How To Fix Loud Noise Floor, RMS, and Peak Values in Audacity to Meet ACX Standards
Вставка

- There's no substitute for a high-quality initial recording. Taking necessary steps to get the best recording possible saves time and a lot of headaches in post-production cleanup. There's no substitute for a pristine recording. But sometimes that just doesn't happen for any number of reasons. In this video I show you one way to clean up the noise floor in our ACX recordings using the Noise Reduction effect in Audacity as well as setting the RMS and peak values.

Thank you so much! You're the first person to explain this in a way that made sense, and now I am having SO MUCH less frustration in post-recording editing. I appreciate you immensely.
Oh my goodness, I have been searching and searching for this fix. You have just made my year. Thank you.
This is by FAR the best video I have seen on using audacity to meet Acx standards. Thank you!
Thank you!
Thank you! The noise floor issue about had me on the floor trying to fix it. This made it easy.
thank GOD for you i was almost in tears trying to figure this out!
You’re welcome. Glad I could help.
This video was HUGE for me. I saw the use of ACX check and set out to get the same ability. Make my project do-able. Thank you so much!
Thank you so much!! I passed all 3 and don’t have to redo the audio 👏🏽👏🏽👏🏽😭
Thanks for an excellent, no rambling, tutorial.

thank you thank you thaaaaank you!!!
Great video! Thank you! I have the problem that the noisefloor is too low is there a fix for that as well? Thanks again
LOL, I wondered if I had to keep wasting mouse clicks on that noise reduction for ACX levels! I've typically gotten the annoying "your noise level is too quiet. Dead silence is unnatural'
You're SUCH a time saver ♥🐾🐾✨✨
Thank you. Always glad to help!
I laughed at the "Click It" joke :) excellent video!
Hi Mike, I just purchased and learned from your fabulous class on "ACX Audiobook Production using Audacity." Awesome! It was exactly what I needed! The only thing missing in the class was in THIS video. If I needed to adjust noise floor levels like this, would I do it after applying the macros and during the final editing stage while dealing with any breath sounds, or would it become part of the macro chain itself? Thanks for all the help you're sending out to us newbies! Loved the class!
Thank you. I'll include it when I update the class content later this summer. I would be hesitant to put it in a macro, but that's just me.
Really useful, thank you. Do you know how difficult it is to track this stuff down? The Noise Floor is a real pain to lower. I'm trying both Dynamic Mic and Condenser mics. I'm on a M2 Mac Mini and I mostly use a condenser mic. It's pretty good quality - but perhaps not the best. So thank you for this great tutorial, I've learnt a LOT.
Excellent and clear explanation, thank you. Your help fixed my peak noise. However, my noise floor is too low. What can I do about this?
Thank you. One way to correct low noise floor is to add a second track to your project of just room tone and then include both tracks in your export. I have a 30-minute file of room tone I can make available to you if that would help. If you like, email me at audacitybootcamp@gmail.com and I can get it to you. I think a video on this would be good too. Thanks for the idea. :)
Thank you for this video! It helped me relax, and got all parts of my audio accompany to pass ACX check and the ACXlab. My audio accompany is only 10 minutes if read straight through. Would it be better to record the whole thing, get it passed then break it up? I'm only asking for the next project.
Apologies for the slow response. I like to record all at once as it makes it more uniform. If you record in pieces, make sure your recording environment is consistent and your mic technique is always the same.
can you repeat the process if it still has too high a noise floor?
Please tell me how I can fix the noise floor too low warning from ACX check (it says "Unnatural")
