distortion

Hi wonderful AV reader! I would love your help to figure out what is happening with my brand new car's speakers. I believe something is wrong with the fancy 21-speaker audio system in the 2024 (not previous years) Lexus RX 350h and TX (and other models) and I need YOUR help to prove it. ASK...

Hi, Is there any way to somehow set the control limit for distortion graphs(ex. 5th Harmonics). I mean something like that(Lower Control Limit, Upper Control Limit): So the user can visually see the limits corridor and make decision, is distortion in the limits or not. One idea was to export...

Hello John, First of all thank you for making REW and all that it makes possible. I am currently using REW for distortion measurements of a DIY 100W power amplifier, with the usual idea to make it as quiet and distortion less as possible. Currently I am measuring around 0.00015% distortion...

I've read about a few methods to calculate THD based of IEC or IEEE. Is REW calculating THD relative to the fundamental only or fundamental + harmonics?

Hello, I am quite a newbie using REW and I am trying to understand why the curve shown in distortion feature after performing a sweep measurement does not match the values displayed in the table below? This is happening for THD. As a bit of background, I am using REW to measure the response of...

In Generator the output at -3dBFS of Pink Noise (Full range) is too high and there is a great distortion/overdrive. Has anyone encountered this problem? REW 5.18 Windows 10

I noticed that the SPL level in the SPL window and in the Distortion window are not alike. The SPL window shows higher dB values - 10dB or more - than the fundamental in the Distortion window. What is going on? Thanks in advance!
