Waveforms limited between -0.5 and 0.5


I am using a Focusrite Scarlett Solo connected with a USB to my PC with Windows 10, and a Supreme CU-1 mic to record vocals with Audacity. However, using the 32-bit float and a Mono track, there is a “cap” at -0.5 and 0.5 for the waveforms (and this is not caused by to low volume on the mic).

Using Stereo, this issue disapears, but I don’t have two recording sources, so I don’t want to do that. Any hints for how I could solve this issue?


Scarlett Solo has driver software available. That may help. Audacity gets its sound from Windows, not the device, so that’s a good place to address it.

We know what’s happening. When you tell the system to record in mono, it reduces the channel volume by half to “make room” in case both of the sound sources are the same and add. 0.5 or 50% is 6dB.

Some devices don’t do that shift between stereo and mono.

Post back if that helped. It’s a common problem.

If all else fails, use 50% as your new normal. Audacity doesn’t apply filters, effects or corrections on recording.


Here’s one.


He doesn’t address the half-volume thing, but I’m not on Windows, so I can’t tell.

Let us know if this works—or helps.


Thx! The youtube video solved for it :slight_smile:
