That's what I think. This week I have more measurements in another venue. So it will be determined if the artifacts are depending on my measurement system or venue specific. Thanks a lot for your help!

Alright! Thats possible. These were my first measurements with rew, and therefore thinkable ;) But this does not explain the peaks in the high frequencies, right?

Ah great Idea! Thanks! I think, the spectrum of this artifacts is between 6 and 12kHz. The remaining frequency components seem to be rather background noise and parts of the reverberation time of the main impulse, cause the level of the spectrum is 50dB below the Q1 courve.

Hm interesting. How did you separate the impulse response to view the frequency response of the second IR? For me it seems like a artifact of distortion. I have read some articles today and an sub harmonic distortion may looks like the same and is positioned in the positive time of the IR. If...

Unfortunately I only kept the 2M measurements, because the second "impulse" was within the usable range for the shorter sweeps. Attach you will find 3 measurements. 3 different speaker / speaker positions at the same mic position in the room as in the drawing.

Hi there. I have a few questions about my measured impulse response. Has anybody already seen impulses similar to the one in the picture below? The second pulse at 1.8 seconds changes with different sweep lengths. Thus the error is not time invariant and therefore not an artifact of the measured...
