Answer 1

Try FFmpegMediaMetadataRetriever:

String[] fileNames = ...
FFmpegMediaMetadataRetriever mmr = new FFmpegMediaMetadataRetriever();

for (String fileName : fileNames) {
    AssetFileDescriptor d = context.getAssets().openFd(fileName);
    mmr.setDataSource(d.getFileDescriptor(), d.getStartOffset(), d.getLength());
    String duration = mmr.extractMetadata(FFmpegMediaMetadataRetriever.METADATA_KEY_DURATION);
}

mmr.release();

Answer 2

Did you try this:

String mediaPath = Uri.parse("android.resource://<your-package-name>/raw/filename").getPath();
MediaMetadataRetriever mmr = new MediaMetadataRetriever();
mmr.setDataSource(mediaPath);
String duration = mmr.extractMetadata(MediaMetadataRetriever.METADATA_KEY_DURATION);
mmr.release();

But i am not exactly sure that this is lighter than exisiting code.

this is work for me to get assets audio file duration in total seconds=====>

MediaMetadataRetriever mmr = new MediaMetadataRetriever();
AssetFileDescriptor d = context.getAssets().openFd(fileName);
mmr.setDataSource(d.getFileDescriptor(), d.getStartOffset(), d.getLength());
String duration = 
mmr.extractMetadata(MediaMetadataRetriever.METADATA_KEY_DURATION);
mmr.release();

method to get assets audio file duration in seconds

  public String gettotaltimeassets() {

   MediaMetadataRetriever mmr = new MediaMetadataRetriever();
    AssetFileDescriptor d = null;
    try {
        d = getApplicationContext().getAssets().openFd("ASSETS FILE NAME");
    } catch (IOException e) {
        e.printStackTrace();
    }
    mmr.setDataSource(d.getFileDescriptor(), d.getStartOffset(), d.getLength());
    String duration = mmr.extractMetadata(MediaMetadataRetriever.METADATA_KEY_DURATION);
    long dur = Long.parseLong(duration);
    String seconds = String.valueOf((dur % 60000) / 1000);
    Log.d("seconds===========>", seconds);
    mmr.release();
    return  seconds;
}

method to get internal storage audio file duration in seconds

public String gettotaltimestorage(String filePath) {
    // load data file
    Log.d("time=================>","time=================>");
    MediaMetadataRetriever metaRetriever = new MediaMetadataRetriever();
    metaRetriever.setDataSource(YourACTIVITY.this, Uri.parse(filePath));
    Log.d("time=================>","time=================>");
    String out = "";
    // get mp3 info

    // convert duration to minute:seconds
    String duration =
            metaRetriever.extractMetadata(MediaMetadataRetriever.METADATA_KEY_DURATION);
    Log.d("time=================>", duration);
    long dur = Long.parseLong(duration);
    String seconds = String.valueOf((dur % 60000) / 1000);
    Log.d("seconds===========>", seconds);
    // close object
    metaRetriever.release();
    return  seconds;

}
