3. Navigate to the (.wav) file that you want to authenticate and select the file. Click the
Open button (Fig. 2.). One of three results will display: Unmodified (Fig. 3.), Unmodified but
date/time not correct (Fig. 4.), or Audio data modified (Fig. 5.).
The result shown in Figure 3 indicates that the file is trustworthy.
In the example in Figure 4, the audio was not modified, but the time and/or date information
contained inside the .wav file does not agree with the file’s date/time stamp, indicating that it
may have been tampered with.
In the Figure 5 example, the wave file audio has itself been modified and cannot be trusted.
Fig. 3. Result: Unmodified wave file. Fig. 4. Result: Unmodified wave file but
