My producing mentor Alex at Audio Edge sent me here. If you are serious about producing and mixing, you should definitely get this software and the reference microphone. I started out with a trial period of the plugin to my DAW, and honestly didn't think that it would make much of a difference for my headphones. I was blown away by how much my (then) untrained ears could hear the difference in sound! After having worked with headphones only I bought a pair of Yamaha HS5 speakers and I have also treated my walls, floor and ceiling with diffusors, bass traps, clouds, carpets and absorptive panels. Then I bought the measurement microphone and did the Sound ID Reference Measure. The result was very interesting. My room has a tilted ceiling and is asymmetrical. The measurement mic picked up on all the peaks and attenuations in my studio environment and the software is now adjusting the output levels. I would have been totally unaware of the many differences in frequency responses between the left and the right side of my room for instance. The software compensates for that now, and that flat curve sound makes my mix able to transfer to all kinds of speakers. I love that there are many translation alternatives you can choose in the software to compare your mix with: 3 cars, 3 laptops, 8 ear phones and some other stuff. I use a mac and FL Studio. The only downside I can think of is that you always have to remember to manually turn off the plugin before bouncing something out. CONCLUSION: It doesn't matter how great your speakers or headphones are, or how much you have treated your studio. You will still not have a clue what your mix really sounds like! So yeah, you need this software to be ahead of the game.
