testing

I just read yet another person trying to defend a position related to audio by referencing "double blind studies" generally. The idea always sounds great as a listening test. Truly see if people are able to notice differences between things. If we use a fairly controlled method, this information...

Threads like this one show the limits of the tests currently carried out on PAs, because they are simply too magnifying and ignore one or the other parameter. What is the goal of a PA? Quite simple really: it should make a weak input signal usable for a loudspeaker. Technically speaking, it is...

A few years back I was really into repairing and using cassettes. A bit of a tape tech if you will. Also, I would source old hifi, refurbish it and flip it for a little income. It was a distraction, and just about all of the tape stuff, tapes, walkmans, separates, all gone. I have one Walkman...

After listening to a pair of M-Audio BX4 speakers and agreeing with the results of @Weeb Labs review, I am tempted to compare the following budget monitor speakers: 1/ M-Audio BX4 $120 2/ PreSonus Eris E4.5 $180 3/ NEUMI BS5 $110 Other than my listening impressions, what can I do to test these...

Hello, I am new when it comes the room acoustics, I have been mixing in headphones most of the time, and now I would like to start mixing on speakers , I have set up my speakers and my best listening position in my room, it is a small room with a slanted roof. I have ran some test on REW with L...

Please share the best practises. I have a pocket audio player; can certainly save test tones into its memory and play them back. Any ideas how to run a RMAA test, Multitone sweep and such?..

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...

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...

I found this interesting and maybe you do too :) Any thoughts? Forum link here with test data: https://linustechtips.com/topic/1387053-i-spent-a-thousand-dollars-on-hdmi-cables-for-science/

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...

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"...

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...

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...

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 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...

Folks, Only for the brave: I'd like to solicit your feedback and suggestions on DeltaWave null-testing software. It's an early preview, so please be gentle! Details and software download are available here: https://deltaw.org An example report produced by DeltaWave comparing two USB cables...
