Hey guys… thanks for all the replies and interest.
I’ve raised this topic, so I’ll do the best I can to provide the info required to understand what is happening.
To this end, I’ve uploaded 4 files to google drive regarding two audio files (before & after for each).
One pair is a successful implementation of Audacity filters/effects the other is a partial success (why… I don’t know.
You can use your ears, and if downloaded your eyes, to figure the problem and any potential solution.
The first thing to say is: that on the initial modded file… the results were as stated - original awful; modded ‘highly acceptable’.
re: kozikowski : making it louder - you may be right, but my ears told me different because the ‘noise’ actually reduced… judge for yourself below.
re: DVDdoug : soundcards - understood, but it was just crap, and then after Amplify, it was better… on the same sys.
re NR - the main gain was with amplify - the other mods were specific to areas (and good), but the primary problem was ‘within the actual voice (speaking) audio’ so, hard to isolate - examples below.
re win 7/8: noise & shite vis a vis camera mic’s: This kit is very good on XP (impressive and no sound probs) - I’m not a noob with PC’s… been working with them since IBM DOS… I complained bitterly to Logitech over a year ago re shite win 7 install fail - they produced another (not tested on win 7 yet) but win 8 install was bizarrely as described… literally: each install got better(???) but it was still crap - written in stone - examples below.
re: downloading from youtube, something I produced… very fair point; and it played on my mind… the knowledge of disappearing in a fog of noise… however, I ask forgiveness:
The sob story: The audio describes methodology relating to a win 7> prog… so I couldn’t conduct it on my XP box (it was ‘show & talk’).
My win 7 box is underpowered and anyway has XP camera code (not great) so I turned to my win 8 box, and you know the story there.
It was 3.00 am when the vid was done, so I uploaded it to youtube with youtube merge edits ie. it was a finished video lacking only a couple of text panels(introduction, and thanks for watching etc).
The problem this morning was the audio, and how to fix it… should I start again, editing with VSDC, or sort the audio problem… I went with the latter, and downloaded the combined video and audio track.
I have the original clips, so it doesn’t matter (I can rebuild the vid from original source)… the key is to fix the audio.
So yes, I accept the ‘copy noise’ problem, but honestly, this is not the issue (and neither is the sound studio, because I’m comparing this to very many XP produced vids).
But I accept all your points are otherwise valid.
re kozikowski 2nd post - I accept the good advice, but we are dealing with something far worse.
The upload / download lossy issues were imperceptible.
The overriding issues are the gains from amplification, and the failure to make similar gains with the 2nd video (though improvement was seen).
Here are the files:
I have re-done both originals with purely ‘amplify’ and cut a short section.
You will hear the terrible audio in the originals… and the genuine improvement after amplification.
What do you think?
