Can’t put ‘input’.

Free is free I guess.

I have a fully updated os in an iPhone 11.

Shows my apple AirPods as ‘output’.

Nothing shown as my ‘input’. I’ve tried with Apple Music and Amazon music.

Am I ‘barking up the wrong tree’ with my inputs/outputs?

A simple free EQ

For me to give anything less than 5 stars would be to “look a gift-horse in the mouth,” as they say. One confusing thing, though, is labeling the maximum gain as +/-1.0 when it is, according to the documentation, 12 db for the high/low and 24 db for the mid.

Doesn't work

It's very simple and set up to do exactly what I need. Unlike other apps which require me to connect them to my music libraries from other apps this connects right to my audio. This is amazing!¡! But it doesn't work😕

Not A System Audio Equalizer

There is a suspicious lack of low cost and widely available “System Audio Equalizers” This is not one. One should be built in and have spiders that will work on sound system wide. I figured that out and I’m not even a systems engineer, how incredibly short sighted! This app only works on the microphone, not with music, book reading or other audio applications. It’s another case of that cloying combination of monopolistic practices and extreme greed that defines this ecosphere so easily seen by the rise of “subscription models.” And perhaps these limits were externally imposed. If that were not the case, wouldn’t there be a surfeit of free or low cost System Audio Equalizers?
