ECM8000 : Does the job

This is useful for small/home studios on a budget that require some examination of room acoustics. I downloaded the trial version of Sonarworks and found this microphone did the job in terms of characterising my space. I could not find an official calibration curve readily available but did find one on a third party website that seemed believable. Perhaps that is a limitation to be expected on a budget (I believe some brands have a specific calibration included) but it seems more than adequate to discern any particular problem frequencies with a given room.

Although fitting several bass traps seemed to make little measurable difference in my room, this microphone was adequate for me to get to know the space for better or worse.
