Noise reduction and layering

Definitely the Zoom H1 is not the best gear for field recording, but for quick takes and because of its easiness of use (you can take it with you anywhere whenever you want) it’s quite a great tool. I decided to take three recordings from our long walk (read the previous post!) and I tried to isolate some interesting birds and insect sounds (remember: the H1 is a noisy one and doesn’t have the best mics available).

First of all, I removed all frequencies below 1200 Hz (insects and birds usually go over these frequencies) and, after filtering, I’ve used two different de-noising plugins: Brusfri, by Klevgr (that I didn’t used before, because I knew about it only a few weeks ago!), and the spectral denoise plugin from iZotope RX.

They use quite different approaches to reduce noise in a recording: Brusfri uses noise gating, iZotope uses phase cancellation, and both of them are superb doing what they do. But depending on the recording and the results we are looking for, you’ll probably use one or the other.

I’ve upload both results here, so you can use them in your own projects (commercial or not).  You will be able to perceive the gating effect when the Brusfri plugin is used, but certainly the noise floor is quite lower too. For demonstration purposes, I’ve created a video showing the differences between Brusfri and RX Spectral Denoise in each track. As you can see, I’ve been using the default settings in both plugins, just because I didn’t want to lose too much time tinkering with them. At the end, I was pretty satisfied with the results, considering the limitations and the overall quality of the original tracks!

After all the editing, I decided to design a complex ambience with the edited recordings, and layering them with a previous recording I did some weeks ago. The result is quite beautiful, and it will be sounding as a morning ambience loop in the game Travellers Rest by Loquo.
