我想比较两个音频文件,所以我正在使用库musicg。但我得到一个错误“WaveHeader:只支持bitsPerSample 8或16”

代码:

String root = getExternalFilesDir(null).toString();
Log.i(TAG, root);

String bell1 = "bell1.wav";
String bell2 = "DOORBELL-3_SPLITTED.wav";
String fullPath1 = root + File.separator + bell1;               
String fullPath2 = root + File.separator + bell2;               

Log.i(TAG, "Full Path 1: " + fullPath1);
Log.i(TAG, "Full Path 2: " + fullPath2);

File f = new File(fullPath2);
Log.i(TAG, "" + f.canRead());

Wave b1 = new Wave(fullPath1);
Wave b2 = new Wave(fullPath2);

我收到了以下错误。
