    What mechanism is causing feedback in this setup?

    The other day, when performing near-field measurements of my study speakers (as part of designing a crossover for them), I started getting feedback when measuring close to the tweeter (Seas D2010/8513) with no test signal being generated. Measurement setup was: PC USB->Scarlett 2i2 audio...

    Windows 11: Windows Subsystem for Android

    This thread talks about the "Windows Subsystem for Android" feature for Windows 11. If you don't know what it is, it's basically an android emulator (for x86) and native android (for ARM). This feature was available back in October for Windows Insiders but now you can install the "Preview" right...

    How to test devices

    Hey all! I've just discovered this forum and am eager to dive into some measurements on my own equipment. Only problem: I can't find any tutorials - I can't even find what software y'all use! I've searched around a bit but can't find a thing - I'd be grateful if someone could link me to...

    Dubious about SPL used by objective testers

    link I am dubious about at least one aspect of this methodology. For consistency, all speakers should have the lower-decibel chart in their review. Leaving it up to humans to decide, subjectively, if "it appears that the speaker is being strained beyond its output abilities at this level"...

    How Should I A/B Test DACs?

    I am fairly new to the enthusiast audio community and have been doing a lot of reading on ASR. Upgrading up my desktop DAC/Amp setup and I want to see what differences I can actually hear. I want to do some testing. I will be using my own equipment and borrowing from friends. Here is what I...

    Would You Buy Speaker Cables If LCR Testing Was An Option, I Did

    One of my first introductions to ASR was Amir’s article/review titled “when 12 gauge wire isn’t 12gauge”. Ok, I knew that “Reduced Dislocation Density” was probably just cable marketing...but various 12 gauge wires having different measured properties. Yikes! A few months after reading this...

    Is MiniDSP SHD's ADC performance in the same ballpark as RME ADI-2 Pro fs?

    Given that the MiniDSP SHD and the RME ADI-2 Pro fs both use the same AKM chips, have similar specs, and in Amir's DAC testing showed very similar performance, is it safe to assume that the ADC performance of the MiniDSP SHD is likely to have a SINAD within a few dB of the RME ADI-2 Pro fs? I...

    Complex Load for Power Amplifier torture testing

    Complex load for power amplifier torture testing It has been discussed on the forum that we should test power amplifier not only to purely resistive load, but also some kind of the complex load should be used as well to verify amplifier stability and ability to drive complex load that may occur...
