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,
1) Open audacity
2) I have Imported to measurements made.
3) I selected a piece of the action.
4) I went to analyze -> analyze spectrum.
5) I obtained a graph.https://www.dropbox.com/s/2hfws7g7dfwqb ... 1.JPG?dl=0
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](Figure%201[/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 .
