We’ve got a thread for mixing and mastering already, but I’m currently working on a long piece of field recording and that I took while I only had my zoom H1 and had to gain it all the way up . Now I’m in the position of working on reducing noise, cleaning up the recording, removing pops and noise, and getting gain corrected. I’ve never needed or wanted to ‘fix’ something in quite this state and I’ve got some questions!
I thought it might be nice to have a place to discuss the specific practice of doing restoration and repair work. (mods, feel free to merge this into something else if it seems appropriate )
There of course so many great plugins and systems to work with these days, especially the izotope stuff.
I’ll kick this off with my current situation. I was recording singing ice up near Ely, MN. This is when cracks in the ice as it forming cause incredible reverberant sounds to echo across the lake. On large lakes it can be quite loud and sustained. In the Boundary Waters (one of the quietest places in the USA) it’s really amazing.
So, I made a long recording, but I only had my old Zoom H1 at hand during the trip. I’m now battling to get the audio into a usable cleaned up state. I’ve got access to the Elements version of the Izotope plugins. RX Adaptive noise removal is great and doubling it up has been even better.
I’ve found that there is a sort of oscillation in the track that I don’t even know where to being to address, somewhere around 40hz.
(you can x out of the dropbox dialog box and listen/download)
Here’s an excerpt of the track with the oscillations:
and an excerpt of the singing ice for those interested:
I would be very grateful to hear any thoughts or ideas about cleaning up that thumping and any strategies you might have used to get noise like this under control beyond tossing some RX plugins over top!
