Audio self tuning: how it works?

[Bhonder]

Question for Xperia developers: how does it work this feature?
Is it true, and how, that it measures the performance of the user's ear?

By the way, I have some headphones from Phillips (she9000) that worked great with Nokia 701 but poorly with Z3c. Z5c gave them a new life.

Are you referring to the Music app? if you are, you might want to contact the app developers

Hi,

If you're refering to "Automatic optimisation" under sound effects on audio settings. If i'm not wrong that don't really go well with non Sony ear/headphones it also can be a posibility that relate to compatibility i guest.

Since on the older days the firmwares allow user to select the specific ear/headphones models to optimise the sound and with the newer phone firmware the list of headphones is nolonger there, but the newer firmware is capable to auto detect the native sony ear/headphones that you use.

So i forseen that this is a compatibility issue with 3rd-party ear/headphones or it can be even not support for 3rd-party at all.

Suggest you to turn/switch that off to see if the music sounds better. Hope this helps to answer some of your question.

I remember earphone selection of old firmware but it was limited to Sony's own stuff or a generic device as default.

Now auto tuning, in addition to working well with Sony's own earphones, does a real good job with other brands too.

I've tested with Phillips she9000, which resurrected to a new life, and Xiaomi hybrid which was great with z3 too.

Hi,

It does work with a small amount of other 3rd-party earphones, but there is no guarantee that it will work with any non-sony earphone. No Offence.

btw if the optimizing is off does the sounds gets better then before?

EDIT/Adding: tested on Z3 but the Z5 are different model. hardware to build the phone are also different, the recent sound chip for the Z5 may also related to the support.

When optimizing is off the sound is worse if the device never seen that earphone before. Then gets better.

I tested it on my wife without letting her to see the optimizing animation. When she said that the sound was better, the display was showing that optimization was performed.

But how does it work ? My JH16 Pro aren't showing any difference If anything there is a lack of bass ( below 60 Hz ) 

Mind you it's an IEM with 8 drivers including 4 subwoofers in every ear...

Hi, well is that is the case then just leave it on lol.

I'm using shure se535-v so far so good, since it won't really work properly with some earphones. I would suggest you to wait a little until the phone gets updated to 6.0 and see how it goes right after that.

Anyway the update will be up quite soon. Since all other manufacturer already roll 6.0 i also don't see sony will leave too far behind the rest.

Hope that after the update it goes better for your earphones, otherwise you may want to look for something else.

BTW my shure earphones dont work properly on my old Z3+, so as i say can really be a compatible problem.

ok all good, but do we've any clue how this thing works? how the phone with a pair of headphones can "analyze my ear properties"? seems like a marketing trick to me.

In order to analyze my ear properties, the phone need to playback specific frequencies, get my feedback and then generate the appropriate eq for each of my ear. (like a basic acoustogram )

Hi,

Is alot to explain, but i believe the link below should be able to help you further understand how this works.

And some of the hardware requirement should also be supported by the mobile phone itself. Just like our Xperie Z5.
