System-wide EQ with multiband compression, limiter, and audio-visual feedback.
About this app
To start off there is really no "free" and/or "open source" alternative to Wavelet and Poweramp EQ that pairs the full DynamicsProcessing API with real audio-visual feedback, and I felt like after using both of those apps among other various EQ apps that there were huge shortcomings in terms of the features & accessibilities they offered. When I started developing this app I wanted to have both a powerful parametric eq function with minimal permissions; this is why I choose to use both the DynamicsProcessing & Visualizer APIs as the framework for this app as you only need minimal permissions for both of them to work in tandem. There are shortcomings from both these APIs, but I'll discuss more of that later.
This app is built off of DynamicsProcessing API; this is the same API that Poweramp EQ & Wavelet both use but I felt in some aspects they weren't really being able really squeeze out the max potential that this API can offer.
As someone who comes from the audio production & IEM world I have a lot of experience understanding what both sides of those worlds want and wanted to be able to take advantage of both to create something that met my creative endeavors.
Using the Visualizer API I wanted to give users a way they can reliably cross reference visual data with audio data; this is both useful for the main EQ portion as you can visually reference audio changes you make, but this comes more into play with the Limiting & Multiband Compression sides of the app. While these features are for use in the DynamicsProcessing API; and many apps like Poweramp EQ & Wavelet (who premium locks these features); they just add knobs/sliders in and expect the user to understand exactly how these features work and without real audio-visual feedback, users aren't really able to take advantage of these features in their full potential. This is the reason why many DAWs and VST Plugins use audio-visual feedback with these functions specifically.
Using Visualizer API with these DynamicsProcessing features; you're really able to get an intimate audio-visual feedback loop that gives you complete control over your audio framework.

What's New in v0.0.15-beta
Imported from the F-Droid repository index.
- - Remote EQ Mode (experimental, issues #35 / #55): control the app from another device on your network. Set the audio device to "TV" (a PIN appears), your phone to "Remote", pair once, and the phone's full EQ UI drives the other device live — bands, preamp, power, presets, even screen navigation. The controlled device shows a "Remote Controlled" lock overlay and its notification reads Remote / Remote Controlled while a link role is active.
- - Pre/Post EQ Interleave (experimental, issue #26 follow

Installation Guide
Open Settings on your Android device
Go to Security → Unknown sources (or Install unknown apps)
Enable "Allow from this source" for your browser or file manager
Open the downloaded APK file from your Downloads folder
Tap "Install" and wait for installation to complete
Launch the app from your home screen
Make sure to re-enable Unknown Sources restrictions after installation for security.
How to install this safely
How to verify the file you downloaded
Before you install anything, confirm the file is the one described here. On a computer, run shasum -a 256 your-download.apk (macOS or Linux) or certutil -hashfile your-download.apk SHA256 (Windows), then compare the output character-for-character with the SHA-256 on this page. If a single character differs, the file is not the build we recorded — delete it.
What the signing certificate proves
Every Android app is signed with a private key that only its developer holds. The fingerprint on this page is a hash of the matching public certificate, and it proves continuity rather than identity: it tells you a build came from whoever signed the earlier ones. Android enforces this at install time — if a package claiming to be com.bearinmind.equalizer314 is signed with a different key, the system will refuse to install it over your existing copy. A fingerprint that changes between releases is worth pausing on, because a repackaged app that has been modified by someone else cannot keep the original signature.
How to roll back to an earlier version
If the current release misbehaves, 0.0.14-beta is the last build before it. Android will not install an older version code over a newer one, so you must uninstall Equalizer314 first — which clears its local data unless you have a backup. Reinstall the older APK only if its signing fingerprint matches the build you already trust, and check the API range: an older release may target an Android version your device has moved past.
Why we list sources instead of hosting everything
The official store channel is almost always the right choice: it updates automatically and carries the publisher's own distribution guarantees. A direct APK is useful when a device has no store access, when a rollout has not reached your region, or when you need a specific version — and only when the publisher has authorized that copy. APKBrowse does not list pirated, cracked, or unauthorized rebuilds of Equalizer314, and a listing is removed when the evidence for it stops holding up.
