This 5-minute test can help you detect a huge range of speaker/audio playback issues: missing channel, swapped L/R wiring, mono summing, channel level offset, speaker sensitivity offset, frequency response offset, EQ processing offset, audio signal or acoustic imbalances, inverted polarity in signal, inverted transducer wiring (woofer, midrange, tweeter), frequency response deviations and limits, buzz & rattles, speaker cabinet air leaks and port noise, transducer damage, DAC aliasing, room modes, bass crossover issues, flutter echos or ringing, echo/reverb processing, compressor/limiter processing, spatializer processing, L/R time domain offset, and more. *So, how clean is your audio?*

The best headphones earbuds I ever had cost 89 Cents USD... They were excellent... seriously.. I cracked them in the car door one day.. I re - ordered about 5 -7 pairs and gave them to real friends.. then one day.. they disappeared from Fast Tech and that was that... Peak Cheap Hi-Fi was 2015 FACT
Just used these tests to verify a volume issue with some wireless earbuds after cleaning them, this made it really easy to tell that the issue was fixed. Definitely need to use this in the car to adjust my eq in there though
Hey Outlier Audio, thank you very much! I am using your audio tests to debug audio setup issues between my browser and GnuRadio. I like the noise sweeps and channel checks, these help ensure that I'm finding all my finger and toes and sources and sinks in the audio chain. I will eventually try to hunt DRM and MA3 digital broadcasting from IQ sources in WebSDR and KiwiSDR.
There is one issue with this - youtube normalize all videos and all of them are significantly quieter than everything else hear able on PC. This test would need to be downloaded and then tested locally however I still not sure if we would download it it would be already normalized. You should deliver us ability to download it in not changed form.
You're welcome to download the Fast Audio Test files for offline testing here: outlierstudios.bandcamp.com If there's enough interest I'll upload the Extended Audio Test as well.
Thanks! This helped me notice that I need to insert my in ears properly if not it would sound like there's channel in balance. I think because when i insert it wrongly, only half the nozzle is emitting sound into my ear canal while de rest of the sound is hitting the other part of my ear which blocks it from being heard so it sounds uncentered because the volume of one ear bud is softer. Made me realize proper insertion is important.
Bro, this is a very important comment. At 4:52 min, it really showed of the difference in left and right channel problem. My headphone has a very very minor difference between left and right speakers of EKSA e 900 pro that is almost impossible to detect with normal testing as only at specific frequency only, the difference is noticeable. Your video at the time mentioned really picked it up. I have tested with both mono and stereo and now i am confirmed that it has the problem. I think that EKSA is supplying this model faulty only. I think they even don't know about this. This is a really shocking for me.
Wonderful, thanks, just bought some new Edifier speakers running them through a FiiO 10K... am very happy, apart from I have no hearing above about 13K (shit, I'm getting old). Thanks for putting this up, it all passed with flying colours.
Thanks for this! It sounds like there's a slight tonal difference in the monitors I've just bought. Is this an illusion because the sound is changing sides or does everyone else have complete perceived symmetry in tone? I'm even pointing just one ear at the monitors and they're right next to each other, to rule out assymetrical hearing.
This is really a common thing, to hear slight tonal differences between two (high end) speakers when listening closely to wideband A-B tests. It's almost impossible to have a perfectly indecipherable match in the real world, because of part tolerances and also acoustic asymmetries (although you've somewhat ruled out acoustics). If it's small but significant, you might consider EQ as a fix. For "smart" EQ solutions, have a look at miniDSP or Audyssey MultEQ stuff.
I can say with confidence that both of my phone's speakers are working perfectly. Although I have a question because they don't sound the same. The right one seems to be less bassy and more on the right side of the equaliser. Is this the stereo separation doing it's thing?
Could be stereo separation/widening processing like you said, but could also be mismatch in the two speakers - e.g. if you have a newer iPhone, the two speakers are pointing in different directions and probably have different specs for enclosure, transducer, etc. Apple is probably using separate audio processing for each speaker to match them more closely, but that can only go so far.
@@OutlierAudio I have an XZ Premium. It has 2 front facing speakers and they indeed sound different. The left is more bassy, more clear. The right is less clear, more on the voices. Together they do the work. If i have my head in front while the phone is in landscape I can feel the stereo sound, not only hear it. It's warm and really immersive. At the point that you play air sounds in your test, it feels like I'm really there when I close my eyes. Although when it's speakers play one after one, it seems that they miss something.
@@DenisLiasis I see - my guess would be manufacturing tolerances on the drivers/enclosures, but really could be any number of things in the audio signal path of that phone, including stereo processing like you mentioned
In Continuous Sine Sweep test 7, at end in the ultradark violet portion, I get a slight "fuzz" not quite staticy sound maybe 30% as loud as the tone, for both channels tests. What might that be, just range of the speakers? Bose Companion 2 series III
Does it sound more centered with the inverted signal, in all 3 signal ranges (low, mid, high)? If so, you might be better off flipping the polarity on one side. That said, car audio is extremely tricky because of all the reflective surfaces, the positions of the speakers, and the fact that the driver is off center. Even the best stereo soundstage will still be a compromise in a car, and a polarity flip won't have as clear an impact as it would on a home/studio listening setup. A couple more things to watch out for would be: if you have no subwoofer, the wrong polarity could kill your low bass, and also some modern head units have delay settings per-speaker, so this will have an impact on speaker phase (and polarity) as well. Finally, if you optimize completely for the driver, your passengers' sound could get bad.
I can relate which is what prompted me to buy a new and different model from completely different brand that is two times more expensive....yet I still hear the the problem so I conclude it is a software that had nothing to do with the hardware of your earbud or earphone. I tweaked the audio balance to fix it though may pose problem in gaming. You might be slightly tone deaf on your right ear and mine's does not because this problem does not suffice in my other device. The problem occured in my Android 10 phone while this seems normal on Android 7.1 samsung tablet
@@Vysair that explains why one is called right channel and the other is called Left channel. They are different channels and sound a bit different. The one is towards the right side of the equalizer, and the other speaker on the left. That's why they are called stereo speakers.
You know whats weird, during hte Channel matching - treble part my right ear is slightly higher pitched than my left, and on the bass part my right ear sounds like something rattling loose inside but left ear sounds perfect, i use DT990 pro 250ohm

