Searched this video for the sole purpose of seeing which ear bud of these cheap-ass earphones is L or R, since the letters completely faded off. Only needed the first 4 seconds of this video. 10/10, would test again.
I read this comment because I watched the video and scrolled down. now I am making another, needless comment of my own because I've got nothing better to do.
For all my headphones/IEMs, no matter how expensive or fancy, always play this first after a purchase or repair. More detailed testing is done by my ear and audio preferences, but this is 100% the best quick test on the market.
by far the cleanest, most useful and accurate headphone / speaker test on youtube. The buzz/rattle sweep works very well. I get the occasional buzz on the lower end of the sweep while using bluetooth, but perfect clear sound using the 3.5mm cable
This is exactly what I was looking for! I had no idea what would happen if the polarity on the speakers were reversed. I do now thanks to your test. Thank you for taking the time to do this and to do it right and in a reasonable time.
I love you. I just found out the polarity of my speakers were off. Didn't notice I crossed the wires on the speaker. Your video told me the problem. I had no idea speakers would even make sound wired backwards, let alone causing them to have flipped polarity. Thank you, thank you, THANK YOU!!!!!!!!!!!!!
Went to google, searched for "sound test for speakers", randomly clicked the first youtube video, satisfied with testing and finished within the first minute. Mainly because my eardrums and speakers exploded after 40 seconds.
Thank you for this outstanding test. Would you consider possibly breaking it down into its component parts in separate videos, so we can use the Loop function in UA-cam to conduct only the tests we need? It'd be really appreciated.
If I heard different sound during 0:13 Speaker Polarity (Normal, Inverted) , It has a problem? I just bought speakers. I heard difference at left right sound. also normal ,inverted
Thanks a lot ! I was running my hiFi system (Beard amplifier and La Scala speakers) thinking for 2 weeks that voices weren't as centered as they should... polarity was inverted on a speaker after I cleaned them two weeks ago... very stupid mistake... to stupid to have thought about it without listening to your audio test !!! So thanks, and musical kisses from France.
This video helped me realize how my headphone cable was broken. The part that processes the audio on the left side doesn't work properly, causing it to be quieter. With a couple of fixes from the audio console, my headphones work good as new now. Thanks!
Me: "Just got a new pair of headphones, let's test them out" (have headphone on left ear only) Earphone: "one, two, one, two" ME: "WHO THE HECK MAKES MONO BLUETOOTH HEADPHONES???? SMH now i gotta get a different pair..."
Perfect! Whenever i feel like my cables are loose or i need to test a new speaker set i will use this clip. Downloaded! Thank you very much for compiling all the effects :cookie:
Assuming these are speakers (not headphones), the cause could be room modes. Have a listen to my Audio Problems video *using headphones* to get an idea of what room modes sound like and basics of how to deal with them.
One question regarding test 2, "channel levels". The right channel sounds a bit lower pitched than the left channel. Tested this on my speakers as well as on my headphones. Different amps, both solid quality. Is this normal, or is my hearing busted? When performing the polarity check, I get a perfectly centered sound though.
The L & R signals are identical in Test 2, so in a properly calibrated setup they should measure (and sound) the same. There are many variables in any setup but you're right, it could be your hearing - a simple test is to flip your headphones around. Try playing the R headphone speaker into your left ear, L into right ear. If you still hear the same issue - i.e. right ear sounding lower pitched - it's likely your hearing. If not, it could be the headphone/speaker, or any signal processing that happens before it (amp, dsp, etc).
This helped me. The sound heard like it was coming only from one side of the headphones and this made me know that the other side works a little bit, but not good.
Please help, the left and right speakers sound slightly different with the same audio (0:04), also, when I try the left/right experiment on sine waves, the left one is slightly distorted, while the right one isn't.
Hi Groszak. Unless the speakers are mirror imaged, that is equal distances from reflecting surfaces, and unless those reflecting surfaces are very alike, you would expect what you are describing. Regarding the distortion, swap the channels and see if the distortion follows suit, if it does something further up the chain will be responsible. All the best :).
This found an issue! Center image stability showed on my sleeping head level adjusted speakers that I had L and R wires crossed on my Sound Engine speakers for -months-, how embarrassing ! I had to replay it a few times to be sure but the pupping both ends of the copper color speak wire red, well that doesn't lie, it was spot on, thanks
At 0:04 the top/left one always sounds higher in pitch to me using my laptop's speakers or over-the-ear headphones. When I put my headphones on backwards, the right one (which is supposed to be left) sounds higher.
