Here is one response file and a photo of my setup.

This plot is of a single speaker and I'm testing outdoors. The speaker is about 1m above the floor and the nearest obstructions are about 5m away. There are two items in the attached plot I'm concerned about. The first is the continuous signal that has a 1.25% peak, is this noise and...

One last related question before I burn the CD. Under Generator, the default RMS Level dBFS is -20. Does this need to be changed to -12 to match the Level dBFS that is listed along with the frequency on the Log Sweep and other waveform selection or under the Measure, which also has -12 dBFS or...

I think I'm missing something here, is it because I'm using v5.18? Under Generator, I understand I can make a .wav of PN to set the level. I can also make a log sweep .wav, but there is no option there to insert a timing reference. Also, the log sweep .wav created by Generator is 10s long and...

A bit more research. The PN file would be used with the SPL meter to set the proper volume at 75dB. I would then play the logarithmic sine wave sweep. Under "Measure", click start measuring when this file is playing and then stop measuring when done?

I have the UMIK-1 and have already taken some speaker measurements using the basic tutorials, I got this primarily for home speaker assessment and speaker building. But I would also like to fool around with in-car measurements. I have several different car speaker systems I would like to...
