Question

Sudden drop in frequency of a music video

Hi, I'm a new user of Audition CC 2015. I have a video recording of a concert that I took with my video cam and saved on an SD card. The first 15 minutes were perfect and then all of a sudden I got a drop in the frequency level (see attached image). I've been trying to fix it using Audition CC 2015, I tried researching and finding a solution with no much success. Can someone point me in the right direction or things that I should try to do in order to fix this?

Thank you! Much appreciated,

JP

I think this will work, but the chances of fully restoring the audio to match that of the first section are pretty slim.

If you highlight the whole of the quiet section and then use the on-screen "volume" control - it's there on your picture, on top of the "loud" section - to increase the level, that will produce some increase in volume and noise.  Looking at the frequency spectrum display, my suspicion is that a lot of what has been recorded is noise, but you may be lucky.

You ought also to be concerned as to why this happened.  Looking at the levels on the loud section, which are almost certainly clipping quite extensively, I think, it's almost as if your camera's audio AGC (automatic gain control) has completely ceased working due to (?)overload.

    The original says 'fall in frequency' and looking at the RHS of the spectral display, it certainly seems like it. For the life of me, I can't imagine how it could have got like that though; that's not what cameras do.

    It would be easier to come up with a more definitive answer if we could have a copy of the actual audio...