I would guess the offset is not caused by a hearing problem. It's possibly a laptop sound card issue, a cable issue, or simply that both your headphones and speakers happen to have a similar offset because of manufacturing tolerances. Listening to the same video on other devices, headphones, and cables can help pinpoint the source of the problem.
Many thanks for this video. Now I know that my 2nd smaller pc isn't stereo in sound... It's allmost MONO! Ah-well.. Through HDMI over my tv (the 2nd monitor) it IS a 100% stereo, odd. I don't know if you know, but do you have an explanetion why?
Yes actually lots of smaller devices will only have a single speaker driver, requiring summing electrical signals to mono. Others might have two speaker drivers and output "stereo", but the speakers are so close together that the resulting sound is very close to straight mono. As for HDMI output, yes since this is a digital audio & video connection, it should transmit the digital audio in the same format as the source (mono, stereo, surround etc)
@@OutlierAudio Well yes, it has a mono speaker at the front. But if i plug anything in with a 3,5mm jack, front or back, ext. speaker or headphone(s), it is sort-off stereo: 50% (volume) off the sound from the left you will hear on the right side, as the other way around.
During the "Normal" section, the noise signal is identical in the L & R channels. During the "Inverted" section, the R channel is inverted (negated), relative to the L channel. This tests relative polarity between L & R channels, to make sure they are aligned. Absolute polarity of the system could still be incorrect (e.g. flipped wiring on both L & R speakers) while passing this listening test.
+Outlier Studios Thank you! So my ebay headphones are polarized the wrong way on one side. Wondered why they sound so strange... So time for resoldering :-)
excellent test sounds and perfect for me getting the balance correct. One issue is that the centre sound sounds better i.e more central than 2 speakers, when the video saying 'inverted'. how to I change anything to play inverted (which should then be normal?)
Hi . Great video. Thank you for that. Just one question iam running trough amplifier 2 speakers and when it says inverted that is when i get image centre . How do i solve it since upon checking my connection + and - they are connected correctly both speakers with amp. Do i switch both or one?? Thank you.
Very useful test, thank you! Question: i'm testing a subwoofer with an amplifier which has a dedicated mono bass channel, on normal polarity i have sound and on inverted polarity i have silence. Is that correct?
Great! Yes that's exactly what to expect with mono summing (L & R channels electronically or digitally added together). And for more thorough testing of polarity across the spectrum lows-mids-highs, try the Extended Audio Test version
In the phase test Normal sounds like it is primarily in the right ear, and the inverted sounds like it is primarily in the left ear. Is this intentional, or did I do something wrong when changing the Jack connector for my headphones?
How about the Channel Levels test? If L and R channels on the headphones sound at equal volume, then during the "Normal" section of the Polarity test, the signal should sound in the center of your head. If the channels do not sound at equal volume, the image will be skewed accordingly. This could be a problem with headphones, your hearing, or anything else in the signal path (e.g. a "balance" control or poor wiring connectivity). As for the inverted section of the Polarity test, it does happen that this can sound skewed towards one ear. It's an "unnatural" signal that does not resolve well psychoacoustically. The key thing to listen for is whether the Normal signal is distinct and in the center, versus the indistinct Inverted sound.
I have a home theater 5.1 surround speaker setup and for some reason my Velodyne subwoofer is not playing below 35 Hz or between 60-90 Hz. My B & W Center channel speaker takes over at those frequencies. Do you know what the problem might be?
About the below 35 Hz issue, all subwoofers have a natural low frequency cutoff frequency below which they have declining output. 35 Hz sounds on the high end for a cutoff of a dedicated large sub, but that could be because of the in-room behavior (room modes) related to the room dimensions, subwoofer location, and the listening location. Maybe try relocating the sub away from the wall and/or changing the listening location to a position where you get a lower effective cutoff if that's a possibility. Not sure if you mean to say your B&W Center takes over below 35 Hz because that would not be normal at all. About 60-90 Hz, all 5.1 surround speaker setups will have a bass management frequency in the ballpark of 100 Hz, so that could be what you're referring to. It's normal for the output to transition from the sub (the .1) to the satellite speakers (the 5.) around that point.
