AndroidEqualizer

Android Equalizer View that can also manage the audio track frequencies

Add Equalizer in your Android app

How To Use

STEP 1

In settings.gradle you can add the repositories you want to add to the project:

repositories {
        google()
        jcenter() // Warning: this repository is going to shut down soon
        mavenCentral()
        maven { url 'https://www.jitpack.io' } // this is the line to be added
    }

and:

dependencies {
      implementation 'com.github.bullheadandplato:AndroidEqualizer:2.2'
}

if not using AndroidX. it will not have DialogEqualizerFragment or any other improvements

dependencies {
     implementation 'com.github.bullheadandplato:AndroidEqualizer:1.0'
}

STEP 2

For Equalizer in dialog

 DialogEqualizerFragment fragment = DialogEqualizerFragment.newBuilder()
                    .setAudioSessionId(sessionId)
                    .themeColor(ContextCompat.getColor(this, R.color.primaryColor))
                    .textColor(ContextCompat.getColor(this, R.color.textColor))
                    .accentAlpha(ContextCompat.getColor(this, R.color.playingCardColor))
                    .darkColor(ContextCompat.getColor(this, R.color.primaryDarkColor))
                    .setAccentColor(ContextCompat.getColor(this, R.color.secondaryColor))
                    .build();
            fragment.show(getSupportFragmentManager(), "eq");

For Equalizer in your view

Create a frame in your layout file.

<FrameLayout
        android:layout_width="match_parent"
        android:layout_height="match_parent"
        app:layout_constraintBottom_toBottomOf="parent"
        app:layout_constraintLeft_toLeftOf="parent"
        android:id="@+id/eqFrame"
        app:layout_constraintRight_toRightOf="parent"
        app:layout_constraintTop_toTopOf="parent" />
        

In your Activity class

 int sessionId = mediaPlayer.getAudioSessionId();
        mediaPlayer.setLooping(true);
        EqualizerFragment equalizerFragment = EqualizerFragment.newBuilder()
                .setAccentColor(Color.parseColor("#4caf50"))
                .setAudioSessionId(sessionId)
                .build();
        getSupportFragmentManager().beginTransaction()
                .replace(R.id.eqFrame, equalizerFragment)
                .commit();

Equalizer stops 10 seconds after exiting the fragment

After 10 seconds or sometimes more than that of pressing the back button and exiting the fragment, the equalizer stops and does not work until after opening the page again.

Thanks in advance.

How do I export processed audio

Unable to customize the colors of seekbar and switch.

Hi. Sometimes it works, sometimes it doesn't. I couldn't figure out what caused the problem. I didn't get any logs about this problem

Music playing in the background

Hi, how can we remove this song playing in the background ?

adding enable and disable equalizer.

Am trying to add enable and disable in my app so i tried below but unable to save setting in shared preference. So kindly help me to add this function. below is what i tried.

private void loadEqualizerSettings(){
        SharedPreferences preferences = PreferenceManager.getDefaultSharedPreferences(this);

        Gson gson = new Gson();
        EqualizerSettings settings = gson.fromJson(preferences.getString(PREF_KEY, "{}"), EqualizerSettings.class);
        EqualizerModel model = new EqualizerModel();
        model.setEqualizerEnabled(settings.isEqualizerEnabled);
        model.setBassStrength(settings.bassStrength);
        model.setPresetPos(settings.presetPos);
        model.setReverbPreset(settings.reverbPreset);
        model.setSeekbarpos(settings.seekbarpos);

        Settings.isEqualizerEnabled = settings.isEqualizerEnabled;
        Settings.isEqualizerReloaded = true;
        Settings.bassStrength = settings.bassStrength;
        Settings.presetPos = settings.presetPos;
        Settings.reverbPreset = settings.reverbPreset;
        Settings.seekbarpos = settings.seekbarpos;
        Settings.equalizerModel = model;
    }

    private void saveEqualizerSettings(){
        if (Settings.equalizerModel != null){
            EqualizerSettings settings = new EqualizerSettings();
            settings.isEqualizerEnabled = Settings.equalizerModel.isEqualizerEnabled();
            settings.bassStrength = Settings.equalizerModel.getBassStrength();
            settings.presetPos = Settings.equalizerModel.getPresetPos();
            settings.reverbPreset = Settings.equalizerModel.getReverbPreset();
            settings.seekbarpos = Settings.equalizerModel.getSeekbarpos();

            SharedPreferences preferences = PreferenceManager.getDefaultSharedPreferences(this);

            Gson gson = new Gson();
            preferences.edit()
                    .putString(PREF_KEY, gson.toJson(settings))
                    .apply();
        }
    }

from above code you could notice i have added this line settings.isEqualizerEnabled = Settings.equalizerModel.isEqualizerEnabled(); instead of settings.isEqualizerEnabled = true; so that we have a extra function of enable and disable.

settings.java

public class EqualizerSettings {
    public boolean isEqualizerEnabled;
    public int[] seekbarpos = new int[5];
    public int presetPos;
    public short reverbPreset;
    public short bassStrength;
}

Can you help me what's wrong with my code?
There is a difference with the code, because i'm connecting Flutter with Java so the code must like that.
Thank you!

i am working on DJ Mixer app and in this i am using two object of equalizer (both are separate) but in some device only one equalizer is working and another is not working.

How do i add Dialog Equalizer with ExoPlayer.

As per your documentation i was able to add in equalizer in activity but i was not able to open in Dialog. And also i want to add with ExoPlayer

is there any brief documentation, to add equalizer with exoplayer and open in dialog.

Or how can we do that ?

Not working after canceling or dismissing dialog.

Equalizer works when dialog is opened but as soon as the dialog is closed the equalizer does not work, Is there any solution for this

Licence

If you build / used some code from https://github.com/harjot-oberai/MusicDNA as per your README:

This work is mostly borrowed from https://github.com/harjot-oberai/MusicDNA

then you should publish it under the same licence, as the MusicDNA is publish under BY NC SA licence (BY - attribution, NC - non-commercial, SA - share alike). You only fulfilled the BY part. SA means you should not publish your work under different license if it's based on MusicDNA's code.

Why it matters: I am building a commercial app and was looking for open source equalizer. I can use code under Apache/MIT licence and add link to the repo in my app, but I am (obviously) not allowed to use code under NC licence.
