I just started using UAPP on my M11, can anyone explain to me what enabling any of these would do?
EQ
Morphit
Crossfeed
Parametric EQ
Balance
Bitperfect
And is there anything else I should do settings wise?
I'll give it a try for some of the terms according to my understanding:
1. EQ - this is where a device can alter various frequencies to make those frequencies louder or quieter. For example, if you find the bass is weak, then you can use an equaliser to increase the volume of the low frequencies. There are also a couple of types of equalisation: a standard EQ (the one under discussion here) and a parametric EQ discussed later. The standard EQ is often known as a graphic equaliser. With a graphic equaliser the set of frequencies that you can make quieter or louder is fixed.
2. Morphit - this is a great add-on if you want to perform sound 'correction' for headphones you are using. It can help to make the sound more pleasing by boosting some frequencies and suppressing others based on which headphones you have chosen in the settings in order to compensate for the headphones' deficiencies. As @alekc has mentioned, there is a limited list of supported headphones. I've tried it with my Beyer T1.2 and T5p snd the transformation in sound is quite remarkable. However, I prefer no alterations in sound whatsoever.
3. Crossfeed - this is where some of the sound from the left channel is sent to the right channel and vice-versa.
4. Parametric EQ - this is an evolution of the graphic equaliser mentioned in point (1). Here, you can set the centre of the frequency that you want to make louder or quieter. In other words, you can program the frequencies and then make those programmed frequencies louder or quieter based on your hearing preferences. A graphic equaliser often has more 'sliders' but each slider is for a fixed frequency. A parametric EQ usually has fewer 'sliders', but you can set the frequency of each one.
5. Balance - this is adjusting the relative volume of sound for the left and right channels. For some reason you may want to increase the volume from the left earcup of your headphones or vice-versa.
6. Bitperfect - this is when a device or app can take a digital audio signal (for example from TIDAL, Qobuz, etc) and convert it into an analogue audio signal for listening without sending that digital signal through the device's audio mixer. Audio mixers often downsample (convert a higher resolution digital audio signal to a lower resolution one) or upsample (convert a lower resolution digital audio signal into a higher resolution one - but you won't get any more details in the sound!) a digital audio signal before mixing it with other sounds from the OS or other apps, before finally converting it to an analogue audio signal. This invariably leads to sound degradation, which you may or may not be able to notice.
I may have the wrong understanding of some of the above so I hope someone will correct me where I've made a mistake!
