ROOM SIMULATION- RIGHT SUB MEASUREMENT DISCREPANCES My fault - I didn't notice that the sub was pointing in the wrong direction. Sorry. Chips Davis

ROOM SIMULATION- RIGHT SUB MEASUREMENT DISCREPANCES The "Y" distance for the right sub is not correct. the left and right speakers show the same measurements. Chips Davis

Do you think you will implement NIC measurements? Chips Davis chips@chips-davis.com

You assumed that all of the microphones are the same. I have 2 ACO Pacifico mics and 2 B&K 4006 mics. Their sensitivities are different, The last mic calibrated, sets the calibration for all the inputs. Chips Davis

If using multi mics in a larger area or large hall, there can be a difference between the levels that each mic is receiving, i.e., when averaging the spectrums, the weighting of each mic’s contribution may be major or minimal. If there is ten dB difference between mics, that mic will have very...

Will you implement STI on the Pro version? It would make REW far the most complete of all the measurement systems. The only area that I have found STI measurements less accurate is low frequencies can mask the perceived intelligibility, that is not taken into account with the STI measurement...

Confusion on calibration with a B&K calibrator. Chips

The Leq weighting doesn't seem to be working. n switching from "Z" to "A" after resetting doesn't change the levels. Thank you. Chips Davis

Oh, if anyone would like a link to my ASA paper I could post the link. Chips

Sorry this has taken me some time to replay. "Realitive Time". I'm glad that I have the time to get more into REW and learn more of the great program you have produced. Relative time and 0 time- Zero time is the time starting with the referenced output from the generator. That time includes the...

Many years ago I asked Richard Heyser to implement "Relative Time" into TDS (Time Delay Spectrometry). This gives the ability with an ETC (Energy Time Curve) to figure out time (distances) from the direct, any reflection, or accumulative energy events or energy returns. By blocking the mic from...
