View Full Version : Normalise Commentary?

Hi,

I've something with a few audio tracks most of which are commentary. Is there a way to use normalisation so that the commentaries don't sound incredibly loud and distorted?

P.S. I'm using linux so I think the program I've available to me is normalize-audio which has the following options;

-a, --amplitude=AMP normalize the volume to the target amplitude
AMP [default -12dBFS]
-b, --batch batch mode: get average of all levels, and
use one adjustment, based on the average
level, for all files
--clipping turn off limiter; do clipping instead
--fractions display levels as fractions of maximum
amplitude instead of decibels
-g, --gain=ADJ don't compute levels, just apply adjustment
ADJ to the files. Use the suffix "dB"
to indicate a gain in decibels.
-l, --limiter=LEV limit all samples above LEV [default -6dBFS]
-m, --mix mix mode: get average of all levels, and
normalize volume of each file to the
average
-n, --no-adjust compute and display the volume adjustment,
but don't apply it to any of the files
--peak adjust by peak level instead of using
loudness analysis
-q, --quiet quiet (decrease verbosity to zero)
-t, --average-threshold=T when computing average level, ignore any
levels more than T decibels from average
-T, --adjust-threshold=T don't bother applying any adjustment smaller
than T decibels
-v, --verbose increase verbosity
-w, --output-bitwidth=W force adjusted files to have W-bit samples

I would be interested what you have to say about normalising commentary in windows to. I just mentioned the program I'm using in case it was useful.

HI!I've something with a few audio tracks most of which are commentary.1) What is this "something"? Is it a DVD (If so, what is the Title and Region number?) or, if not, what then?

2) What is the audio format of the commentary tracks?

Uh huh, it's a DVD. However it's not a problem getting the DVD to copy I have each audio stream in wave files which I can normalise. It's more a general question about normalisation with streams that only contain speech.

it's a DVD.Do the commentary tracks on your original DVD also "sound incredibly loud and distorted"?

If so, what is the Title and Region number of the DVD?
If not, what was the original format of the audiostreams and what procedures did you use to extract and convert these audiostreams to .WAV format?

No the original commentary is fine as is the wav that's produced. It's just that if I normalise them they sound distorted. I have noticed before that if you normalise anything with only speech in it it sounds like this. I will probably just not normalise those tracks but they will be quite quiet in comparison to the main audio track which has been normalised.

:rolleyes:

That's so simple I would never have thought of it!
