- I have one DVD from 1999 and the other one from 2003, which vocal removing equipment\software or something did they used to remove the vocals to make stereo to 5.1 audio in this technique?
26.75 MB folder on MEGA Here 5.1 clips from my DVDs - What if I digitized VHS and wanted to turn them to 5.1 audio using the same technique used in my audio clips but the VHS audio is centered?
Thanks!
Are you sure they didn’t make a new 5.1 mix from the original multitrack recording? I believe that’s how it’s usually done.
Your AVR should have several Pro-Logic “soundfield” or “upmixing” settings and this is often the easiest and best way to convert stereo to surround. I like to use a “hall” or “theater” setting with regular stereo music. But I don’t think they will work well with your mono (“centered”) VHS audio.
There is a new AI Music Separation plug-in for Audacity but I haven’t tried it. There are other AI un-mixing/separation tools and AI is getting smarter every day!
…Once or twice, I made a surround recording from a mono video concert. For the front I used EQ to get center, left, and right. I put most of the vocal/midrange in the center and I kept the extreme highs & lows in both the left & right so it didn’t terrible or obviously “fake”. Plus, you usually want “mono” bass to get the most from both woofers. (Note that the “complement” of an infinite cut, is +6dB, so if you cut by 6dB in on channel and boost by 6dB in the other channel, they don’t mix-back “flat”. And you can’t generally boost at all without making an overall downward adjustment or you’ll (usually get clipping).
For the rear I used used delay and reverb, and again I used EQ to get different sound in the left & right rear.
If you have stereo, you can use the regular center-channel vocal remover effect on the rear channels but that won’t work with mono.
During talking between songs, I panned the sound to the center.
I copied applause from different parts of the recording and mixed it into the rear so the applause in the two rear speakers was truly different from the original remaining in the front.
I created the “point one” channel by low-passing and then pitch-shifting down one octave. …You’re not supposed to do that! The point one channel is supposed to be the LFE (low frequency effects) channel and the regular/musical bass should be in the other channels. Then your AVR has “bass management” to re-route all of the bass to your sub if your main speakers can’t reproduce the full-range bass.
I’m not sure if they had the original multitrack recording, these DVD pressings are not official.
