Does Edge Impulse Scale Data once uploaded?

Question/Issue: Audio is being scaled during upload.
Project ID: 1052597
Steps Taken:

  1. I uploaded a wav file as recorded from a 24 bit mic sampling at 48000 Hz

  2. After I upload the data, Edge Impluse outputs this result:

  3. For clarity I also downloaded the same file from EI and plotted it

Expected Outcome:
Raw data shouldn’t change

Actual Outcome:
Based on plots it’s clear the data is being scaled once uploaded; but it’s not clear, why and by how much. Based on the wav header of the file after downloading from EI, each sample is now 2 bytes; but the file is somewhat corrupted because it’s also missing some bytes. So, maybe the wav header is also modified in a way that leaves data missing.

Reproducibility:

[x] Always
[ ] Sometimes
[ ] Rarely

Thanks!
