![]() And that leads to the small, hard-to-hear waveform in the Audacity track.Īnd BTW, this is NOT just an Audacity thing. But either way, the result is a much-reduced level. ![]() But since my result was a one-third reduction (-30 dB vs -20 dB), I’m not sure that is correct. I’ve read that it’s trying to cut it in half. And it thinks it needs to reduce the input level… by a LOT. But since it is getting a stereo signal from the Scarlett interface, it sees a discrepancy. Since you have chosen “1 (Mono)” in the Audacity toolbar, it thinks you are recording a mono signal. That is the first issue.īut then Audacity does something odd. That means Audacity sees a stereo signal, even when you THINK you’re sending it a mono signal. It turns out that most 2-input interface units send all audio to the computer as stereo signals by default – regardless of how many mics you have plugged in. First of all, this isn’t ALL Audacity’s fault. If you thought that – like I did – you’d be wrong. It makes total sense that if you are recording a single voice into a single microphone plugged into a single microphone input on a recording interface, you’d choose “Mono.” Because, well, you’re recording a mono thing! There is a dropdown in Audacity’s toolbar where you choose between “1 (Mono) Recording Channel,” and “2 (Stereo) Recording Channels. Audacity has a weird conversion thing it does when it sees a stereo signal coming in, AND you choose the option (in Audacity) to record in mono. So Why Is This Happening?Īfter many days of searching for causes, I found the cause. The solutions and workarounds in this post work for both programs (and, I’m sure, any other program with this issue). [UPDATE: A very similar problem has been happening in Camtasia software for years and I only now realized it as the same basic cause. I’ve heard similar stories from others who are using interfaces with 2 mic inputs. This was a mystery to me, and only started happening when I updated Audacity to version 3.1. So this is a 10 dB difference! That means Audacity is lowering the level of the incoming signal by 10 dB. ![]() and the closer to zero you get, the louder it is. Remember in digital audio, things are measured in negative numbers. The Adobe Audition version’s average level was -20.47 LUFS. If you want the stats to compare, the Audacity version had an average level of -30.33 LUFS ( Loudness Unit Full Scale).
