Hello everyone, I have a question.
I did some acoustic measures for college work, and I want to use audacity to see the spectrum of these measures,
- Open audacity
- I have Imported to measurements made.
- I selected a piece of the action.
- I went to analyze → analyze spectrum.
- I obtained a graph.

NOTE: The piece I selected, was the calibration tone (94 dB SPL at 1kHz).
So, my question is on the graph:
In the graph img on the left side, I get negative values, I want to know which are referenced (by Audacity) these values (eg referenced to 1 volt, millivolt, etc.).
I think this refenciado to 1V / Pa
Thank you .
