Normalization vs Loudness Normalization in Audacity for ACX Audiobooks

[@JoeyTwentyTwo]

Learning a lot, but would have been nice to have more of an explanation on the differences between normalization and loudness normalization :)

[@a089300]

I second this opinion!

[@kreankorm]

You have just saved me hours of re-recording. Thank you, sir.

Thank you good sir, I am a beginner and your latest subscriber. Looking forward to gaining better skills at using this Amazing AUDACITY 3.5 free software! Much appreciation Cheers from Western Australia

Helpful. I'm pretty new and found that Audacity also has RMS normalize. As newbie still working on when each of the three is applicable. All named the same word throws me 🙂

Thank you, thank you, thank you! I've been having so much trouble with this, and now you've shown me how to fix it. Subbed.

I think this video just saved my life :) I received 55 narration file from a professional narrator for my children's book and also 55 files of a few seconds of music to put in front of each chapter from a composer. The music was over the Audible RMS limit and the narration was under. I learned how to alter the RMS but even when I set it to the lowest of -23, the peaks are often too high and the noise floor too low. I described it as a seven foot man trying to walk through a six foot doorway. I was worried the only way to fix it would be to go to every single peak in the six hours of audio and limit them. But using the peak limiter here seems like it will work. Just subbed to your channel. Do you have an 'Audacity for absolute beginners' video series? *EDIT: Just tested it on a 5 second music file. The initial ACX analysis is that the file is -0.09db peak so too high. The RMS level is -22.31 Pass Noise floor is -123.42 so too low. When I normalise the peak to -3 db it gets a pass but that also lowers the RMS down to 25.22 dB so that fails. The noise floor is now -120.34 db so still too low. How can I lower the peak without shunting the RMS low than the acceptable ACX range?

Well explained, concise, helpful🌟👏👍

Thank you

[@unrealrox]

Thank you for your explanation!. Please make a video regarding multiple music tracks normalization. I got music from different sources and I am a home user, I just need to hear them at the same volume. Greetings from Argentina.

[@NourAllam]

Great! How can I add "ACX Check" to Analyze menu?

[@KatieARowland]

that's a separate plugin, do a search for it and install it :)

[@LearnAudacity]

You can get it here: plugins.audacityteam.org/analyzers/analysis-plugins#acx-check

Thanks!

Hello Mike, I remember you from Udemy. How do I get ACX Check macro on Audacity?

[@LearnAudacity]

Hey Linda, you can log in to the Udemy course and grab it there still.

[@lindashaw1576]

@@LearnAudacity Thanks, I'll do that!

[@ExposedByJools]

I don't understand how you pass with a noise floor of 85.17?

[@LearnAudacity]

It has to be less than -60 but not silent.

[@ExposedByJools]

@@LearnAudacity ACX wouldn’t pass me at 65
