Question

I have a audio wave file (*.wav) and I have the audio data formatted in signed 16-bit (from -32767 to +32768). I want to convert them in unsigned 16-bit (from 0 to +65535). Is there some idea how to do that using audacity, sox ot any other otol? Even a c programm is welcome.

Thanks

Solution

Add 32768 to each sample. Note that this is equivalent to inverting the MSB (most-significant bit) of each sample.

OTHER TIPS

In Audacity trying using the export command. (FILE - Export )
