How to Fix Low Noise Floor for ACX in Audacity

Someone recently commented on one of my previous videos asking how to fix low noise floor in a project for ACX audiobooks. While the noise floor needs to be less than -60dB to meet ACX requirements, there cannot be silence in your recording. In this video I show you one way to raise your noise floor if it’s too low to meet ACX standards using Audacity.

Non-Destructive Editing Demo Using Audacity

In this short video I show how to edit your audio in Audacity non-destructively. Non-destructive editing was introduced into Audacity several versions ago and it’s a powerful tool to use because it enables you to go back to your original project file and make changes to your edits even after you’ve saved and closed the project. As Audacity progresses deeper into this mode of editing and realtime effects, it’s just going to get better and better. Links in this episode:

How to Apply Noise Reduction in Audacity

Reducing the amount of noise in a track is important for clean audio. Now that we have the ability to do it via realtime effects, it can be done non-destructively. But not everyone is on board with using realtime effects yet so I want to take a few minutes to show you how to apply the Noise Reduction effect that comes packaged with Audacity.

Destructive Editing vs Non-Destructive Editing Using Audacity 3.2.0

In this video I demonstrate the difference between non-destructive effects vs destructive effects in Audacity 3.2.0. Prior to Audacity 3.2.0 any effects added to a track were destructive, meaning each effect I added was embedded in the waveform itself, changing the waveform. As soon as I saved my project and closed the program, I could never undo what I had done. This is destructive editing. But starting with Audacity 3.2.0, that’s changed. We now have the option to use non-destructive editing where the effects I add don’t touch the waveform but remain external to it. This is non-destructive editing.
