Subject:Volume level, batch converting
Posted by: Svensson
Date:1/4/2001 10:41:00 AM

I want to know if there is any way to get multiple
soundtracks (speach) at the same level, say rms 14, by
using the batch converter.
I want the sounds exactly at the same level..
Yes I know, sf:s helpfiles says that this is not possible,
but maybe you guys have a clue.
Thanks.

You can use the Normalize command and check "Average RMS
Power" and then adjust the slider to -14dB. Unfortunately
I have never learned how to effectively use the batch
converter so I can't help you with that. Can someone give
me a step by step tutorial using the batch converter
to "normalize" multiple files? I've tried this in the past
and haven't quite figured it out yet.

Hello,

This is how to use the Batch Converter:

1. Open the Batch Converter from the tools menu in Sound
Forge.

2. Go to the options menu of Batch Converter and
select "Conversion Settings".

3. If you wish to convert the files to a different format,
put a check in the "File Format" checkbox. To apply a plug-
in, put a check mark in the "Use Plug-ins" box.

4. Change the file format to the desired format, or select
your class of plug-in. The classes are the same as the
menus across the top of the Sound Forge window. After you
have selected a class, select either a function or a preset.

5. After you have set your parameters the way you want
them, click on the plus sign (+) to the right of the
words "Batch Script". If you want to perform more than one
operation in one script, go back and select another plug-
in, making sure to click the plus sign when you are
finished.

6. After you have set up your script, click OK.

7. Go to the file menu and select "Add".

8. Click on the 'Destination' button in Batch Converter to
set up a directory to put the converted files into.

9. Click the 'convert' menu in Batch Converter and
select "Run Current Script" and Batch converter will take
care of all the files that have been added.

Thank you Ted, Now when I master an entire album I can
simultaneously normalize all the songs and walk away and go
get a beer.....uhhhmm.. I mean coffee, and come back and it
will be done.

I really don't see how anyone can make such a statement
as "maybe about only 5 lines of code" when that person has
not seen the source code and has no idea what algorythms
are involved in the process.

Its really easy to do "arm chair coding" but when it comes
down to really writing code its a different story.

And with version 5 on the horizion, why would SF spend a
lot of time and money on R&D for a product that will soon
be obsolete?

The documentation clearly says Noise Reduction will reduce
scratches, pops, hisses, and similar noise from vinyl
records. It does not say it will fix skips, jumps, or
build bridges over a gap ("large enough to insert a
business card into...") in the vinyl.

SF sells software not magic.

Thanks Dave,
With over 35 years experience on computer systems
software & hardware, starting in the old days of assembler
code, I have a pretty good gut feel about what is involved.
The "decimal positions fix" is a no brainer - just a change
in the C-code input format specifier - probably just one
line of code.

Thanks Dave,
With over 35 years experience on computer systems
software design and coding & hardware design, starting back
in the old days of assembler code, I have a pretty good
good gut feel about what is involved. The "decimal
positions fix" is a no brainer - just a change in the C-
code input format specifier - probably just one line of
code.
Anyway, SF5.0 Beta build 102 added 2 more decimal
positions (total 3), and now the problem is solved. Works
nearly perfectly.
Perhaps you need to be less snooty about tools others
besides yourself require. The level of heat expressed by
some professionals in the business, could alleviate the
energy crisis.
Thanks for your help.

We do have an audio plug-in developer kit on the website
should you want to tackle this on your own...

Thanks SonicEPM,
But you have already tackled it quite well in SF5 Beta.
The new "3 decimal precision" entry that you changed to in
the SPECIAL/EDIT TEMPO, "FREQUENCY of events" parameter,
solved the original bug/problem very nicely, just as I
originally recommended to you.
Don't know why others on the forum complain about S.F.
not listening to its customers - eventually Sonic Foundry
does get the point, and I appreciate that. Just requires
persistence in getting oneself understood, I guess.
Cheers
