One of my lovely clients wrote me the other day in a panic:
“Hey, all of a sudden, something weird is happening when I record in Audacity.
I’ve always had my input level set at .6 or so, and have never touched it. But now, AS I’M RECORDING, the level is changing on me. I see it moving on the level slider!!! WHAT??”
I wrote her back and said that she shouldn’t worry, it’s nothing she’s done to Audacity, and that we can easily fix it.
Usually, you can “set and forget” the input level in Audacity, usually between .4 and .7 when you’re using our recommended AT2020-USB Plus mic, so that you get a robust waveform when you’re recording.
But sometimes, other pieces of software can start to modify that setting, in an attempt to keep you audible when you use that other software.
Skype is the most often cited, as is Zoom – they both have options that allow you to set automatic levelling of your microphone, so if you talk softer, the level goes up, and if you talk louder, the level goes down.
(We used to call that “riding gain” in radio.)
The dirty little secret is that if you have that option selected in any piece of software, all software that uses your microphone (including Audacity) are also affected.
(For my VOHeroes Pros only, I’ve recorded a video for the private Labs area that shows you exactly how to do this visually. Here’s the link to it: VO2GoGo Labs: How To Keep Audacity From Auto-Adjusting Input Levels)
And when that is the case, you can actually see the input level in Audacity (not Skype or Zoom or whatever) moving as you are speaking.
Let’s take Skype as an example. In its audio preferences, there is an option to have Skype “ride gain” on your mike volume.
Make sure you don’t use that option – ever.
Instead, make sure Skype is set like this, with the “Automatically adjust microphone settings” box unchecked in Preferences >> Audio/Video under the Microphone level meter:
Note that that check box is NOT checked, and that’s what you want.
Zoom, which we use for our live online monthly workout sessions and ProConnect Live accountability sessions, also can cause this. To prevent Zoom from taking over your computer’s audio leveling, go to Settings and choose Audio, then make sure Zoom’s similar option is NOT selected:
There may be other pieces of software, like other audio recorder/editors that might try these shenanigans. Treat them the same, and your Audacity levels will remain rock-steady.
Hope this helps.
