Using Audiorecord With 8-bit Encoding In Android

I have made an application that records from the phones microphone using the AudioRecord and 16-bit encoding, and I am able to playback the recording. For some compatibility reason

Solution 1:

If you look at the source, it only supports little endian, but Android is writing out big endian. So you have to convert to little endian and then 8-bit. This worked for me and you can probably combine the two:

for (int i = 0; (offset + i + 1) < bytes.length; i += 2) {
    lens[i] = bytes[offset + i + 1];
    lens[i + 1] = bytes[offset + i];
}
for (int i = 1, j = 0; i < length; i += 2, j++) {
    lens[j] = lens[i];
}

Here is a simpler version without endian

for (int i = 0, j = 0; (offset + i) < bytes.length; i += 2, j++) {
    lens[j] = bytes[offset + i];
}
