A collection of stuff so I can find it later.
Room Tone file and Noise Reduction
- Room tone is solely the sound of your environment once you’ve cleared all the elements you can control (like buzzing lights, fans, vents, etc.).
- Make all the recording adjustments (recording level, gain, etc.) you plan to use for your recording.
- Make a 35-second recording.
- Trim beginning and end so you don’t include the clicks and movements associated with starting/stopping the recording.
- Final recording should be somewhere between 10 and 30 seconds.
- Re-record whenever you enter a new recording environment, or if you move your mic.
Noise is anything beyond what you’re trying to capture — like the sound of a laptop while trying to record your voice. Make sure the room tone file is free of bumps, stomach gurgles, and any other evidence of your presence. Using this “blank” file, you’ll be able to create a noise profile you can use for cleaning up the sound in later recordings.
Caveat: I’m not sure if a long average (30 seconds of room noise) is more or less reliable for noise reduction than 5 seconds before and after the recording done that day. For example, there’s ambient birdsong in April that wouldn’t add to the noise profile for a December recording. This will be an ongoing experiment.
