I think sox is what you want

I went ahead and asked a free AI how to use sox and played audio to trigger a script. Probably won’t be 100% accurate but maybe send you down the right path. Good luck.

1. Install ‘sox’ if you haven’t already. You can use the package manager of your Linux distribution to install it.

2. Open a terminal and use the ‘rec’ command from ‘sox’ to continuously listen to the audio input:

   sox -d -t .wav - silence 1 0.1 3% 1 1.0 3%
   

   This command will listen for audio and create a .wav file when it detects sound.

3. Write a script that will be triggered when a sound is detected. For example, you can create a script called “myscript.sh” with the following content:

   #!/bin/bash
   echo "Sound detected! Running my script."
   # Add your desired actions here
   

4. Make the script executable by running the following command in the terminal:

   chmod +x myscript.sh
   

5. Use the ‘rec’ command along with the ‘play’ command from ‘sox’ to continuously listen for sound and execute your script when sound is detected:

   sox -d -t .wav - silence 1 0.1 3% 1 1.0 3% | while read -r; do ./myscript.sh; done
   

   This command will continuously listen for sound and execute your script each time sound is detected.

Remember to customize the script “myscript.sh” with your desired actions.

Any of these

Install BiglyBT from fdroid. That is a torrent downloader for android. It has a search function to find torrents. Or you can search torrents using any number of websites.

As for quality and size… At this point in your journey you’ll have to sort and filter manually for those.

Also, you won’t find many guides for android and everything does lean heavy on PC. So if you can afford it eventually get yourself a cheap laptop, it’ll make things much easier for you.

I dunno if that’s actually an Alan Parsons quote but up vote for any mention of his name. Does sound like something he’d say.

Hopefully you have better luck with the batteries than I did
