Batch loudness converter script

[chmaha]

I hope that this is useful for peeps who need to normalize audio files either before entering the DAW or for distribution afterwards:

https://github.com/ElizabethHarmon/ebu-norm

**NEW**
v2.2 released:
https://github.com/ElizabethHarmon/e...eases/tag/v2.2

Release includes:
ebu-norm -- normalizes to -23 LUFS integrated by default but allows for custom targets with -t flag. Uses sound-gambit for true-peak limiting as needed.
tp-norm -- normalizes to -1 dBTP by default but allows for custom targets with -t flag
ebu-scan -- analyzes audio files and produces formatted output to both screen and loudness_analysis.txt.
ebu-plot (alpha) -- (batch) create loudness graphs in PNG format. e.g. https://user-images.githubuserconten...bdc5b154fe.png

Deprecated scripts:

sox-norm -- ebu-norm but using a 4x compand chain
loudmax-norm -- ebu-norm but using the Loudmax true peak limiter (https://loudmax.blogspot.com/)
lsp-norm -- ebu-norm but using the LSP true peak limiter (https://lsp-plug.in/)

**NEW** v0.3 includes a limiter function for positive gain instances that push true peaks beyond -1dBTP, verbose output showing filename and applied gain/limiting, and a separate dbtp-norm script for batch normalizing to true peak values.

Very Useful thx

Great! FYI, I pushed a few updates so latest version is 0.3.1. Hopefully later today I will add a second analysis pass after limiter to hit integrated values precisely.

Significant additions/improvements so bumping the thread. Up-to-date info in the top post.

Hi friends.
Thanks in advance. For the tool and the effort that for sure involve and also for the help.

Could be possible a kindly explanation that how could I do this tool work?

I downloaded de .zip with all the elements from here>> https://github.com/ElizabethHarmon/e...ses/tag/v2.0.1

I unziped it, executed the Install file, but from this point I can't find the tool.

Sorry for my ignorance but I need some help.



Cheers from Spain.

Hi!

If you ran the install script it should install stuff into /usr/local/bin.

You should then be able to run the scripts from any directory in the terminal (assuming typical PATH values)...Does that help at all? You can run ebu-norm, tp-norm or ebu-scan either with single or multiple files...With no flags default values are used, otherwise use the -t flag (target) and then a numerical value (like -16) as per the readme.md: https://github.com/ElizabethHarmon/ebu-norm#readme.

Likewise ebu-plot can be run on single or multiple files but requires a few more dependencies (including the evil powershell) until I get around to making it pure bash.

Ohhh. Really thanks Elisabeth, I'll dive on It tomorrow. The last time I didn't be able ti find the Bin directory, But sure was my fail. I'll try again.

Really thanks for your time and effort on this tool, and of course for sharing.

Hugs.

You are most welcome!

Hopefully you don't need to "find" /usr/local/bin. In most distributions, you should be able to run the scripts from anywhere. Let me know if you have any other questions!

v2.2 released which mainly updates sound-gambit filename reference in install.sh for pulling latest binary from github.
