Cheap Calibrated Microphone
Posted: April 17th, 2014, 5:05 pm
Information for anyone in the group, not in possession of an audio measurement suite.
I just bought a $70 USB microphone from Parts Express. Once receiving the microphone, one enters the serial number on line and receives the calibration sheet for the individual mike you have. The mike is intended for high SPL readings and at under 57dB, the readings are not reliable.
One user posted his calibration chart in a brief review. I thought it was all over the place until I noticed that the major vertical divisions were 0.5dB
Combined with a PC and free software "MathAudio Room EQ component for Foobar2000" one has a room measurement suite, at least a simple one. Better than nothing by a whole bunch.
The mike,

gets almost 5 stars; the big downside being the 5/16" mounting hardware, not the standard 1/4" that fits standard tripods.
I hope this is of some help. If it's beneath your dignity to own one, please don't flame me.