I took your udemy course and went on to narrate (voice over) a book I wrote and it has been for sale on Audible (ACX) ... everything worked as you taught. My question is will the macro's from that udemy course still work correctly with the upgrade to Audacity 3.2.5 ? Or am I missing updated information for that udemy course ? The de-clicker portion seems to run a really long time in the new Audacity, I don't remember that from before. I am more of a typical author, who can not afford voice over talent (maybe A.I. will fix that soon) and only does a book about once a year, so I tend to forget all of this audio+ACX+Audacity stuff. But having access to your UA-cam videos is a good refresher, but some other non-free tools (like iZotope) is way outside my means, but thanks again for your videos!
Thanks for taking my course! Yes, the macros will still work in the new versions of Audacity. That de-clicker takes a long time for me too. It's a resource-hungry plugin for sure. But it works great! Happy narrating!
Question on the noisefloor. If your not killing your noise floor how do u make sure your floor is low enough that it’s not bringing in mic noise, especially in gaps where your not speaking? When ever I record my mic is constantly bouncing at just below 54 even when I’m silent, which I guess is not too bad but obviously there’s noise there. Granted my rooms untreated, which brings me to my next question. If I’m going to treat my room to get rid of ambience which could potentially stop my mic bouncing when I’m not speaking, how do you treat the ambience in a way your not killing your noise floor? Coz surely it’s the room ambience that’s preventing your floor from not being dead even if ur in a naturally echoey room no? Coz obviously if the noisefloor is too low it says “sounds unnatural”
could I do that on multiple tracks at the same time? it will work?
I can't find where to download ACX check. I couldn't find it in the Plug-ins. Can anyone tell me where to find it?
Thank you. Question: I don’t see the Limiter in the Effects column or anywhere on the interface.
Glad you found it.
I followed all the steps and still do not meet the requirements and have no idea what I am doing wrong but I will look into your Using Audacity class. Thank you.
Question….please help me understand why all of my levels pass before exporting but when I import again or export, my peak levels are at or around 2.8ish…why and thank you!!
I just started recording my first Audio Book with ACX.I'm using version 3.4.2- My original recording is with a RodeCaster 2, then edit the audio in Logic ProX, and I was able to export and all my numbers pass ACX Audio test with one fail- RMS is -23.7. I'm having issues, but I will try your method. (Can you do this with my version 3.4.2 so I can understand better how to fix this?)
Hi Mike! M new here. Trying to record audiobooks and learn audacity. I don't see the option ACX check. Please tell me what do i need to do. Thank you
You’ll find it under the Analyze drop-down menu. You might be interested in my course since you’re new to audiobooks and Audacity. Check it out. www.audacitybootcamp.com/p/acx-audiobook-production-using-audacity
Yes fixed but so annoyed with this. Because the peaks go too high and it's like a seesaw. Noise floor too high peaks pass. Peaks pass noise floor too high ☹️
How did you get an acx check option via analyze option?
Try here. plugins.audacityteam.org/analyzers/analysis-plugins
Hi there I am 58 and have fibrofog so need an idiots guide to this. I did 3 books for ACX that were fine now I am back audacity has changed and it says I pass at 65.0 but ACX want me under 60.0 and I can't fathom what to do. The minus thing messes with my head and I can't make it all make sense. Any help would be great thanks. :0)
It seems so much louder than expected. Is this a normal production that will be different on Audible?
As long as your peak and RMS levels are within specs, you should be good to go. If you over-compress it can make it sound a little too loud as compressing can raise the quieter parts. Keep compression to a minimum.
When I edit this noise reduction it ruins the peak and rms levels when I follow this method. I don't know how to fix it without effecting the other items.
Try doing it first, before setting peak and RMS.
@@LearnAudacity That helped thanks. Wish it wouldn't distort my voice so much.
I found the Limiter.
Yay!!
YOU ONLY NEED NOISE REDUCTION, AND CLEAN ALL BACKGROUND NOISE
I don’t know why I’ve been thinking that acx didn’t want any unnatural means of lowering the noise floor. Ok, so I don’t need that 700 dollar booth then!
After a number of hours, lower one, the other one goes up. Lower it, the other one goes up. This is like herding cats...
I'm glad you didn't hit it,
