vii. Audio sample rate is 44100Hz.
viii. Audio bit depth is 32-bit (float)
ix. Audio channels are in stereo format, which are Left and Right channels.
x. The audio quality is very low although it is hearable.
xi. Figure 4.2.3.4 is showing the Cepstrum view which is used for pitch determination/analysis.
xii. Figure 4.2.3.5 is showing 3D Fast Fourier Transform (3D FFT) is an algorithm that computes
the Discrete Fourier transform (DFT) of a sequence, or its inverse (IDFT).
xiii. Audio seems to be cut between time frame 1.24.2 and 1.24.3. Different frequency level
appears in many places and different background noises level were seen.
xiv. A new person voice was heard between 1:09.5 and 1:49.0 throughout this track instead of
Grek.
xv. A new person voice was heard between 1:09.5 and 1:49.0 throughout this track instead of
Major.

xii. Possible merging can be seen between 2:02.94 and 2:02.97, also sudden difference in the
spectrum frequency from 2:02:98.
xiii. Two different militants speaking in the track 5. But no information about this in the video.
xiv. Back noises were not heard only when Kozitsyn speaks background noise are heard.

Figure 4.4.1.2: A gap which appears at the end of third phrase ~0:32.6 uttered by V. Gernanin in the audio Track-1 (Left Channel) is possible indication
that Geranin voices are merged into the conversation. Audio spectral at 0:31.75 – 0:31.85 (Left Channel) showing added cut, paste and merger of other
sound in this audio.

103

Figure 4.4.1.4: Right Channel - It appears that the audio was cut down and merged at 0:23.20 from the end of a conversation. Different audio
conversation starts at 0:23.30. Left channel (arrow up-bottom) showing merging of audio at 0:23.43.

4.4.3 Audio 2, Track-3

Figure 4.4.3.1: In Audio 2, Track-3, background noises are not similar in this part from 0:58:75 and 0:59:0. At 0:58.85 another difference noise were seen.

107

4.4.4 Audio 2, Track-4

Figure 4.4.4.1: In Audio 2, Track-4 possible edits can be seen between 1:13:55 and 1:13:5 and between 1:15:20 and 1:16:20, background noise suddenly appears from nowhere completely unrelated to the speakers’ atmosphere.

4.4.5 Audio 3, Track

Figure 4.4.5.1: Audio 3 Track-5 begins from 1:50.2 and ends at 2:22.7. This segment of audio has 3 different individual voices, it appears to be two
different militants speaking to Kozitsyn. 2 Different audios in different channels. Cut of audio in Right channel at ~1:51.0 – 1:54.0, ~1:57.5-2:00.0,
~2:01.0-2:02.5, ~ 2:04.5-2:07.5 & ~2:10.5-2:12.0

113

Figure 4.4.5.3: Muffled and no background noise appears were seen between 1:50.2 and 1:53.6 (Right Channel). However, background noise appears
normal after 1:53.8 till the end of the track. Two different channels. Left Channel - (Arrow Up-Bottom) – adding of audio between ~2:12.6 and 2:14.2.
Right Channel (Arrow Up-Bottom) – merging ~2:12.3 until 2:22.28. This is clear editing/adding of audios
