REW

Most powerful tool that every audiophile MUST have (within the UMIK microphone). Sometimes people are spending thousands on their audio cables and other snake oil things but cannot accept the simple fact, that one of the most important (if not the most important of them all) factors in the sound reproduction is the room acoustics. This tool for sure will help you to form the sound you want from your audio system.

Honestly, to know all the possibilities of this software one must have a profound knowledge about audio things. It is certainly not for beginners if you want to dive deeply into this world but luckily - the most important things are easy even for the beginners like me, particullary the room acoustics simulator. When i did measured what was shown in the simulator i was blown away by the accuracy it has, it is simply mind bending, like a magic trick you see but cannot understand how it's done.

Only later comes the understanding that all the sounds from the speakers interacts directly with the room and all we hear is under the physics laws, there is no magic at all. Creators of the REW software has cracked these laws by their knowledge and they give us a most amazing, most profound and most useful tool in the audio world for free! I don't know another tool like this even for money. Thank you!
