Lightweight audiowave progressbar for Android

Last update: Jan 5, 2023

Overview

Audiogram

Super lightweight audiowave progressbar written in Kotlin

Getting started

Add to your root build.gradle:

allprojects {
	repositories {
	    ...
	    maven { url "https://jitpack.io" }
	}
}

Add the dependency:

dependencies {
  implementation 'com.github.alxrm:audiowave-progressbar:0.9.2'
}

Attrs

attr	format	description
waveColor	color	with this color chunks will be filled
chunkWidth	dimension	every chunk will have this width
chunkHeight	dimension	maximum height all the chunks can be
minChunkHeight	dimension	minimum height all the chunks can be
chunkSpacing	dimension	spacing between chunks
chunkRadius	dimension	how much corners of every chunk will be rounded
progress	float	should be 0..100, it's float so you can easily animate this
animateExpansion	boolean	toggle the animated expansion
touchable	boolean	toggle to use it as a seekbar, default value is `true`

Note: If you are going to place this in a RecyclerView item, you have to set animateExpansion to false, otherwise you'll see an incredibly laggy scroll (check out the example)

In code

Settle the wave somewhere in your XML like this:

<rm.com.audiowave.AudioWaveView
    android:id="@+id/wave"
    android:layout_width="match_parent"
    android:layout_height="32dp"
    android:layout_margin="16dp"
    app:animateExpansion="false"
    app:chunkWidth="3dp"
    app:chunkHeight="24dp"
    app:minChunkHeight="2dp"
    app:chunkSpacing="1dp"
    app:chunkRadius="1dp"
    app:touchable="true"
    app:waveColor="@android:color/white"
    />

API

Set raw byte array asynchronously

// does downsampling in O(N) and shows the animation you see in a gif above (the inflation-like one)
setRawData(byte[] data);

// you also have the ability to listen, when does the downsampling complete
setRawData(byte[] data, OnSamplingListener callback);

In case you have a scaled byte array you want to draw, i. e. an array whose size is the amount of chunks to draw

// instantly redraws the wave without async downsampling process
setScaledData(byte[] scaledData);

You can use it like a Seekbar, it reacts on touches, just attach listener

wave.setOnProgressListener(OnProgressListener listener);

Note: that setOnProgressListener is a Java style API and with Kotlin you have to set it like this:

wave.onProgressListener = object : OnProgressListener {...}

This listener has 3 methods like a built-in Seekbar

void onStartTracking(float progress) {
  // invokes when user touches the view
}

void onStopTracking(float progress) {
  // invokes when user releases the touch
}

void onProgressChanged(float progress, boolean byUser) {
  // invokes every time the progress's been changed
}

Kotlin users can listen Seekbar event in a more convenient and clean way with properties:

wave.onStopTracking = {
  Log.d("wave", "Progress set: $it")
}

wave.onStartTracking = {
  Log.d("wave", "Started tracking from: $it")
}

wave.onProgressChanged = {progress, byUser ->
  Log.d("wave", "Progress set: $progress, and it's $byUser that user did this")
}

Contribution

There are some features(like better precision) I am about to implement, but a little bit later. If you'd like to help, you are always free to send pull requests or issues if you only want to suggest something

Progress bar not animating

Hello,

I tried running this in an application and for whatever reason I can't get the progress bar to animate up. It just stays flat. I have checked the bytes, and things look good. I even tried the static bytes array in your sample app with no prevail. Thank you!

Here is my code ` mBeatWaveFormIV.setRawData(getByte(mAudioFile.getAbsolutePath()), new OnSamplingListener() { @Override public void onComplete() { Log.d("audio", "Completed"); } });

private byte[] getByte(String path) { byte[] getBytes = {}; try { File file = new File(path); getBytes = new byte[(int) file.length()]; InputStream is = new FileInputStream(file); is.read(getBytes); is.close(); } catch (FileNotFoundException e) { e.printStackTrace(); } catch (IOException e) { e.printStackTrace(); } Log.d("Bytes", getBytes.length+""); return getBytes; }

Not available the setOnProgressListener

Hi, thank you for your good library. I'm having a problem, I added AudioWaveView and working properly, but unfortunately, setOnProgressListener is not found for me.

In fact, this interface does not exist. Please check and correct. Thank .

The waves doesn't match the sound?

I'm getting bytes with this style;

`byte[] soundBytes = null;

            try {
                InputStream inputStream =
                        getContentResolver().openInputStream(Uri.fromFile(new File(suanki_playlist.get(id).path)));

                soundBytes = new byte[inputStream.available()];
                soundBytes = toByteArray(inputStream);
            } catch (FileNotFoundException e) {
                e.printStackTrace();
            } catch (IOException e) {
                e.printStackTrace();
            }

            seekbar2.setRawData(soundBytes);`

Is it the problem?

can i make as flat

i mean like LED- or LCD-like bar gauge control for iOS https://github.com/ChiefPilot/F3BarGauge https://github.com/ChiefPilot/F3BarGauge

Fix code style.

My eyes hurt when I saw it, so I fixed.

