How To Fix Loud Noise Floor in Audacity to Meet ACX Standards

/ Mike Adams / Leave a comment

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.

Rode NT1 Mic Kit Unbox and Demo

/ Mike Adams / Leave a comment

I took the plunge and bought a Rode NT1 condenser mic. I’ve had my eye on this for quite some time and I’ve been comparing the specs of both the NT1 and the NT1-A. I decided on the NT1 because of its flatter frequency response, which I’ve discovered over the years compliments my voice better. I’m also warming up to the idea of starting into audiobook narration via ACX, so I needed a good quality condenser mic. And I found it in the Rode NT1. The kit includes not only the mic but a shock mount that holds both the mic and the included pop filter.
