Just circling back to on this. It turns out, most of the distortion I am measuring is in fact the microphone distortion.... Let me explain why: The microphone in the test above is the Sonarworks Xref20 v4 (2015 version) whose maximum SPL is quoted by the manufacturer at 128dB. Although the...

Ok I’m with you. on a perhaps related noted, are the frequency response calibration files eg. Sound card, Microphone, used when calculating distortion? Or just for the correction of the amplitude (SPL) response?

That workstation is a 4K screen running at 125% zoom and screen capture 800 pixels horizontal. When it's rendered on a 1080 screen captured at 1024 pixels it looks like this. Not sure why, But let's overlook that for now. Here's the 24ppo stepped sine: Moving forward I will use log sine...

Hi John, thanks for your response. Windows 11. Sorry, I’m not certain I understand “checkboxes look huge” Is it the Y axis of 20dB per major division? I hear what you’re say about putting the mic closer. In practice I have to balance being able to get the mic close enough to minimise...

Will the real slim shady distortion plot please stand up? Can someone explain to me the reason for the differences? My cursory glance (non- mathematical/statistical trained brain) says it's related to noise polluting the measurement. But why?

Hello John, I’m currently on the miniDSP platform and thinking of migrating to the FusionAMP. I really like being able to upload biquads to the miniDSP directly after modelling in the EQ function. Will there be support for the FusionAMP in the future or the pipeline? If not; is there an easy...
