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.