Also a question, wouldn't it be better to use @JvmOverloads on AudioWaveView and replace inflateAttrs with init?

synchronizing audigram with mediaplayer

hey man , thanks for your awesome library . i have implemented my player and im getting the mp3 file by url and then i convert it to ByteArray and use audioWave.setOnProgressListener(...); . but when i implement it like seekbar i encounter with some problems , here is my code :

public class Mp3PageFragment extends Fragment {

    private View rootView;
    private MediaPlayer mediaPlayer;
    private SeekBar seekBar;

        @Override

                int mCurrentPosition = mediaPlayer.getCurrentPosition() / 1000;
                audioWaveView.setProgress(mCurrentPosition);
                currentTime.setText(formatDuration(mediaPlayer.getCurrentPosition()));

            });
        }
    }

}

every Thing works fine But As you can see i implement audioWaveView.setProgress(mediaPlayer.getCurrentPosition()); into the class timer to show streaming process but it makes this error :

and i think the problem is for audioWaveView.setProgress(); this method accept numbers between 0 to 100 but themediaPlayer.getCurrentPosition() is returning outranged number . in seekbar there was a method called : seekbar.setMax(MediaPlayer.getDuration()), but there is no such thing in your library , can you please tell me how to change that accepted number dynamically for set process ? Thanks <3

Wave background color is not updating

I'm trying to change the color of the bar after audio is played. After the audio played, filled color is changed successfully but the background color is not changing to the new color. Here's a code snippet:

            waveView.setOnProgressListener(new OnProgressListener() {
                @Override
                public void onStartTracking(float v) {

                }

                @Override
                public void onStopTracking(float v) {

                }

                @Override
                public void onProgressChanged(float v, boolean b) {
                    if (v == 100F)
                        waveView.setWaveColor(ContextCompat.getColor(itemView.getContext(), R.color.subtitleGray));
                }
            });

XML:

        <rm.com.audiowave.AudioWaveView
            android:id="@+id/wave"
            android:layout_width="match_parent"
            android:layout_height="28dp"
            android:layout_marginEnd="20dp"
            app:animateExpansion="false"
            app:chunkWidth="3dp"
            app:chunkHeight="28dp"
            app:minChunkHeight="2dp"
            app:chunkSpacing="1dp"
            app:chunkRadius="2dp"
            app:waveColor="#ef4f35" />

Tested on Moto G with 7.1.2. Any fixes/workaround is appreciated!

Don't know to convert to data type to use setRawwData() function

I figured out that this lib only supports .wav, but when we use a correct param, we can also draw the wave. But the dataType I receive from server is a JSON like: "["0.01", "0.03", "0.02",....]" and I cannot convert to ByteArray type that the function need. Do we need to do any further step, since I can convert it to FloatArray, and then ByteArray, but turn out it shows wrong waves.

AudioWaveView inside ScrollView

Hey @alxrm , Thanks for this library. but i have a query. Right now i think the width of Audiowaves are confined to the width of parent layout. i want to add it inside a scrollview so that it takes as much width it needs and i should be able to scroll. is there an easy way to do this or need to modify the library code?

Slow and excess load on the UI thread

Hello . I used WaveView inside the RecyclerView and found it to be extremely slow and adds extra load on the UI thread.

Please fix this problem. Thank .

setData :

   if (itemView.wave_voice.scaledData.isEmpty()) {
            Observable.fromCallable { fileHelper.getFileByte(voice.file) }
                    .newThread()
                    .subscribe {
                        itemView.wave_voice.scaledData = it
                        itemView.wave_voice.setRawData(it)
                    }
        }

func :

 fun getFileByte(filename: String): ByteArray {
        val file = getFilePath(filename)
        return if (file.exists())
            file.readBytes()
        else byteArrayOf(0)
    }

Not displaying correct audio wave on oreo, nougat and marshmallow

Unfortunately this library does not give correct audio wave on marshmallow, nougat and oreo. When I input a file of length 2 seconds and sound starts at 0:00 and ends at 00:01, rest seconds are blank.. then the audio wave shows no blank moments. Instead it shouw as if the there was sound during the whole recording.

How Detect Correct Raw Data?

Hi i record voice in telegram and final wave form is like following image

but when i used from this audio for test app the result was like this!

my code is

byte[] soundBytes = null;
try {
    InputStream inputStream = getApplicationContext().getResources().openRawResource(R.raw.f);
    soundBytes = new byte[inputStream.available()];
    soundBytes = toByteArray(inputStream);
} catch (FileNotFoundException e) {
    e.printStackTrace();
} catch (IOException e) {
    e.printStackTrace();
}
waveView.setWaveColor(Color.parseColor("#007fff"));
waveView.setScaledData(soundBytes);
waveView.setRawData(soundBytes, new OnSamplingListener() {
    @Override
    public void onComplete() {
    }
});

[REQUEST] Optional alpha channel

Hi, I'm using this library for a personal project where I place the progressbar between an image and a panel, with the default alpha channel it doesn't look very fine. I suggest accepting parameters for the not filled bars color, for the filled bars color and also for the alpha channel instead of using a hardcoded alpha value.

Animation in RecyclerView

Thanks for this project. I use this in recyclerview, and start progressAnim, there is some problem I think that caused by reuse with recyclerview. For example, the first items wave progress will be set for three or four items. How can I deal with it? Thanks

given array of bytes

Hi Thank you for the great library. I wonder where I can find the required array of bytes that I must pass to setRawData(), if I want to play a mp3 file. should I get file input stream and then get the byte array? I tried to do that but the created waves were not Compatible with the voice.
