We compared the signing certificate of this build with the certificate recorded the first time org.woheller69.audio_analyzer_for_android entered the site, and published both the file's SHA-256 and the certificate's fingerprint above so you can check the download yourself. That comparison says the file was not repackaged by someone else; it is not a review of what the app does.
The manifest declares 5 permissions, including access to the microphone. Android asks you to approve those the first time the app needs them.
