Topic: Normalize 24 bit source (5 gig file)

[hoyt]

Im Interested in hearing your RRFB show. My recording sounds like I had the "tin can" switch on. 
Is that what your working on by chance?

Yup, that's what I'm working on.  It's been sitting on my hdd too long.  It doesn't sound great, but I applied a bit of a compressor to bring it all out a bit more.  Should start uploading it to the archive later tonight.  That minute long feedback section sucks - if RR hadn't kept playing I could cut it out, but he's playing the whole time of that squeal so I'm leaving it in with a note in the text.

EDIT:  Oops, by using Audition's mix down function it looks like it automatically made the output a 16 bit file.  Is there anyway to avoid this?  There's no mention of this in the Audition help files, maybe my version is just old?  (1.0 Build 3180)

Double EDIT: So, there's a setting that I didn't know about that I found on the Adobe Audition forums... Options > Settings > Multitrack > Mixdowns, and I can set 32 there.  Okidoki.  I think I'm set this time!

with traditional normalization, audio progs scan a file for the loudest peak and amplifies so that the peak attains the loudest level.
 but if you do it while mastering, the songs will still vary in level because our ears respond to a songs "average" level. Metanormalize(wavelab tool) normalizes using RMS(average levels)


WAVELAB:

drag all the files into the main window.
select batch process from the tools menu
click on the input tab, then add file button in the batch processing window, then select ADD ALL.
click on the edit batch plug ins button, when the processor list appears open the plug ins folder, and double click the Meta Normalizer plugin.

after clicking on the meta normalizing plugin, it appears in the left column in the processor list. double click to show the meta normalizer parameters , click on "equalize loudness"(RMS) "check global"(check maximize if possible if you want to use every bit of headroom)then check ok.

click on the processor list OK button
click on the batch process output tab. Click on the folder button to navigate to the desired folder, or create a new one. click on RUN and the files will be metanormalized and deposited where you want...

But how do you do any "post" on a 24 bit file then?

This is one of the reasons I use Adobe Audition instead - it doesn't choke on > 2GB files.  It's a little slower processing, but saves the hassle of manipulating multiple files.

Doesn't Audition choke at 4GB? If his is 5GB then he is still SOL. I'd add them all in Wavelab, find your peak, then add gain to each file as mentioned earlier. Hopefully Wavelab 6 shows up soon to see how it handles this mess.

Nope, at least not for me running Audition 1.5 and an NTFS partition.  Just normalized, resampled, and dithered a 5GB 24/48 file down to 16/44 with no problems.

+T Teddy.  I've been wondering how to do an RMS normalize in Wavelab for quite a while.  Thanks.   Wavelab is much more confusing to me than Soundforge...
