For Android? ChromeOS? I just purchased SpotEQ31. It has 33 bands in the pro version. And a subscription model for 2.99 a month for some extra features. I just wanted to try out a 31-33 band EQ on Android that I could just download without going into dev mode or unlocking the bootloader or rooting on Android.
The App installs and works on ChromeOS or a Chromebook/Box.
What surprised me is that you do indeed get 33 bands. But the 60hz band seems to be MIA. Not sure why
You also as you can see, get independent equalisation of both channels which is a new one for me on an app.
It also has some extra stuff bellow:
The basic free version is all you need. AND PLEASE TRY IT OUT FOR A WEEK BEFORE YOU BUY!
One of the problems I ran into was distortion on the left channel, But also it put out a ghost image of the left side audio on the right with my testing. I don't know how prevalent this is. It might have to do with hardware, so try before you buy. I'm still doing testing with it.
It is in my opinion a very capable Application. It works. I tested all bands so far, impressed that it works, but not willing to use it as a dedicated solution yet.
It also has a settings menu to take care of some Android related audio routing issues.
The bands are selectable, but this is the full 33 monty here:
These are the list of Bands you can choose and a screen shot:
7 Bands
11 Bands
15 Bands
21 bands
23 Bands
27 Bands
31 Bands (33 shown prior)
Presets include these settings
Also as mentioned before, the stereo output can be E.Q.ed independently.
It does have a visulizer function. I have not got it to work yet or tried to bother with it.
It also features left right channel controls and gain etc.
Effects are these
With the following increments
I have only one BIG gripe about this kind of great software. Sometimes, you need a Peter at PS sound to walk your through it all Or Danny to give you the Mr. Rodgers on how these settings can be used. It would make this much more accessible.
On my Chromebook, I was unable to get rid of the distortion on either bluetooth or Headphone output. So my testing as for the eventing stopped there. I still have about 5 devices to try this on.
The nice thing is that it is EASY to use out of the box per say, and the only Harry potter is what you get with the subscription?
I tried it out for a quick run, but did not see any initial benefit to something like the Dolby Atmos EQ app that came stock with my Phone. Works a charm really. Even with AmazonHD.
I still wish they had more bands in the 20Hz to 250 Hz region. And maybe a PEQ option.
It is still under active development. And the Author is happy to answer questions with a fast response.
The person who uses this app is obviously someone who has some kind of dedicated measurement microphone and understands how to use tools like room EQ Wizard, etc.
there is a beta program. in the code from what I can tell so far is Rock Solid. the stock layout is white and it's well worth the $12 for me to have a black background.
the text readability could be improved a bit. but it works.
Its not crossover software by any means, but it may be useful if you need a Program that can take care of dips and peaks and unwanted response spikes or Resonance curve issues with some drivers. this works particularly well with speakers that happen to have a crazy breakup or response at crossover frequencies with analog crossovers.
I didn't experience any problems while switching Media or different application windows that kept running in the background so that's a plus, essentially was hiccup free with my limited testing.
you are also able to import values from different instances on different devices so you don't have to start from scratch so that's a plus. I think you need to be on the subscription-based model for that to happen although I believe you can manually insert files in as well if you are able to access the file system.
it seems that something like this would be more useful for the home audio crew out there and those with simple two channel setups. the fact that natively runs in Chrome OS without a hiccup is a real bonus for those of you looking for old Chromebox devices to use as playback media streaming front ends under native ChromeOS or Android native devices and does not require root privileges to install or run.
application was tested with Native local files. Spotify, and Amazon HD as well as YouTube.
test rig was a Asus Chromebook cp101a with 2GB of RAM. the program remains Snappy and did not experience any sort of lag in its operation.
the actual EQ sliders don't work as a regular EQ with instant feedback you have to point click and move to the location and then you will experience a change in its equalisation parameters you have set after you drop the slider to its location and then it will take effect. It does not happen realtime.
not sure how this works with multi-channel set-ups such as Amazon's movie streaming platform but it does seem to work quite well on to channel setups with what testing I have done until I ran into the Distortion snafu on the Left Channel.
