I recently bought a bluray for an old movie and nearly all of the 6 channels have been run through a low-pass filter, center channel especially so. Now, I realize that clipped audio cannot be restored however is there a way to algorithmically generate the clipped high frequencies to a certain degree to mitigate the effects of the audio sounding "covered up"?
It's not a really old movie actually (2005). The thing is that the bluray is a remastered version of a film that was done by REM. It has two audio tracks, German and Hindi in dts-hd ma. Now, the German audio is perfect as well as the songs (which they kept intact in the hindi) however, the hindi track of the film sounds like it did with the original DVD release. Deep hum sound. Almost like I'm hearing it from another room. I'm not sure if that's clipping or something else.
Although it's not a topic of this thread, I'm quite interested to know how REM managed to work with the original hindi track and fix it to near pristine audio fidelity for use in the German track. Did they have a different source to work from altogether? My main goal here is to replace the German track's center channel with the Hindi track's center channel yet use all of the channels in the song portions of the German track.
Two issues with this:
1. If I cannot manage to get the Hindi center track to match the audible frequencies of the German track's side and back channels then the final mix will sound odd and the whole process will be moot.
2. I'll have to find the parts of the audio in which the dialog delivered has an echo effect which permeates through the side and back channels. In those parts I'll have to use the affected channels (probably all) from the hindi track and apply the same fix to those channels as done to the center channel.
Here are 1min and 2min 30sec cuts of the same time frames from the center channels of both language tracks: https://www.dropbox.com/s/lglh21tsa1k57pj/comparison.zip https://www.dropbox.com/s/vj2ccxzjh1wdnzn/comparison_2.7z
Honestly, I'm not sure where to begin. The german audio sounds like it was recorded and mastered entirely differently.
Thanks in advance.
