see more by the creator.
Well done.
