Audio Manipulation Detection

Hi everyone!

I am looking for a software, platform, or automated solution to analyze a large batch of exported WhatsApp voice messages (.opus files) to determine how they were recorded.

Specifically, I want to categorize them into three types:

  • Natural: Recorded in one continuous go.
  • Studio-quality: Professionally produced/edited.
  • Highly edited: The user frequently used the WhatsApp pause/break button to piece the message together perfectly.

The Challenge: I ran some files through basic AI tools like Cleanvoice, but they often misinterpret the edits as normal breathing or simple pauses. However, when I look at the Audacity Spectrogram, I can clearly see hard cuts, phase shifts, and abrupt changes in the room tone (noise floor) right where the pause button was pressed.

Since I have hundreds of files, checking the spectrogram manually for each one is not feasible.

Is there any audio-forensics tool, python library (like librosa), or platform that can batch-analyze noise floor continuity or phase breaks to automatically flag these cuts?

Thanks in advance!
