FFMPEG sound-Week 13

This ffmpeg tutorial was great in order to capture just the audio from a video into different formats.

Here is my shell history:
66 ffmpeg
67 ffmpg -i twosides.VOB tsaudio.mp3
68 ffmpeg -i twosides.VOB tsaudio.mp3
69 ls
70 cd Test 2
71 ffmpeg -i twosides.VOB tsaudio.mp3
72 cd Test2
73 cd ..
74 l
75 ls
76 cd Test2
77 ls
78 ffmpeg -i twosides.VOB tsaudio.mp3
79 ls
80 mplayer tsaudio.mp3
81 ffplay tsaudio.mp3
82 ls
83 history > ffmepgsound1.txt

84 ls
85 ffmpeg -i twosides.VOB tsaudio.wav
86 ffplay tsaudio.wav
87 ffplay tsaudio.wav
88 ffplay tsaudio.wav

So basically what I accomplished with this tutorial was taking the captured audio and playing it with ffplay.
This is the website that told me ffplay existed as an audio player. http://howto-pages.org/ffmpeg/ This will be very handy in the future. I played the wav file of this audio so many times because I wanted to demonstrate in this post how a visual representation of my voice was displayed in the audio dialog box that popped up when I played the audio.

 

The black spaces represent when audio is absent and the white shapes represent my voice-over narration and any ambient sound or sound effects from my film, Two Sides of One Coin.

But the really fascinating quality of this discovery was that when I edited the audio for my film originally, there was a part in which I split the audio into two parts, to illustrate the two sides of one coin theme. When I listened to this part of the audio, I noticed that the vioce-over narration was showing up visually as magenta in the foreground and green in the background where white had been previously. It was showing visually and through opposite colors that I had split the audio into opposite parts.
