Frequency average of a sound track

[Aaran124]

Hello,
I’m using audacity for research on breathing soundtracks (from electronic auscultation).
For this research I need to get the average frequency of the entire soundtrack.

What I’ve already looked at :

• if i use the spectrogram view and select a box, i need to selsect from top to bottom, and the spectral selection toolbar doesn’t giv data when all is selected
• if I select a box an do analyse > plot spectrum, i can’t find the average frequency value.

Could someone help with this?

Thanks

Inès

You will need to decide how you want to calculate the “average” from the frequency data.

The raw frequency data can be exported from Plot Spectrum by clicking the “Export” button.

Hello Steve,

It would need to be a linear average.

Is there a simpler way to get it than exporting the data? As I will have to take aroung 500 averages (one per track).

Thanks a lot,

Inès

Calculating an “average frequency” is a very uncommon task in audio editing, so it is unsurprising that Audacity does not have a built-in feature to do that. I would suggest that you could either use Excel, or write a Python script to process the data exported from Plot Spectrum.
