equalizer #

A Flutter plugin to open the device equalizer. You can also create a custom equalizer for Android.

Currently, supported on Android only. Need help for iOS contributions.

Example

Android Setup #

Edit your project's AndroidManifest.xml file to declare the permission to modify audio settings when creating a custom equalizer.

<manifest>
    <uses-permission android:name="android.permission.MODIFY_AUDIO_SETTINGS" />
    <application...>
    
    ...
    </application...>
</manifest>

Example #

// Import package
import 'package:equalizer/equalizer.dart';

// Open device equalizer
Equalizer.open(audioSessionId);

// Set or remove audioSessionId.
Equalizer.setAudioSessionId(audioSessionId);
Equalizer.removeAudioSessionId(audioSessionId);

You can retrieve audioSessionId on android from MediaPlayer. Info on how to do this can be found in openEqualizer docs.

Custom Equalizer Example #

Initialize the equalizer. Recommended to perform inside initState

Equalizer.init(audioSessionId);

Enable the equalizer as follows.

Equalizer.setEnabled(true);

Now you can query the methods.

await Equalizer.getBandLevelRange(); // provides band level range in dB.

await Equalizer.getBandLevel(bandId);
Equalizer.setBandLevel(bandId,bandLevel);

await Equalizer.getCenterBandFreqs(); // provides the center freqs in milliHertz.

await Equalizer.getPresetNames(); // returns presets that are available on device
Equalizer.setPreset(presetName);

Finally, remember to release resources. Recommended to perform inside dispose

Equalizer.release();

  • Add iOS support.
