    Phase Corrected Equalizer

    Now what exactly does this do? does it simply buffer and get rid of phase shifts and distortions where the # is to what degree? i've heard things about it boosting in certain ways.

    wikipedia has an article on it: http://en.wikipedia.org/wiki/Phase_cancellation

    doesnt sound terribly useful to me - a hell of a lot less than say, a user settable power off timer =D

    it is useful, if you eq a noticible amount then there will be bad distortion and missing frequencies with digitla eq's

    i'm just wondering how the control on the m6 works with its 0-9 options.

    i dont know the techs on how it works but I use it(setting 3 or 4) and it does make your music sound clearer somehow...over 3 or 4 i find it enhances the higher tones too much making my ears hurt

    Phase cancellation has nothing to do with this.

    ok after some googleing and reading stuff i dont understand much about it seems the PCE is a way to "recover" missing bits of data, in this case audio data

    Seems like its also applied to radio broadcasts to recover the bits that were lost during transmission.

    maybe I am totally off the mark here but it seems like what the PCE does is "recover"(more like educated guesswork using an algorithm) the bits of missing data in the audio stream making it sound "better"

    Personally I do use the PCE at 3...it does seem to make the music sound more crisp and full... however, over 3 its my personal experience that it tends to distort the sound

    Err0r, I didn't find any usefull information from this thread. Almost all information is misleading and false and that's why I started a new thread.

    It doesn't recover any missing data. FLAC and mp3's are affected the same way and how could lossless have any missing data?

    And here's my original post:

    "Phase corrected equalizer", does anybody know how does this technically work?

    I use my shure E4's (flat settings) and for some songs PCE set to 1 does miracles. It adds depth somehow. I have figured out it boost frequencys at 2.5-5kHz by playing with EQ, it creates similar effect at those frequencies but this PCE does something even more (thought it increases hiss..).

    I wonder if similar effect will be reachable with EQ.

    I dont think phase correction "restores" any bits lost during compression of an audio file. What it really does is similar to equalisation, it boosts the bass, treble and vocals. However for some reason, it recesses the lower midrange to my ears and makes music sound less accurate.

    It does however make your music, more musical... it adds a certain depth of warmth to the music. The reason why it accentuates hiss is because there is a noisy output from the M6 originally. Phase correction increases the loudness of the music (For DNSe) which is the same result as boosting a parametric equaliser. Now, if the output was clean, there would be little to no hiss and hence white noise cannot be accentuated by the phase correction.

    Personally I don't use PCE, because I rely on sound reproduction through earphones/headphones. In other words, I use headphones depending on the sonic characteristics they provide, this negates the need to use EQ or sound enhancements at all. Of course, if you have a basic pair of earphones, then sound enhancements can make your listening experience more enjoyable.

    Just what I found during google'ing:

    http://www.orionstudios.com/SpatializerPCEWeb.html
    http://www.orionstudios.com/Spatiali...dphoneWeb.html

    So I don't understand really much, read only marketing bubbles.

    This Natural Headphone settings in the Spatializer are just a joke for me.
    They cut the highs and put the sound underwater, to much bass!!!

    For PCE, I'm using level 3, because I found that the voices are getting more in the foreground. Like this.

    ViBE I put to level 3, bass is more sharper ... if this is possible.

    It's okay that I can adjust the settings in Meizu players. The EQ is a great gift for all with a good belive they can get the best for every single song. :-) I set it to an almost flat setting 60hz to -7 and 150hz to -4 because of the bass dominance of my earphones.

    But now I want to trust the Spatializer-algorithms, because I spend to long to try to get my lousy ear adapted to my great AKG earplugs. :-)

    enjoy the music.
    Small moves, Ellie, small moves.

    hehe, actually if you've noticed, "natural" (well it is natural, sounds like your using headphones underwater), 3d surround and Vibe make your music sound horrible. Only feature worth using from the DNSe featureset is the phase corrected equaliser. Although the capability of PCE decreases as the quality of your earphones/headphones increases.

    On lower end earphones, PCE makes them sound more enjoyable, but on high end earphone, you can tell PCE makes your music artificial.

    The equaliser is great, i tested out all the frequencies and the changes in relation to each frequency is fairly accurate, too bad i dont equalise my music =P

    The other sound enhancements worth using are the bass boost and treble boost. They do a fairly good job if you don't know how to adjust the EQ.
