Actually it is something new for Android.
So Audio Evolution started cooperating since some time to bring the company Tonebooster VST's as in-app purchases and the first ones expanded Audio Evolution to make it easier than before to mix and master with good effects as a good reverb and limiter and even a de-esser.
One thing that have been missing though is a frequency analyzer and in this new addition it comes built into the EQ making things much easier for mixing- But it is so much more as it comes with a bunch of different filters and other functions plus... da da da mid / side possibilities!
( Personal note- Mid / Side implementation can really help a mix but it is also very easy to fuck it up if you do not know what you are doing. To avoid fuck-ups- when mixing using mid / side, check the mix in mono once in a while. )
That is the first app on Android that allows this. ( It is possible to do it with some tinkering in SunVox, but it is not convenient and not easy).
In either case I do think that this makes Audio Evolution the best choice for mixing and mastering your tracks and not having to stray outside of your device!
Especially when it comes to recorded music but also to electronic music and rendered audio if the apps used had limitations or just to make it easier...
Maybe a small warning though it is possible but on a smaller screen good eye sight is a plus.
The in-app purchase is 1.99 € / 2.47 $ and for what it is, in my opinion it is a small price to pay.
Official EQ description:
TB Equalizer is a versatile equalizer with a wide variety of filter prototypes and channel modes. Each of the 6 filter sections can be configured to run as low cut, low shelf, digital bell shape, analog bell shape, high shelf, notch and high cut filter with variable filter gain, frequency and quality. On top of these standard filter types, Pultec-style low and high shelf filters are supplied as well.
Each filter section can also be configured to run in stereo, left only, right only, mid only, or side only. The overall equalizer curve can be morphed between 100% and -100% continuously.
TB Equalizer has an integrated spectrum analyzer that can display overall power spectrum, left/right pan, and spatial ‘width’ expressed as the ratio of side over mid signal.
