 Has REW changed since this thread started? My version of REW does have an SPL meter, or am I way off-base with this somehow.
Also, when running a .cal file on the ECM8000, do you then get accurate measurements up to 20kHz or is this mic just not good for measurements that high? |
Hi Dave,
REW does have an SPL meter, but you have to calibrate it by using an external SPL meter. The "meter" in REW doesn't know what it's seeing unless you tell it a relative value, which comes from the RS meter.
As to measurements up to 20 kHz, I'm not sure about the mic's response itself. However, room reflections and such make it difficult to measure that high. I think you'll get a pretty raggedy response even if you had the best and most-accurate mic in the world.
