Balance audio levels from different recordings

I am recording an audio book. After editing, I found some sentences that needed to be rerecorded. When I went back to the same studio and rerecorded everything, I found that they must have EQd their mics differently as the raw files sound very different than the original recordings. Even if I run them through the same filters as the original files and paste them in, there is a very distinct difference in sound.

How can I change the retakes raw file to have a similar sound/EQ to the original recordings so they match when I paste them in?

Thanks for your help. I’ve been beating my head against a wall trying to figure this out and couldn’t find the answer anywhere.

There are automatic EQ-matching plugin$ … https://youtu.be/GNqfyAa1jxk?&t=366

or In Audacity you can do frequency plots and compare them, then correct with an equaliser.

What did your studio say when you told them about the problem?

It is a church that uses it for their podcast, so I haven’t brought it up. It isn’t being run by an audio engineer. I’m not sure they would even remember the old settings. I am hoping an EQ fix this way would be easier than them guessing what the old settings were and then rerecording everything again.

The plot on the left is the original recording and the one one the right is the rerecording. I’m going to look into the EQ matching plugin because that sounds like exactly what I need. If not I’ll try to try your second option. Thank you so much!

I did ask the church today. They said they haven’t changed anything.

If you want the re-recording to sound more like the original, boost everything above 1000Hz by 6dB.

Is there a fast way to do that, or do I have to manually adjust everything in the filter curve EQ? This is my first time working with Audacity, so everything I do has a learning curve.

If you only have Audacity native tools, then there is no one-step fast way of matching the EQ.

Several cycles of trial and error : adjusting the EQ, then comparing the spectrums, wash rinse repeat.
