Batch save tracks with meta data after normalization

Audacity 3 Help Forum
1

I suspect that a) this has been asked before and b) the answer seems to be no.

I am trying to find a way to normalize my wav file collection. Apparently, with Audacity, when I try to save (export) all the tracks in a project as songs, all songs’ meta data is the same. I sure hope that there is a way to export all tracks to files with meta data?

I’m not sure, but I’m sure you’ll lose any embedded artwork because Audacity doesn’t support embedded artwwork…

…If you want to loudness normalize rather than peak normalize, WAVGAIN can be found here. It should be easier and faster and It shouldn’t touch your metadata.

And it’s got an advantage over Audacity’s Loudness Normalization in-that it won’t over-boost into clipping. It will just give you an LUFS loudness lower than otherwise.

What an incredibly useful link.

Do you know of a “rare wares” site for video data?

I’ve been looking for a signed copy of the old NMKODER package (one that targets file size), so my computer won’t quarantine it every time I run it.

Sorry, no.

VideoHelp.com has lots of video related information and links, but if NMKODER was there I’m sure Google would have found it.

AfterDawn.com has some interesting stuff too.

I have XMedia Recode which can do all kinds of audio & video conversions with some optional “processing”.

one that targets file size

I assume you know that file size is directly related to bitrate (kbps or usually Mbps with video). kbps is kilobits per second and since there are 8 bits in a byte, divide by 8 to get kilobytes per second. With A/V files it’s simply the combined audio & video bitrates. (I made a spreadsheet to make everything easier, including minutes and hours conversions.)

I didn’t want to write a program, when one already exists, albeit an old one.

If DOS could do accurate floating point arithmetic I would have already created a script to generate an FFMPEG command to do the file reduction. It looks like I’m going to have to write and compile an executable.
