Exporting Sprectral data consistently

[Gale_Andrews]

I am attempting to compare a single wave form to determine if our audio system is operating consistently or if renegade changes are being made. To test my theory, I have a recorded waveform that I am using as a threshold. I import my threshold waveform and export its spectral data. Then without any changes I reopen the same threshold waveform and export the spectral data again. I expected that these two exports would be identical, but I am finding that the are not.

However, if I create a chirp sound and export it, then create a second chirp sound and export it as well, those to export files match identically.

How can audaity give me different spectral export data for the exact same file / settings?

Please provide the information requested in the pink panel at the top of the page.

You appear to have read Spectrum Comparisons Did you modify the waveform in any way after importing it a second time?

Is it a WAV file or a lossy format? You could attach or provide a link to your threshold waveform. See How to post an audio sample.