Both, and more 👍 Just as when "listening to music" or "listening to speakers" you're actually listening to the entire signal path including the original recording mechanisms and also your own hearing.
I thought I had a problem with channel being quieter on my amp - changed speakers around and the other speaker went quiet. Tried different outputs, same problem. Plugged headphones in, same problem. Tried my laptop jack, then my DAC through the laptop, then my phone - same problem. Ordered a new amp, then while I was waiting realized I hadn't tested my headphones this way directly through my phone or the laptop. Guess what - SAME PROBLEM. All the white noise sounds lower in pitch and varyingly quieter on one channel on all of my devices through all of my sources. Of course I've switched everything around to make sure it's not just my ears. New headphones on the way, I'll update when they arrive. Losing my mind over here, almost suspecting this video to be a practical joke! But I probably just have cheap gear. Just found the same thing with bluetooth headphones from my phone and my laptop, so I don't think it's cables - crappy audio drivers I guess. Sennheiser HD6XX should help me figure it out. I'll find some better sources. Will update
The filter parameters are the same, but the noise itself is entirely uncorrelated and will appear as two distinct sources at the Left and Right speakers

It could be that one of your drivers has sustained light damage and isn't producing sound correctly.

are both the L and R exactly the same?? i play it in 2 of my monitors and L and R dont seem to be exactly the same
I agree, tried this video on multiple speakers and the channel matching section doesn't match on any of them
Huh,I thought that my Beyerdynamic DT880 sound bad or my ears are not equal but now I see I am not the only one hearing the difference
Yup, exactly the same. Identical in both time and frequency domains.
If thata the case, my left ear is worse than my right....
Excelente teste, um dos melhores que já ouvi!
0:04 Why this noise is not exactly the same in both channels?
the continuous sine sweep gives me buzzing noises. what do i do next

What a chad, he hearted my comment!
on 3:31 ?? is it the same as right or is there a diff tone ?
