I stumbled on the answer (frankly, by trying &^@! I didn’t think would work), in case anybody’s interested… In my original code (which is derived from the example in the link in the original post), the data is read from the file like so:
InputStream is = new FileInputStream (file);
BufferedInputStream bis = new BufferedInputStream (is, 8000);
DataInputStream dis = new DataInputStream (bis); // Create a DataInputStream to read the audio data from the saved file
int i = 0; // Read the file into the "music" array
while (dis.available() > 0)
{
music[i] = dis.readShort(); // This assignment does not reverse the order
i++;
}
dis.close(); // Close the input stream
In this version, music[] is array of SHORTS. So, the readShort() method would seem to make sense here, since the data is 16-bit PCM… However, on the Android that seems to be the problem. I changed that code to the following:
music=new byte[(int) file.length()];//size & length of the file
InputStream is = new FileInputStream (file);
BufferedInputStream bis = new BufferedInputStream (is, 8000);
DataInputStream dis = new DataInputStream (bis); // Create a DataInputStream to read the audio data from the saved file
int i = 0; // Read the file into the "music" array
while (dis.available() > 0)
{
music[i] = dis.readByte(); // This assignment does not reverse the order
i++;
}
dis.close(); // Close the input stream
In this version, music[] is an array of BYTES. I’m still telling the AudioTrack that it’s 16-bit PCM data, and my Android doesn’t seem to have a problem with writing an array of bytes into an AudioTrack thus configured… Anyway, it finally sounds right, so if anyone else wants to play Windows sounds on their Android, for some reason, that’s the solution. Ah, Endianness……
