distortion

In a recent thread I asked whether or not the Klippel NFS can create polar plots of distortion measurements. @amirm clarified that it's not set up to do so and that in any case distortion would show no spatial dependency unless the source was acoustic, i.e., the distortion was caused by the...

Hi there. I'm a long time audio enthusiast with decent equipment, but as I have taken the plunge into computer audio, am having a little problem. I'm hoping that someone can explain what the issue is and how to fix it. I have ripped my CDs (pretty much pristine) to a new Windows laptop (SSD...

Speakers are usually able to accept quite high impulse power and measuring of speaker distortion by sine bursts would show if we are still in relatively linear region. The pain of sine burst distortion measurement is in length of the burst, which may not be long enough to get sufficient...

Sorry if this has been asked before, I couldnt find an answer so far. When looking at headphone amp measurements the distortion always goes down the more power you are putting out of it, except for when its clipping at the end. Is that correct? What is the physical explanation for this...

When I first saw schematics of vintage Kenwood KA-5010 amplifier, 2 years ago, I was immediately attracted and decided to build a circuit copy, better say a copy of the circuit topology with some newer solid state parts used. There were 2 points leading me to this decision - frequency...

I’m having noticeable distortion while streaming via Bluetooth from a MacBook to my new DX7 Pro DAC using the Audirvana player. See the attached files for FR at 1 khz via USB (no distortion) and BT (obvious distortion). The distortion is basically the same frequencies (not harmonic) when tested...

It felt inappropriate to post this in Amir’s “Should we (I) get into speaker testing & measurement” thread, so I started a new thread here. One of the sites I follow regularly on the internet is Lowbeats, see: https://www.lowbeats.de This is a German HiFi-Online-Magazin, as they call...

I'm interested in this. Loudspeakers probably add more distortion to the reproduced sound than everything else in the chain, but it's rarely talked about. I have a gut feeling that the infamous subjectivist claim that some systems "measure well but sound bad" may partly be about speakers that...
